7Semi BME690 IAQ Air Quality Sensor Nano Breakout 1.27mm Pitch Header

7Semi BME690 IAQ Air Quality Sensor Nano Breakout 1.27mm Pitch Header: High-Accuracy Environmental Sensing for Embedded Applications
The 7Semi BME690 IAQ Sensor Nano Breakout integrates Bosch Sensortecs latest 4-in-1 air quality sensing technology in a compact, reliable form factor. Designed for smart devices and IoT applications, it combines measurement of temperature, humidity, barometric pressure, and gas (VOC/VSC detection) with ultra-low power operation.
Engineered for robustness and power efficiency, the BME690 is optimised for long-term stability even in high-condensation environments. Its compatibility with I2C (up to 3.4 MHz), 3.3 V supply, and Bosch BSEC software ensures seamless integration for developers working on air quality monitoring, wearable devices, smart homes, and industrial IoT systems.
