The BME680 is a digital 4-in-1 sensor with gas, humidity, pressure, and temperature measurement based on proven sensing principles. The state-of-the-art BME680 breakout lets you measure temperature, pressure, humidity, and indoor air quality, and is Raspberry Pi and Arduino-compatible!

The sensor module is housed in an extremely compact metal-lid LGA package with a footprint of only 3.0 × 3.0 mm² with a maximum height of 1.00 mm (0.93 ± 0.07 mm). Its small dimensions and its low power consumption enable the integration in battery-powered or frequency-coupled devices, such as handsets or wearables.

Typical applications

You can use this breakout to monitor every aspect of your indoor environment. Its gas resistance readings will react to changes in volatile organic compounds and can be combined with humidity readings to give a measure of indoor air quality. Here are the list of typical applications:


 Indoor air quality
 Home automation and control
 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)

Features

  • Measuring temperature, pressure, humidity, air quality sensor
  • I2C interface, with address select via ADDR solder bridge (0x76 or 0x77)
  • 3.3V or 5V compatible
  • Reverse polarity protection
  • Raspberry Pi-compatible pinout (pins 1, 3, 5, 7, 9)
  • Compatible with all models of Raspberry Pi, and Arduino
  • Python library
  • Datasheet

Let us see how we can get started with BME680 on the NVIDIA Jetson Nano board:

Pre-requisite:

  • BME680 sensor
  • Jetson Nano

Installing software

  • Use i2cdetect command to detect the sensor
pico@pico1:~$ i2cdetect -r -y 1
