Product Description

This product is retired and we won’t sell it anymore. This page is for reference only.


The AQ:bit is an addon for the popular micro:bit. The AQ stands for atmospheric quality meaning that the AQ:bit can be used to measure weather and atmospheric conditions, such as current temperature, pressure, humidity, and particle count when connected to a micro:bit.

The AQ:bit allows the micro:bit to send atmospheric data over the Internet. The AQ:bit becomes operational once the micro:bit slides into the appropriate header located on the top section of the board. When the micro:bit is required elsewhere, the AQ:bit can be detached from the micro:bit.
Temperature measurement is done with the TMP236A2DCKR and BME280 sensors, while the latter can also collect data on humidity and pressure. The PMS7003 particulate matter sensor connects via the 10-pin female header on the bottom of the board and provides information on the air quality using PM2.5 and PM10 readings.

The AQ:bit is equipped with an easyC connector that enables it to be connected with other boards. Additionally, the AQ:bit has an USB-C connector for charging and features the powerful ESP8266MOD that grants access to WiFi networks.
