LoRa Wireless Flood Alarm Sensor AN-204B

AN-204B wireless flooding alarm is mainly used to detect flooding. Based on the principle of liquid conduction, when the probe is immersed in water, the electrode conducts and an alarm is triggered. Built-in omnidirectional antenna, easy to install, can be widely used in: communication base stations, precision machine rooms, libraries, exhibition halls, museums and other application scenarios that require waterproofing.
