Rain Water Level/height Sensor

Parallel Conductive Trace Matrix: Employs an array of exposed, parallel copper lines that measure changes in electrical resistance as water immersion level or raindrop contact increases.

Direct Microcontroller Compatibility: Outputs a continuous analog voltage signal directly readable by Analog-to-Digital Converter (ADC) pins on Arduino, ESP32, and Raspberry Pi boards.

Plug-and-Play 3-Pin Interface: Standard 3-pin layout (Signal, VCC, GND) enables simple hookup using standard female-to-female DuPont jumper cables.

Low Power Draw & Broad Rail Input: Operates efficiently on standard 3.3V - 5V DC logic power, making it ideal for battery-powered IoT telemetry nodes.

Compact Submersible Breakout Design: Slim, lightweight board profile fits easily into tight liquid reservoirs, sumps, and narrow drainage channels.

Board Material: High-grade FR-4 glass-epoxy PCB with tin-plated trace arrays and red solder mask.

Technical Specifications:

Sensor Type: Analog Water Level / Raindrop Sensor Breakout.

Operating Supply Voltage: 3.3V – 5.0V DC.

Signal Output: Analog Voltage Output.

Board Color: Red PCB with Silver Sensing Traces.

Usage Advice: Connect VCC (3.3V - 5V), GND, and Signal (S) pins to your microcontroller board; calibrate analog readings in your code to map voltage to specific depth levels.

Maintenance: Keep the top connector pin area dry; periodically wipe mineral deposits and dirt off the copper trace grid using isopropyl alcohol.

Essential Liquid Level & Moisture Sensor: Position as a low-cost, indispensable sensor for smart home leak detection, automated bilge pumps, plant watering stations, and rainwater harvesting tanks.

Highlight Linear Level Telemetry: Emphasize how the analog trace array provides proportional height data rather than just binary wet/dry detection.

Recommended Cross-Sell Add-ons: Pair with ACEBOTT Water Level Sensor Droplet Detection Module Easy-Plug Compatible with ESP32/Arduino, Rain/Water level sensor with JST interface, Rain High Sensitive Module, and ESD antistatic mat 50x40CM PCB Welding Mat.
