DESCRIPTION
The long-awaited BME688 from Bosch gives you all the environmental sensing you want in one small package. This little sensor contains temperature, humidity, barometric pressure, and VOC gas sensing capabilities. All over SPI or I2C at a great price!
The BME688 is a 'drop in' replacement for the BME680 - it adds a method of programming the gas-sensor heater for controlled odor-analysis but is otherwise the same hardware.
Like the BME280 & BMP280, this precision sensor from Bosch 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!
Please note this sensor, like all VOC/gas sensors, has variability, and to get precise measurements you will want to calibrate it against known sources!
For your convenience, we've pick-and-placed the sensor on a PCB with a 3.3V regulator and some level shifting, so it can be easily used with your favorite 3.3V or 5V microcontroller. All of the pins of the BME688 are available on standard 0.100”/ 2.54mm pitch headers for use with a breadboard. Should you wish to avoid soldering, we now also include our Stemma QT connectors (SparkFun Qwiic compatible). Using these handy connectors you can simply plug in the sensor, no soldering required!
