Pleas help me

Hello! I have a quick question and would really appreciate some help with a school project. I’m working with a dust sensor to measure air quality/dust percentage. I already have the code ready, but I’m not sure how to physically wire and connect the sensor. If anyone could guide me with the wiring, I’d be very grateful!😅

You need to provide a link to the sensor.

Also, your code. For example if in the code you said use I2C, then the connections would be different if you used SPI, and would be different if you used analog read.

Also it is a pretty bold statement that the "code is ready" but you didn't even wire the sensor up yet. Usually the code isn't ready until you have at least tried it with the final target environment.

Perhaps have a look at rule 2 which in part says you need to provide details such as your code and links to the stuff you are using.
