Performance metrics for the BME680 indicate a 4-in-1 MEMS architecture capable of measuring temperature, humidity, barometric pressure, and volatile organic compounds (VOCs). Technical documentation identifies a pressure sensor precision of ±0.12 hPa. The gas sensor component functions by measuring resistance shifts in a metal oxide layer, requiring a 48-hour initial burn-in and a 30-minute warm-up cycle for stable baseline reporting.
The hardware utilizes the I2C and SPI communication protocols. To prevent thermal bias from self-heating, the sensor must be isolated from heat-generating components such as microcontrollers. The module includes a voltage regulator compatible with 3.3V to 5V power sources and integrated pull-up resistors on the breakout board.
The SHT45 Precision Temp & Humidity Sensor Module is a recommended alternative for environments where gas sensing is not required but extreme temperature accuracy is paramount.
This unit is categorized under multi-metric air quality monitors.
