Raindrops Detection Sensor Module – Weather Sensor for Arduino

The Raindrops Detection Sensor Module is a smart solution for detecting rainfall and monitoring weather conditions in electronics, Arduino, and automation projects.

🔹 Rain Detection Functionality:

• Detects the presence of raindrops and measures rainfall intensity

• Converts water presence into both digital and analog output signals

🔹 Working Principle:

• Uses a rain board to collect raindrops

• As water collects, resistance drops, changing the analog voltage output

• Dry board = High voltage (up to 5V)

• Wet board = Lower voltage

🔹 Based on LM393 Comparator:

• Ensures accurate signal comparison

• Outputs clean digital signals (0 or 1) and analog AO voltages

🔹 Microcontroller Compatibility:

• Works with Arduino, Raspberry Pi, ESP8266, and other TTL-compatible boards

🔹 Operating Voltage:

• Runs on 5V DC, standard for most development boards

🔹 Adjustable Sensitivity:

• Built-in potentiometer for fine-tuning detection threshold

🔹 Durable & High-Quality Build:

• Uses FR-04 double-layer PCB material

• Nickel-plated surface for anti-oxidation and longer life

• Large detection area: 5.5 x 4.0 cm

🔹 Easy to Mount:

• Includes bolt holes for secure installation

✅ Applications:

• Rain-sensing smart systems

• Weather stations and monitoring setups

• Automatic wiper activation in robotics

• IoT-based environmental monitoring

• Agricultural automation and smart irrigation systems

• Smart home window closure systems

✅ Features Summary:

• LM393 comparator-based design

• TTL and analog signal outputs

• Output indicator LED

• Adjustable sensitivity

• Stable signal with strong drive capacity

• Durable and corrosion-resistant surface

• Suitable for all weather detection projects

✅ Package Includes:

• 1 x Rain Water Collection Board (sensor plate)
