Adafruit Monk Makes Plant Monitor - Capacitive Moisture Meter

If you've ever struggled to maintain happy plants, the Plant Monitor from Ada-friend Monk Makes is an effortless solution to keep your greenery thriving. This garden-stake-shaped PCB offers precise capacitive soil moisture measurement with just one probe, ensuring no exposed metal and corrosion-free contacts, making it a lasting companion for plant care.

In addition to soil moisture, the device measures temperature and relative humidity, delivering comprehensive environmental insights for your plants. Compatible with BBC micro:bit, Raspberry Pi, Pico, Pico W, and most microcontroller boards, it connects easily with alligator clip pads.

Features include ready-soldered header pins and a simple UART serial interface, with an additional analog output for moisture measurement. A built-in RGB LED provides a visual indicator for real-time monitoring. Note that it requires hardware serial support for Arduino-IDE devices, as it doesn't work with SoftwareSerial, like the ESP8266.
