Product description: Temperature, humidity, pressure and gas sensor - BME688 - SPI / I2C - STEMMA QT / Qwiic - Adafruit 5046
Multifunctional sensorcombining sensors fortemperature,humidity, pressure and VOC gas measurement. It has an integratedBME688chip from Bosch. Manufactured by Adafruit, it uses SPI and I2C buses to communicate with the main module. It works with controllers such as Arduino and Raspberry Pi.
TheBME688sensor has a smallMOXsensor built in. The heated metal oxide changes resistance based on volatile organic compounds (VOCs) that are in the air, so it can detect gases and alcohols such as ethanol, alcohol, and carbon monoxide. It can also be used to perform air purity measurements.
Contents of the kit
- Temperature, humidity, pressure and gas sensor - BME688
- Goldpin 1x8 strip - 2,54 mm pitch
Product is compatible with Arduino and Raspberry Pi!
A detaileduser guideis available on the manufacturer's website, which makes getting started with the sensor much easier. It includes description of leads, connection diagrams, libraries for particular programming environments and sample program codes.
Connection diagram of sensor with Metro board - equivalent of Arduino. Metro board is not a part of kit, you can buy it separately in our shop.
Sensor pinout description from Adafruit
Multifunction sensor module has solderingfields, to which you should solder includedgoldpinstrip (pinout is 2,54 mm). On the board there are alsoSTEMMA QT / Qwiicconnectors which are more convenient alternative to connect the sensor with the controller. You should connect the leads according to the relation below:
- VIN - power supply pin from 3V to 5.5V
- 3Vo - power supply pin 3.3 V
- GND - system ground
- SCK / SDO / SDI - logic pins of SPI / I2C communication interface
- SCK - communication interface clock line
- SDI - communication interface data line
- CS - Chip Select pin
