The sensor array can measure different environmental factors like climate, noise, ambient light, and even different smells using AI on the edge. It can also control IR devices such as air-conditioners. This combination offers flexibility and cost-effectiveness for monitoring multiple environmental conditions in various applications, including intelligent buildings, agriculture, and industrial process control.
BME688 is an integrated environmental sensor that combines multiple measurements, including temperature, humidity, pressure, and volatile organic compounds (VOCs), in a single package. BME688 also has a gas scanner function, distinguishing pre-trained gasses with AI.
