BME680 measures pressure, humidity, temperature and indoor air quality

The BME680 measures pressure, humidity, temperature and indoor air quality. by Bosch Sensortec:

BME680 is an integrated environmental sensor developed specifically for mobile applications and wearables where size and low power consumption are key requirements. Expanding Bosch Sensortec’s existing family of environmental sensors, the BME680 integrates for the first time individual high linearity and high accuracy sensors for gas, pressure, humidity and temperature. It consists of an 8-pin metal-lid 3.0 x 3.0 x 0.95 mm³ LGA package which is designed for optimized consumption depending on the specific operating mode, long term stability and high EMC robustness.

Air quality sensor detects microscopic pollutants

Mitsubishi Electric announced that it has developed a small, high-precision air-quality sensor, the world first to detect all fine particles measuring no more than 2.5 micrometers in diameter, called PM2.5, as well as pollen and dust. It also senses the density of particles precisely.

Scattered light from PM2.5 particles is measured with Mitsubishi Electric’s unique double-sided mirror design, which collects about 1.8 times more scattered light than conventional single-sided designs. An air flow controller provides stable airflow. Components were optimally designed to achieve a small form factor and were carefully aligned to avoid obstructing the airflow and laser beams. Mitsubishi Electric’s original shape-discrimination algorithm distinguishes between pollen and dust based on the respective differences in the optical characteristics of their scattered light, resulting in the world’s first sensor capable of detecting all PM2.5, pollen and dust particles.
