(+1Month Warranty) Water Raindrops Weather Rain Sensor Module - Analog & Digital for Arduino [ElectricA]

Product Description:
- Rain Sensor Module is used to measure or detect the rainfall. 
- Can be used in various weather conditions
- It comes with 2 output pins which are digital and analog. 
- User can choose to use the digital or analog output. 
- Rain Sensor detects the rainfall by using 2 tracks on the PCB board. 
- When the water or rain drops to the surface of the plate, the resistance between the tracks will change as the water making tracks conduct each other.  
- More water or rain touches the plate, resistance become lower.  

Specification:
- Sensor using high quality material on both sides, oversized 5.0*4.0CM, with nickel plated surface against oxidation, electrical conductivity, and life more superior performance;
- Comparator output signal clean wave good driving ability, than 15mA;
- Power adjust sensitivity;
- Rated voltage and 3.3V-5V
- Output: digital switching output (0 and 1) and AO analog voltage output;
- With fixing bolt holes for easy installation
- Small Board PCB dimensions: 3.2cm x 1.4cm
- Using wide LM393 voltage comparator

Package Included:
- 1 x Smart Home Weather Monitoring Rain Sensor Module 
- 1 x Jumper Cables
- 1 x LM393 Signal Conditioning Module
