🌱💧 A Bluetooth Low Energy (BLE) soil moisture sensor.
b-parasite is an open source soil moisture and ambient temperature/humidity/light sensor.
This repository also hosts a few different firmware samples for b-parasite.
| Sample | Description | Extra Documentation |
|---|---|---|
| samples/ble | This is the most battle-tested and useful firmware. It periodically reads all sensors and broadcast them via Bluetooth Low Energy (BLE). It works with Home Assistant + BTHome out of the box. | Docs |
| samples/zigbee | An experimental/educational/exploratory basic Zigbee sample built on nRF Connect + ZBOSS. It integrates with Home Assistant via ZHA or Zigbee2MQTT. | Docs |
| samples/blinky | The classic “Hello, world” | - |
| samples/soil_read_loop | Reads the soil moisture sensor on a loop. Useful for experimenting and calibrating the sensor. | - |
| samples/input | Handles button presses. Useful for power profiling GPIO interrupts and testing debouncing for push switches on boards that have them. | - |
Information about how to order, assemble, build the samples, protect the sensor and flash the firmware is on the Wiki.
