Air Quality and Environmental is an extension board for the micro:bit. It gives you the ability to monitor the air quality and environment in a given environment. The data is displayed directly on the OLED display, which is located in the middle of the board. The board includes an integrated connector for the BBC micro:bit. Built-in sensors allow you to read temperature, pressure, humidity, air quality index and eCO2. The product can be powered by AA batteries or via the microUSB port. It is also possible to charge it with solar cell, remember to put NiMh batteries in the basket then. It is suitable for various projects at home or at school.
BBC micro:bit board not included, can be purchased separately.
