Meet Teapotlabs Plantpal - Your pal in plant care! This adorable device uses capacitive sensing to measure soil moisture. Its low-power e-paper display keeps you updated without draining energy. Plus, with the BME688 sensor, it is able to monitor air quality and CO2 levels, ensuring your plants thrive in optimal conditions.

More details can be found in Plantpal Github.

Teapotlabs Plantpal is part of Teapotlabs open-hardware project.
