An open source DIY soil moisture sensor with ambient temperature, humidity, and light sensing, built on nRF52840/nRF52833 hardware and powered by a CR2032 coin cell. The repository hosts open hardware designs plus firmware samples that broadcast sensor readings over BLE (Home Assistant/BTHome compatible) or Zigbee.
Use cases
- monitor houseplant soil moisture wirelessly
- build a DIY BLE soil moisture sensor
- integrate plant sensors with Home Assistant
- measure ambient temperature and humidity with a coin cell sensor
- calibrate a capacitive soil moisture sensor
- experiment with Zigbee on nRF52
When to choose
- you want an open source, open hardware plant monitoring sensor
- you need multi-year battery life from a coin cell
- you use Home Assistant with BLE or Zigbee integrations
- you want to learn nRF52 embedded development
When to avoid
- you need a ready-made commercial product rather than a DIY PCB you assemble and flash
- you need Wi-Fi or cloud connectivity instead of BLE/Zigbee
- you require a formal software license for the code
