Air quality and environment module for micro:bit
-
Provides detailed air quality data (temperature, pressure, humidity, air quality index, and eCO2) from multiple on-board sensors
-
The collected data can be stored in the onboard EEPROM memory (1 Mbit) and displayed on the integrated 128x64 OLED screen or transferred to a computer for in-depth analysis.
-
A real-time clock (RTC) enables timestamped data recording
-
Compatible with BBC micro:bit board, with edge connector connection
