BME688 Details
The BME688 is a highly compact 4-in-1 environmental sensor capable of measuring gas, temperature, humidity, and barometric pressure with high accuracy, all in a package as small as 3mm × 3mm × 0.93mm. It integrates advanced sensing technology, making it ideal for portable, wearable, and IoT applications. The sensor supports both I²C and SPI communication, as shown in the pinout diagram, allowing easy interfacing with microcontrollers. In the application circuit, the BME688 is connected with pull-up resistors and decoupling capacitors for stable operation. Its ability to simultaneously provide multiple environmental parameters makes it highly suitable for air quality monitoring, weather stations, smart home devices, and health-tracking systems
