Raindrops Detection Sensor Module

The item is for Arduino robot kit, raindrops, rain sensor, monitoring can be used for a variety of weather conditions, and converted into the number of the reference signal and the AO output.

Specifications

• The sensor uses the FR-04 high-quality double-sided materials, King Size 5.0 * 4.0CM, and with the surface of the nickel plating treatment, against oxidative, conductivity, superior performance and longevity;
• The comparator output, the signal is clean, waveform, driving ability over 15mA;
• Distribution bit to adjust sensitivity;
• Operating voltage 3.3V-5V
• The output in the form: digital switching outputs (0 and 1) and analog AO voltage output;
• A fixed bolt hole for easy installation
• Voltage: 5V
• Power indicator, the output signal LED indicator.
• TTL-level output, TTL output valid signal is low. Driving capability 100MA so, can directly drive relays, buzzer, a small fan, and so on.
• Sensitivity can be adjusted via potentiometer
• LED lights up when there is no rain output is high, raindrop up, the output ground level, LED light. 
• Raindrops and control panels are separate, easy to wire leads.
• A large area of rain board, more conducive to detect rain. 
• Board with positioning holes to facilitate installation
• Small board PCB size: 3.2cm x 1.4cm
• Wide voltage LM393 comparator
