Water / Rain / Liquid Sensor Module (Arduino compatible)

Water / Rain / Liquid Sensor Module (Arduino compatible)
  • Product Code: SE-ED01-09-0120
  • Availability: In Stock - Ships in 1 to 2 days



  • Voltage: 5V
  • Have power indicator, output signal LED indicator.
  • TTL-level output, TTL output valid signal is low, drive capacity at 100MA, can directly drive relays, buzzer, a small fan, and so on.
  • Sensitivity adjustable via potentiometer
  • Raindrops sensor and the control board are separate.
  • Board with positioning holes to facilitate installation
  • Control panel board size: 3 x 1.6 cm
  • The raindrop detection plate large area 5.4 x 4.0 cm


  • Connect to 5V power supply power lights. When the board has no water droplets, DO output is high and the switch indicator light is off. Dropping a drop of water on sensor board will make DO output as low, and switches the indicator lights on.
  • AO analog output can be connected to the MCU AD port to detect the drops of water.
  • DO TTL digital outputs can also be connected to the MCU detects whether there is rain.
