We have a client who has an airstrip with AC220V runway lighting on the runway and a DC12V solar windsock light. The runway lights are 1000 meters away from the customer’s building and the solar lights are 150 meters away from the runway lights. When the plane lands, he needs to turn on both the runway lights and the solar windsock light at the same time.

The runway light is turned on / off by a manual switch from the building, however, he needs to walk up to the solar windsock light at 1000 meters to turn on the solar windsock light. For ease of operation, the windsock light is set from dusk to dawn has been open. But one of his neighbors complained that the windsock light have been lit to disturb the lives of them. So he told us the details of the situation by mail description clearly and wanted a wireless control solution to solve this problem. He demanded that he didn’t want to connect a control line from the solar windsock light to the building because it was 1000M away, the wiring was too cumbersome and the cost was too high. He wanted to install a wireless control system between the runway lights and the solar windsock lights so that they could operate simultaneously. In other words, when the runway lights are turned on, the solar lights are automatically turned on at the same time. When the runway lights are turned off, the solar windsock lights are also automatically shut down at the same time.

We recommend to customers based on the actual situation and customer requirements, a wireless lamp remote control equipment. The device includes a receiver S1X-DC12-ANT3 (model 0020490) and a transmitter CB-2V-AC (model 0021048). This transmitter is an ac power trigger type remote control, and it has two input lines. When an ac voltage is input, the transmitter is triggered and a radio control signal “on” is transmitted. When AC voltage stops input, the transmitter is also triggered and a wireless control signal “OFF” is transmitted. The receiver is DC 12V input / output type, the maximum operating current is 10A, and it has a waterproof case and external telescopic antenna, so it can be installed outdoors. This wireless light remote control device in the open area can be achieved as far as 1000 meters working distance. The user first connects the runway light’s AC220V power supply to the transmitter’s two input lines, and then the windsock light to the receiver’s output terminals.

The wireless light remote control device example picture and the specific operation are as follows:

When the user opens the runway light from the building, the transmitter (CB-2V-AC) detects that its two input lines have AC voltage inputs, then it transmits an “ON” wireless signal to the receiver. When the receiver (S1X-DC12-ANT3) received this wireless signal, it outputs a 12V power to turn on the windsock light. When the user turns off the runway lights from the building, the transmitter (CB-2V-AC) detects that the AC voltage has ceased to be input, then it transmits another “OFF” wireless signal to the receiver. When the receiver (S1X-DC12-ANT3) received this wireless signal, it stops the output 12V power, windsock light is turned off.

This type of wireless remote control device can use one AC or DC device to wirelessly control another AC or DC device, and it can be used in many applications, such as lighting control of a port or a dock, remote control of industrial equipment, remote control offshore platform or onboard equipments.

Nowadays, the world is facing the problem of power shortage. Street lighting and guiding lights are indispensable facilities in daily life, and we put forward higher requirements on the energy saving of street lighting. Traditional street lamp control methods include manual control, automatic clock control, light induction control, SMS control, etc., but those ways can’t achieve the control requirements under special conditions. Like during construction, when a device is turned on, automatically turn on street lighting in order to effectively use lighting to avoid waste. Therefore, the radio frequency remote control system can be integrated with the management of street lighting, which is to achieve high-performance automated, intelligent lighting management, and reduce operational and maintenance costs.

The radio frequency wireless control system is composed of transmitter and receiver. There are two types of transmitters. 1. DC power (DC5V ~ 28V) trigger type, such as the transmitter CB-2V (model 0021044); 2. AC power (AC100 ~ 240V) trigger type, such as the transmitter CB-2V-AC (model 0021048). Both transmitters can work with different receivers. And there are three types of receivers. 1. DC power output type, such as the receivers S1X-DC (model 0020423) or S1PX-DC (0020436), they are usually used to control DC equipment; 2. AC power output type, such as the receivers S1X-AC (model 0020391) or S1PX-AC (model 0020440), they are usually used to control AC equipment; 3. The relay output type, such as the receivers S1L-DC (model 0020042), S1U-AC (model 0020330), S1PU-DC (model 0020046) or S1PU-AC (model 0020275). It is equivalent to a single-pole double-throw switch with a relay output, and the relay has three output terminals, normally closed, normally open and common terminal. These receivers are usually used to control various DC / AC equipments.

Users choose different transmitter and receiver for different combinations, and it can achieve different control methods. 1. Use one AC device to wirelessly control another AC device. 2. Use one DC device to wirelessly control another DC device. 3. Use one AC device to wirelessly control another DC device. 4. Use one DC device to wirelessly control another AC device, etc.

The working principle:

When the transmitter detects a DC or AC power trigger signal, it automatically emits an “ON” wireless signal, which is equivalent to the function of the button “ON” on the transmitter. When this power trigger signal is turned off or the power trigger signal is stopped, the transmitter automatically transmits another “OFF” wireless signal, which is equivalent to the function of the button “OFF” on the transmitter. When the receiver receives the “ON” or “OFF” wireless signal that will drive its relay to turn the connected device on or off.

Notice: The operating voltage of the transmitter is DC9V, and it can work for about 3 days with a model 6F22 9V battery. If the device has to work long term, we recommend using a DC9V power adapter.

