Capacitive Soil Moisture Control Board Detection Sensor Analog Output DIY Electronic for Arduino and Raspberry Pi

Work perfectly, I read the data line in an analog pin for an ATMega328P and was really easy to use. To anybody else who does this: when the sensor is fully submerged it should output 300, and fully dry should be around 600.I am going to have to buy some silicone sealer though, as the circuitry on this product doesn't appear to be waterproof, which isn't ideal for most of its applications.. (but who can complain at this price).

This product works but the bare edges of the probe need to be sealed to prevent eventual degradation. Also, the analog output needs to be linearlized since it is very non-linear.
