Hi, @ahmadsuki!
Here it is a plain ambient air pollution module from Seed Studio. The module based on the MP503 gas sensor.
The data is read from the sensor via a single analog port, for example, A0. In total, the module uses 3 wires to connect V, G, A0.
Now there is no official XOD library for working with this sensor. But it doesn’t matter because the sensor is quite simple, and you can try to create nodes to work by yourself. This module is an excellent source to make the XOD library by wrapping a third-party Arduino library.
As an example, I quickly made the XOD library based on the library from the manufacturer, but I can’t check it because I don’t have this module.

In theory, it should work correctly. The sensor returns one of four values 0, 1, 2, 3. Each value corresponds to the pollution degree of the surrounding air.
Try it.
