Whether deployed in their thousands in an industrial greenhouse or just one in your plant pot growing experiment, soil moisture sensors can increase the chance of your plants thriving.

  connects to a power supply and a GPIO pin to supply moisture data to a microcontroller. It’s aimed primarily for use with the Raspberry Pi and integrates well with the opensource automated irrigation and environmental control system.

With the supplied documentation and the neat example python script it should be relatively straightforward to use this sensor with numerous microcontroller platforms as part of your system. Supplied assembled, there are options for just the sensor or a “water repellent” version with a cable attached and some weatherproofing applied to the upper section of the sensor.
