Overview

This module can be used for weather status, raindrop sensing, and for monitoring variety of environment conditions.

The DO TTL pins are digital outputs and they can be connected to the microcontroller for detect the raindrop.

The AO analog output can be connected to the microcontroller AD port to detect  the size or the amount of the drops from the rainfall.
