Water Level / Rain Drop Sensor Module

Raindrop & Water Level Detection Sensor Module

This module consists of a double-sided nickel-plated sensor board that tracks water droplets through conductive bridging across parallel PCB tracks. Paired with an LM393 comparator module, it delivers real-time analog rainwater depth and a digital precipitation alarm.
