Micro:bit Wireless Fine Dust Sensor

The fine dust sensor uses SHARP’s GP2Y1014AU0F. You can use anything compatible.
Micro:bit only works with v2.00 or later products.
Please use the Chrome browser if possible. It may not work in the in-app browser of social media (e.g. Facebook).
It works on a PC or Android device that supports Bluetooth. Operation on Apple devices is not guaranteed.
This app consumes a lot of CPU resources. Make sure your smart device’s CPU performance is good enough.
Firmware installation is required on the micro:bit for first use. Click the ‘Firmware Download’ link to install it on your micro:bit. You don’t need to access ‘makecode.microbit.org’ since you just need to save the file to the microbit folder.
A check mark(√) appears on the micro:bit’s LED when connected to the micro: bit.
If the connection doesn’t work, turn the micro:bit completely off and back on, or click the reset button on the back.
