Small size, fast response. Gnd: power supply is negative 3. Vcc: positive power supply 3-5V 2. Sensor performance and features: -The sensor adopts high-quality FR-04 double-sided material, with a large area raindrop test of 5. 4*4. 0cm, more conducive to the detection of rain. And is treated with nickel-plated surface, the waveform is good, electrical conductivity and life - the comparator output, the signal is clean, which has superior performance against oxidation, the driving ability is strong, more than 15mA - Adjust sensitivity with potentiometer - Voltage: 5V -Output form: digital switch output 0 and 1 and analog AO voltage output; -with fixed bolt holes for easy installation -PCB size: 5.
XLX 5 Sets Rain Drops Sensor Module Weather Detection Monitor Large Area Raindrop Module Highly Sensitive Humidity High Efficient 3.3~5V for Arduino Weather #ad - 5cm x 4cm -function: use wide voltage lm393 comparator function introduction: connect 5v power supply, power indicator light is on, DO output is high level, brush the water drop above, there is no water drop on sensor board, DO output is low level The switch indicator light is on, switch indicator is off, drop a drop of water, and return to the output high level state.
Ao analog output, can be connected to the AD port of the single-chip microcomputer to detect the amount of rainfall dripping on it. With fixing screw hole, strong vibration resistance, convenient for install and fixed. High reliability, low power consumption, good electromechanical performance, long signal transmission distance.
