This is a PM sensor + Qwiic adaptor board product, you will get the PM sensor and an easy to use adaptor board.
The PM sensor is a compact (compare to the other PM sensors) and accurate sensor. It can directly output the PM 1.0, 2.5, 10.0 rate of the air in unit of the µg/m3 (PM standard unit), just like the weather report.
This is an I2C version of the sensor, which also has UART interface version. The adaptor board can be directly attached to the sensor with the female header, and we offer you two ways to setup the connection, the easiest way is to use Qwiic cable to connect to Qwiic connector, with no soldering; another way is soldering the breakout pins.
The adaptor board can be fixed very well by the 2.0 mm screws with the two 2.0 mm holes on the board. And there are two 3 mm mounting holes for you to fix this module to any other place you want.
Note 1: the fan on the sensor needs 5v to drive it. We have added a voltage step-up circuit to convert the I2C 3.3V (Qwiic connector) to 5V for the fan. So please be sure to use 5V power when you are using these breakout pins.
Note 2: The sensor needs to take around 30s to warm up to get the accurate data.
