The Monk Makes Plant Monitor is a capacitive soil moisture sensor combined with temperature and relative humidity measurement! This sensor uses a capacitive sensor which resists corrosion much better than traditional soil moisture sensors.
Thanks to the capacitive prongs and onboard AHT10 temperature and humidity sensor, you can keep an eye on your plant's soil moisture levels whilst also monitoring its local conditions, feeding data to your favourite microcontroller via serial for your project to use!
Once powered up, the plant monitor will immediately start displaying the level of wetness using the builtin LED. Red means dry, green means wet. Before you put the Plant Monitor in the pot, try gripping the prong in your hand and the moisture of your body should be enough to alter the LED's colour.
