10pcs Snow Raindrops Humidity Rain Weather Detect Sensor Module For Arduino

Description: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.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 off the the above water droplets, has returned to output high state. . . .AO analog output can be connected to the microcontroller AD port to detect the size of the drops in the above rainfall.DO TTL digital outputs can also be connected to the microcontroller detects whether there is rain.Connection mode:1, VCC: positive power supply (3-5V)2, GND: negative one.3, DO: TTL switching signal output4, AO: Analog signal outputPackage included:10 x Rain sensing board10 x Control board50 x 20cm Dupont Line
