Reference
This article provides a comprehensive guide on using a humidity sensor with Arduino or micro:bit for rain monitoring, explaining the fundamental principle of output signal variation with changes in humidity levels.
Usage Description
The sensor can sense the humidity in environment. Using with Arduino or micro:bit to make rain monitoring device.
The more water on the detection area, the larger the output signal, and vice versa.
