A simple case for the capacitive soil moisture sensor from april brother.

The advantage of a capacitive soil sensor is, that you can leave it in the soil as the contacts do not corrode.

If printed in PETG this case can be used outside to measure the moisture for a long period of time. You can use the sensor readings for your home automation and connect your automatic watering system to it.

Check out my code for this sensor which publishes the readings over MQTT. You will find the Fusion360 sources there as well: https://github.com/MoJo2600/esp-soil-moisture-sensor
