Basic two-piece water sensor which measures the soil moisture. The sensor connects to the sensor module which manages the digital and analog output.

It operates on 3.3V - 5V and has a digital output as well as an analog output

For the digital output, the potentiometer can be used to trigger the change between HIGH and LOW.

Features:

  • Sensor and module separate
  • LM393 comparator
  • Dual output (Digital or analogue)
  • Power indicator
  • Digital mode indicator
  • Variable voltage between 3.3V and 5V
  • Module connector spacing to suit breadboard
  • VCC can be powered from digital out - to switch sensor on and off through code
