2 Introduction

The BME680 environmental sensor board is a compact board that provides all environmental sensing. It

provides temperature, humidity, pressure, and VOC gas. The board is based on BME680 environmental

sensor module. BME680 is a sensor that integrates high-linearity and high-accuracy gas, pressure,

humidity, and temperature sensors with low power consumption. The BME680 has optimized

consumption, long-term stability, and high EMC robustness. To measure air quality for personal wellbeing

the gas sensor within the BME680 can detect a broad range of gases such as volatile organic compounds

(VOC).

3 Feature Highlights

• Environmental sensing for temperature, humidity, pressure, gas in a single module
