BME690 Environmental Sensor Breakout Board

Featuring one of the most advanced sensors in Bosch's lineup, the BME690 Breakout Board adds air quality measurement on top of environmental (temperature, humidity, and pressure) sensing. With features such as Volatile Organic Compounds (VOCs), Volatile Sulfur Compounds (VSCs), and other gases, the BME690 provides an excellent upgrade to the BME688, especially for high condensation environments. Accuracy and applications can be further fine-tuned using Bosch's BME AI-Studio to tune the BME690.
