Hello everyone,

First of all, I would like to introduce you to our AirSENSE project Github. This is a research lab project aimed at developing devices to measure indoor and outdoor air quality, as well as circuits for air purifiers.

I noticed the 2024 Business Card Contest and thought I should do something. I want to share with everyone the handheld circuit device we have created: The circuit uses an ESP32, features real-time modules, an SD card slot, battery charging module, and can connect to the PMS7003 dust sensor and the BME280 temperature and humidity sensor.

I don't have much experience sharing projects like this, so if you have any questions or suggestions for improvement, please send them to me.
