Adafruit BME680 - Temperature, Humidity, Pressure and Gas Sensor
12 units available with a short lead time.
The BME680 from Bosch delivers comprehensive environmental sensing in a single compact package. This precision sensor measures temperature, humidity, barometric pressure, and VOC gas levels, all accessible over I2C or SPI.
In addition to standard environmental readings, the BME680 includes a small MOX (metal oxide) sensor that changes resistance based on volatile organic compounds in the air. This enables detection of gases and alcohols such as ethanol and carbon monoxide, making it suitable for air quality monitoring. Note that it provides a single overall VOC resistance value and cannot differentiate between individual gases.
