3Pcs 3.3-5V High Sensitivity Water Sensor Module Kit for Monitoring Various Weather Conditions

Description Connect the 5V power supply the power indicator is on and when there is no water drop on the sensor board the DO output is high the switch indicator is off a drop of water is dropped the DO output is low and the switch indicator is on Brush off the water droplets on it and then 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 rain falling on it The DO TTL digital output can also be connected to the microcontroller to detect whether there is rain Features 1 The sensor adopts high quality FR 04 double sided material a large area of ​​5 0 4 0CM and the surface is treated with nickel plating which has superior performance in terms of oxidation resistance conductivity and life 2 Comparator output clean signal good waveform strong driving ability more than 15mA 3 Adjust sensitivity of power distribution positioner 4 Working voltage 3 3V 5V5 Output form digital switch output 0 and 1 and analog AO voltage output 6 With fixing bolt holes for easy installation7 Small board PCB size 3 2cm x 1 4cm8 Use wide voltage LM393 comparatorApplications The robot kit raindrops and rain sensors can be used to monitor various weather conditions and convert them into digital signals and AO outputs Wiring 1 VCC Connect the positive pole of the power supply 3 5V 2 GND connect to the negative pole of the power supply3 DO TTL switch signal output4 AO ana
