SKU: VE-073 Category: Sensors

The Raindrop Detection Sensor Module is an easy-to-use, dual-module weather monitoring peripheral designed to sense the presence and relative intensity of precipitation. It consists of a dedicated nickel-coated sensing pad connected to an electronic driver board utilizing an LM393 voltage comparator chip. Operating on a resistance-bridging principle, the module detects moisture whenever water droplets bridge the exposed conductive tracks, allowing developers to automate systems based on real-time rainfall data.

✨ Key Features

Dual Output Modes: Provides both a simple high/low digital switching signal and an informative analog voltage output for tracking rainfall severity.
Adjustable Threshold Sensitivity: Integrated onboard potentiometer allows precise fine-tuning of the rain detection trigger point.
Dual LED Indicators: Features independent onboard LEDs to provide visual feedback for system power and active digital output triggering.
Weather-Resistant Sensing Surface: The large tracking pad features a durable, anti-oxidation nickel coating to prevent premature corrosion over outdoor lifespans
