[CNX-Software] - b-parasite Bluetooth LE plant sensor gets Zigbee support

rbaron’s b-parasite is an open-source hardware Bluetooth LE plant watering sensor that can measure soil moisture and ambient temperature/humidity/light and works with ESPHome, Home Assistant, or any macOS or Linux platforms including the Raspberry Pi boards. It is based nRF52840 multi-protocol wireless microcontroller, so stanvn decided to add Zigbee support to the b-parasite through the “Zigbee Plant Sensor” firmware based on the Nordic Semi nRF5 SDK for nRF52 series of SoCs and working with Zigbee2MQTT. Let’s have a look at b-parasite hardware specifications first: Wireless MCU – Nordic Semi nRF52840 Arm Cortex-M4F multi-protocol wireless microcontroller with Bluetooth LE 5.0 and 802.15.4 (Zigbee/Thread) radios, 1024 KB flash, 256KB SRAM Sensors Capacitive soil moisture sensor Sensirion SHTC3 temperature and humidity sensor ALS-PT19 light sensor Power – ~200 mAh CR2032 coin-cell battery estimated to last for a couple of years with readings every 10 minutes The GitHub repository for the board contains the [...]
