Using this PM2.5 air quality sensor and breadboard adapter kit is a breeze. First, connect the sensor to a microcontroller with UART input. If you want, you can also use a USB - Serial converter and parse the data on your computer. We've provided code for Arduino and CircuitPython to make it easier for you. Once it's connected and powered up with 5V (the logic level is 3.3V), you'll start getting data every second. Just one data pin for UART TX is needed. When handling the kit, be careful not to damage the sensor or the cable. Keep it in a dry place to avoid any moisture - related issues. As for maintenance, there's not much you need to do. Just make sure the connections are secure. If you have any trouble, refer to our guide for wiring diagrams and code.
