Official BME690 Digital Sensor Nano Breakout 2.54mm – Temperature, Humidity, Pressure, Gas | I2C

The 7Semi BME690 Sensor Nano Breakout brings Bosch Sensortec’s next-generation environmental sensing technology into a compact, developer-friendly module designed for modern embedded applications. Built around the advanced Bosch BME690 sensor, this breakout board accurately measures temperature, relative humidity, barometric pressure, and gas parameters, including VOC and VSC detection, all from a single low-power device.

Engineered with 7Semi’s rugged nano breakout design, the BME690 module features a standard 2.54 mm pin pitch, making it fully breadboard-friendly and easy to integrate into prototypes, production designs, and educational projects. Operating at 3.3 V, it supports I²C communication, ensuring seamless compatibility with popular microcontrollers such as Arduino, ESP32, Raspberry Pi, STM32, and RP2040.

One of the key advantages of the 7Semi BME690 breakout is its support for Bosch’s BSEC (Bosch Software Environmental Cluster) library. This powerful software enables advanced signal processing and sensor fusion, allowing developers to extract meaningful air-quality data, including indoor air quality trends and gas index values, without complex calibration routines.

Designed for low-power operation, the BME690 is ideal for battery-powered IoT devices, smart home systems, wearable electronics, and environmental monitoring stations. Its compact size and high accuracy make it suitable for applications such as air-quality monitoring, HVAC systems, weather stations, industrial automation, and smart agriculture.

Whether you are building a prototype or deploying a scalable solution, the 7Semi BME690 Sensor Nano Breakout delivers professional-grade performance, reliability, and ease of use in a compact form factor.
