Rain High Sensitive Module

High-Sensitivity Conductive Grid: Features a nickel-plated, anti-oxidation rain board matrix designed to detect individual water droplets and micro-precipitation instantly.

LM393 Voltage Comparator Circuitry: Onboard LM393 differential comparator delivers clean, noise-free digital switching signals to microcontrollers.

Dual Output Mode Options: Provides a continuous Analog Output (AO) for quantitative droplet/moisture depth monitoring and a Digital Output (DO) for direct logic threshold switching.

Onboard Sensitivity Trimmer: Includes an adjustable potentiometer to let you set precise moisture triggers for automated relays and alarm systems.

Visual LED Telemetry Indicators: Outfitted with a power indicator LED and a digital switching output status LED for quick visual status checks.

Board Material: Heavy-duty FR-4 glass-epoxy sensing plate with nickel-plated tracks for long-term oxidation resistance; FR-4 breakout control module board.

Technical Specifications:

Sensor Type: High-Sensitivity Raindrop / Precipitation Sensor Kit.

Operating Supply Voltage: 3.3V – 5.0V DC.

Signal Outputs: Dual Analog (AO) + Digital Switching (DO).

Comparator IC: LM393 Differential Comparator.

Board Color: Black PCB with Silver Sensing Grid Lines.

Usage Advice: Mount the rain sensing board at an angle to allow water to run off naturally; connect VCC, GND, and use AO for analog depth logging or DO for direct digital threshold switching.

Maintenance: Gently wipe away mineral scale, dust, or grease from the nickel grid surface with isopropyl alcohol to maintain peak sensitivity over time.

Essential All-Weather Automation Component: Position as an indispensable precipitation sensor for automated window closers, smart laundry shade retractors, greenhouse ventilation systems, and DIY weather stations.

Highlight Dual-Board Modular Construction: Emphasize how separating the exposed outdoor rain collector plate from the control module protects sensitive electronic ICs from weathering and physical damage.
