Wireless Water Level Sensor is a device used to sense the level of liquid within a tank.
The sensor may actuate a pump, an indicator, an alarm, or other device. This is a brand new mini liquid float switch without mercury. It could be used in most liquid environments.
Mainly used for wireless home and business alarm system. Use them with pumps, ponds, basement, boats, automobiles, or whatever your project may be.

LED Indication of alarm and low battery
Built-in Battery: 23A-12V battery (included, useful life time 6-12 months)
Size: 70mm x 40mm x 15mm (antenna not included)
Emission Frequency: We can offer 315 MHz or 433 MHz, you can choose one.
Oscillation resistor / Timing resistor: We can offer 1.2M, 1.5M, 1.8M, 2.2M, 3.3M or 4.7M, you can choose one.
Install the float switch to the position in a tank you want to detect. When the water reach the position, the float switch will be triggered, LED 1 on transmitter will turn on red light for 5 seconds and the transmitter will send out alarming signal.
Indication of low battery: When the voltage of battery is less than 7.5V, LED 2 will straightly turn on red light. At this time, you must immediately change the battery.
