I have started today with a N-240 Pengcheng kit with an Arduino UNO. There is no description of the sensors but with the inscriptions I've identified all sensors but one. It is a black long dome shaped sensor. Does anyone have an idea what this sensor does? (see photo)
But that is only the storage box, with nothing inside ... ?
I think you have to use it without an english description. There is almost no information about it.
If you want a cheap sensor, you can find it on Ebay.
