The MonkMakes Plant Monitor is a capacitive moisture meter that also measures temperature and relative humidity. Because it’s a capacitive moisture sensor, there is no electrical contact with the soil, so the probe doesn’t corrode in the way that resistive sensors do.
In this guide, you will learn how to use the Plant Monitor’s serial (UART) interface with CircuitPython. As an example, you’ll use the ten Neopixel LEDs on a Circuit Playground Express to indicate the moisture level.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
