This week's EYE ON NPI smells so sweet, it's the BME688 digital nose gas sensor from Bosch! (https://www.digikey.com/en/product-highlight/b/bosch-sensortec/bme688-4-in-1-environmental-sensing) The BME680 is a very nice gas sensor released a few years ago, and remains the only temperature-humidity-pressure-gas sensors that we've ever seen. Small and easy to use, at Adafruit we've sold tens of thousands of BME680 sensors on breakout boards so we're very excited to see the next-generation of BME68x chips arriving and in stock at Digi-Key.

The BME688 is completely back compatible to the BME680, in fact over the weekend we added support to the latest Bosch C API (https://github.com/adafruit/Adafruit_BME680) So, like the BME680 you get a high-grade temperature, humidity and pressure sensor that can measure humidity with ±3% accuracy, barometric pressure with ±1 hPa absolute accuracy, and temperature with ±1.0°C accuracy. Because pressure changes with altitude, and the pressure measurements are so good, you can also use it as an altimeter with  ±1 meter or better accuracy!

I'm going to order some ASAP to turn into a breakout board, it looks like this chip is fully pin-compatible with the BME680 so if you need an example circuit that we know works, check out our open source BME680 design. (https://github.com/adafruit/Adafruit-BME680-PCB)  If you're looking for a great all-in-one sensor, and particularly if you've been using the BME680 and want to upgrade, there's thousands of BME688 stock at Digi-Key right now at a great price!
