Product description: Air Quality Control - shield for Raspberry Pi - Kitronik 5038
Air Quality Control is another extension from Kitronik , which allows you to expand the Raspberry Pi board and equips it with additional functionalities. The shield has pins for connecting a wide range of sensors, it also offers the ability to effectively record, store and display data using the Pi file system and OLED display . It has been equipped with the popular BME688 system, which allows you to measure temperature, pressure, humidity , air quality and eCO2. The module is compatible with all Raspberry Pi versions equipped with a 40-pin GPIO connector.
Air Quality Control - extension for Raspberry Pi - Kitronik 5038.
Raspberry Pi must be purchased separately.
Special features of the plate
- Enables monitoring and logging of data that can be displayed on an OLED screen with a resolution of 128 x 64 px
