10pcs Snow Raindrops Humidity Rain Weather Detect Sensor Module Geekcreit for Arduino - products that work with official

Description The item is forrobot 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 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 output in the form digital switching outputs 0 and 1 and analog AO voltage output 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 potentiometerLED lights up when there is no rain output is high raindrop up the output ground level LED light Feature Distribution bit to adjust sensitivityA fixed bolt hole for easy installationPower indicator the output signal LED indicatorThe comparator output the signal is clean waveform driving ability over 15mAWide voltage LM393 comparatorA large area of rain board more conducive to detect rainBoard with positioning holes to facilitate installationRaindrops and control panels are separate easy to wire leadsSpecification Small board PCB size 3 2cm x 1 4cmOperating voltage 3 3V 5VVoltage 5VHow to use Connected to 5V power supply the power indicator light sensor board is not water droplets DO output is high the switch lights off dropping on a drop of water DO output is low the indicator light switch Brush
