ACE 6769 Rain Detection Module Moisture Sensor for Arduino STM32

This rain sensor consists of two modules: a rain board that detects the rain and a control module which compares the analog value and converts it to a digital value.

Features:

• LED lamp indicator for output signal
• TTL level output
• Able to drive about 100 mA; can add relay, buzzer, small fan, etc.
• Sensitivity adjustment through the potentiometer
• When the LED is ON: output is HIGH, not rain. LED is OFF if output is lOW, raining
• Rain sensor board and control board are connected through wires
• Holes on Rain Sensor board to drain raindrops easily
• With bolt holes for easy installation
