3-Pack Rain Detection Sensor Module for Weather & Humidity Monitoring

Description:

Experience seamless weather monitoring with our comprehensive Robot Kit Rain Sensor. Perfect for diverse weather conditions, this sensor efficiently converts weather data into a reference signal and AO output.

• Built with high-quality FR-04 double-sided materials, the sensor measures 5.0cm x 4.0cm and features a nickel plating treatment to resist oxidation, ensuring superior conductivity and longevity.
• Outputs include digital switching (0 and 1) and analog AO voltage output, providing versatile data handling.
• The TTL-level output is low when valid, boasting a driving capability of 100MA, making it ideal to directly power relays, buzzers, small fans, and more.
• Adjust the sensitivity easily via the potentiometer.
• The LED indicator provides clear visual feedback: it lights up when there is no rain, and as raindrops increase, the output level changes accordingly.

Specification:

• Small board PCB size: 3.2cm x 1.4cm
• Operating voltage: 3.3V-5V

Features:

• Adjustable sensitivity distribution bit
• Fixed bolt hole for easy installation
• Power indicator and output signal LED indicator
• Comparator output provides a clean signal waveform, with a driving capability of over 15mA
• Wide voltage LM393 comparator
• Large rain detection area for improved accuracy
• Separate raindrop and control panels for simplified wiring

How to Use:

1. Connect to a 5V power supply. When the sensor board is dry, the DO output is high, and the indicator is off. When a drop of water is detected, DO output turns low, triggering the indicator light. Once the water is removed, DO output returns high.
2. The AO analog output can be interfaced with a microcontroller AD port to measure rainfall intensity.
3. The DO TTL digital output can be connected to a microcontroller to detect the presence of rain.

Connection Mode:

• VCC: Positive power supply (3-5V)
• GND: Ground
• DO: TTL switching signal output
• AO: Analog signal output

Package Includes:

• 3x Rain sensing boards
• 3x Control boards
• 3x 20cm Dupont Line sets
