ITEM NAME:Humidity Detection Sensor Module Rain Detection for Description: robot kits, rain, rain sensor, can be used for all kinds of weather monitoring, and translated into output signals and AO. Use the high quality FR - 04 double material, large area of 5.0 * 4.0 CM, treatment of nickel plating and surface, have fight oxidation, electrical conductivity, and life has more superior performance; Comparator output, signal clean, good waveform, strong driving ability which is more than 15 ma Adjustment sensitivity with potentiometer Working voltage of 3.3 V to 5 V Output format: digital switch output (0 and 1) and analog AO voltage output; Fxed bolt hole, convenient installation Small board PCB size: 3.2 cm x 1.4 cm Use wide voltage comparator LM393 Specification: Connected to 5 v power supply, power indicator, no water droplets on induction plate, the DO output high level, switch indicator light out, drop a drop of water on, the DO output for the low level, the switch light is lit,Brush away the water droplets, again to return to, the output high level... AO analog output, which can be connected to the microcontroller AD mouth detection drops of rainfall in the above size. DO TTL digital output also can connect to the single chip microcomputer detect whether there is rain. Connection mode: 1. VCC: positive (3-5 v) 2. GND: connect power anode 3. DO: TTL switch signal output 4. AO: analog signal output Package Includes: 1x Rain module 1x Chip 1x Wire.Robot kits, rain, rain sensor, can be used for all kinds of weather monitoring, and translated into output signals and AO. 1x Rain module. DO TTL digital output also can connect to the single chip microcomputer detect whether there is rain.
