LoRa Wireless Flood Alarm Sensor AN-204E

AN-204E wireless flooding alarm is mainly used to detect flooding. The alarm uses a wire-type detection rope. The sensor detects whether water leakage occurs based on the principle of liquid conduction. When any part of the detection rope touches water, the two sensing lines will short-circuit. The alarm judges the water leakage according to the change in the resistance of the detection rope. And send out an alarm signal. The alarm has a built-in omnidirectional antenna, which is easy to install and can be widely used in communication base stations, precision computer rooms, libraries, exhibition halls, museums and other application scenarios that require waterproofing.
