SW02 - VOC and Weather Sensor (BME680)

Overview

This xCHIP is a digital 4-in-1 sensor with gas, humidity, pressure and temperature measurement.

Product Highlights

• I2C digital interface up to 3.4 MHz

Applications

• Indoor air quality
• Home automation
• Internet of things
• Weather forecast
• GPS enhancement (e.g. time-to-first-fix improvement, dead reckoning, slope detection)
• Indoor navigation (change of floor detection, elevator detection)
• Outdoor navigation, leisure and sports applications
• Vertical velocity indication (rise/sink speed)