How to wireless monitor the working status of AC Pump?

With the increasing progress of science and technology, people require the electronic appliance with more automation and intelligence. Now, intelligent control system is adopting wireless remote control technique instead of traditional wire control technique, which can avoid the problems caused by wiring and adding new devices. In order to make the function of the wireless remote control traditional device isn’t limited by distance and space. It’s a more convenient method to be compare with traditional wire control.

Wired control technology:

Wired control technology is a relatively primitive technology. It adopts the pattern of integrated wiring, used in household, agriculture, industry, equipment erection, such as security systems, lighting control, heating, air conditioning, water control, etc., This technology is connected directly to the device through wire connections to achieve a single control or integrated application control function.


  1. It is necessary to install a large number of wires, the installation method is complicated, and the wiring cost is too high.
  2. The control panel of operation is fixed, so it is not convenient to use and can’t be freely controlled in any space.

Wireless control technology:

Radio frequency wireless control technology is a novel technology. People first simply connect controlled devices to wireless receivers by a simple wired connection, then achieve the wireless control function of connected devices through the transmitters or remote control.


  1. Simple installation, no need to install a large number of wires, the cost is greatly reduced.
  2. Portable remote control can be carried out in any reliable range for wireless control and convenient operation.
  3. Wireless control technology can achieve wireless control at a considerable distance, such as 1000M or further.

The wireless control system consists of a transmitter or remote control and a receiver. The transmitter or the remote control is made up of the keys, the coding circuit, the modulation circuit, the signal amplifying circuit and the antenna. Working principle of the Transmitter: The transmitter generates a specific signal when the button is pressed. Then this signal is processed by the modulation circuit, coding circuit and high-frequency amplifier circuit. Eventually it generates a radio wave, and this radio wave is emitted by the antenna. The receiver is made up of receiving antennas, RF receiving modules, decoding circuits, driving circuits and relays, and driving circuits and relays must be connected to the controlled devices. Working principle of the receiver: When the transmitter sends a RF wireless signal, the receiver receives this RF wireless signal through the antenna of the RF module, and then the wireless signal is analyzed and determined by the decoding circuit. Finally, according to the specific information of this RF wireless signal, the connected devices can be operated accordingly by driving circuit and relays. For example, a variety of lighting on / off, the door open / closed, the pump on / off operation, the motor forward and reverse control, air conditioning heating or ventilation system control, linear actuators telescopic control, vehicle equipment Wireless control, automation control of agricultural greenhouses, or other industrial equipment movement control and so on.

As we know, Radio frequency signals are transmitted through the media, generally the media is air. There are mainly three factors affecting the working distance of an RF wireless system. One is the receiver’s sensitivity of receiving wireless signals, and the other is the transmitter’s transmit power. The last one is the obstacles between the transmitter and the receiver. Suppose there are some obstacles in the propagation path, such as walls, high buildings, trees, cars, etc. These obstacles will seriously reduce the wireless transmission distance of radio frequency signals. For this reason, we propose two options to solve the problem.

  1. Replace the high-power remote control, ex. the working distance of normal CWB type waterproof remote control is only 50 meters, but the CP type remote control can reach 500 meters, and CB type remote control can reach further 1000 meters.
  2. Replacing the receiver’s RF antenna, using an external antenna with higher receiving sensitivity, such as external telescopic antenna or external magnetic sucker antenna.

One of our customers purchased a wireless remote control device from Carymart online shop, and successfully erected an AC water pump wireless control system, with a control distance of 1000 meters. The wireless pump remote control system includes a receiver (model:S1PX- AC220-ANT3) and a transmitter (model CB-2). This receiver is the ac power output type, and the maximum working current is 30A, it has the waterproof shell and the external telescopic antenna, which can be installed in the outdoor use. However, in practical application, the client encountered another problem that he cannot confirm the working condition of the AC pump from such a long distance through visual and auditory sense. When he presses the button of the remote and opens the ac pump through the receiver, the pump is working, but he can’t confirm the state of the work. Because he couldn’t see the pump, he worried the wireless signal was disturbed by other factors, so that the water pump could not be opened properly. Based on this situation, we have developed a visual status solution. Install a current sensing switch (model 0025011) on the AC pump, then install an indicator light (model 0040026) at the height position. The customer can confirm the working status of the AC pump by observing this indicator light. Working principle of the Current sensing switch: When it detects the current of the wire passing through its inspection hole, it will close its internal contacts and turn on the status indicator.

Their connection diagram and installation diagram as shown below:


The specific operation of wireless water pump remote control equipment with status indicator are as follows:

When the customer is within reliable control, he first presses the button A on the remote control CB-2. If the receiver normally receives this wireless signal, it will turn on the water pump. At the same time, the status indicator light installed at the top will also be turned on. So the customer can see the status lights in the distance, and confirm the pump is working properly. When the customer presses the button B on the remote to turn off the pump if the receiver normally receives the wireless signal. At the same time, the state indicator light will be extinguished, and the customer can confirm that the pump is in a state of suspended operation.

Such a wireless remote control device can also be equally applied to agricultural long-distance irrigation, household water storage wireless control, garden watering remote control, long-distance control of industrial equipments, remote control offshore platform or onboard equipments.
