Tired of wilted plants? Automate your troubles away with this soil moisture sensor!
This sensor reduces corrosion by sensing water capacitively instead of resistively, so water never comes into direct contact with the metal portion of the sensor.
You'll need an analog-to-digital converter to get this sensor working with a Raspberry Pi.
To calibrate the sensor, record the reading when completely dry, and immerse the sensor in water, recording the result (making sure not to get the capacitors and resistors wet).
Map between the two values and experiment with thresholds for each plant!
