moisture sensor image

Requirements

  • PWM pin on at least 1 MHz microcontroller
  • ADC input pin to read sensor value

Code

  • The code was written for an Atmega 328p based Arduino Nano but should work for any microcontroller with identical registers
  • PWM duty cycle depends on microcontroller voltage. Try what results in the greatest range of voltage for your project
