8 SPST-NO Rpi IoT Power Relay Module for Raspberry Pi A+ 3A+ B+ 2B 3B 3B+ 4b

This is a simple and practical water sensor relay module, relay output switch SPDT (Single Pole Double Throw). If the 2 sensor wires P1 and P2 of the module come into contact with water, the built-in relay switch action, C to NO connected and C to NC disconnect, otherwise the relay switch will release, C to NO disconnect and C to NC connected. The module must a power supply DC 10 ~ 15V to V+ / GND. Operating current 50mA.
