`b-parasite <https://github.com/rbaron/b-parasite>`__ is an open source soil moisture and ambient temperature/humidity sensor.

The ``b_parasite`` sensor platform tracks b-parasite's Bluetooth Low Energy (BLE) advertisement packets. These packets contains soil moisture, air temperature/humidity and battery voltage data.
