Bosch BME680 is a 4-in-1 air quality sensor measuring relative humidity, barometric pressure, ambient temperature, and gas (VOC) levels. It’s found in boards such as STM32 based Metriful Sense or Nordic Thingy:91, and Bosch Sensortec published an Arduino library based on “Bosch Sensortec Environmental Cluster (BSEC) Software” to provide precise calculations temperature, humidity, pressure, and indoor air quality (IAQ). BSEC proprietary algorithms can provide indoor air quality data as good as more expensive CO2 sensors according to a recent presentation by the company. Max Prokhorov, lead ESPurna maintainer, and Rui Marinho noticed none of the popular open-source ESP8266 automation firmware including ESPurna, Tasmota, and Esphome supported BME680 sensor just yet. So they decided to work together to add BME680 sensor support via BSEC library to ESPurna firmware, and now it’s very easy to use as you just need to define BME680_SUPPORT=1 before compiling the firmware. You’ll find the now-merged pull request here. The feature was previously discussed in Tasmota, but […]
