Grove – Temperature, Humidity, Pressure and Gas Sensor

This standalone environmental sensor BME688 is a high-performance 4-in-1 gas sensor with Artificial Intelligence (AI), integrated high-linearity and high-accuracy pressure, humidity and temperature sensors. It can measure humidity with ±3% accuracy, barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy just like its predecessor BME280 & BMP280. Because pressure changes with altitude and the pressure measurements are so good, you can also use it as an altimeter with ±1 meter or better accuracy.

The new BME 688 sensor it’s backward compatible with BME680. Compared to BME680, it carries an extra gas scanning function with low power consumption (3.9 mA in standard gas scan mode). It can detect a wide variety of volatile organic compounds (VOCs), volatile sulfur compounds (VSCs), and other gases such as carbon monoxide and hydrogen in the part per billion (ppb) range. In standard configuration, the presence of VSCs is detected as an indicator for e.g. bacteria growth. The gas scanner can be customized with respect to sensitivity, selectivity, data rate and power consumption as well. Moreover, it is trainable to detect different gas mixtures and their presence (e.g. coffee) with Bosch’s AI Studio like in home appliances, IoT products or Smart homes.

This new BME688 is ideal for innovative custom applications such as detecting food spoilage or timely detection of wildfires by measuring current gases and tracking changes in temperature and humidity. The artificial intelligence capabilities of the sensors and Bosch Sensortec’s new BME AI-Studio software tool allow customers to quickly develop custom solutions directly for their specific use cases.
