1pcs/3pcs 3.3-5V mưa hạt mưa cảm biến thăm dò mưa mô-đun thời tiết Mô đun độ ẩm

Product use: Arduino ROBOT KIT, rain shower, rain sensor can be used to monitor a variety of weather conditions and convert it to digital signal and AO output Product Description: 1.The sensor uses high quality. FR-04 double-sided material, large area 5.0*4.0cm, and the surface is treated with nickel plating, which has better performance in terms of oxidation resistance, electrical conductivity and life2.3. Compare the signal clean, good waveform, strong driving ability, more than 15mA; Adjust the sensitivity of the position of the power distribution 4. Working voltage 3.3V-5V5 Output format: digital switch output (0 and 1) and analog voltage AO output; 6. By installing a bolt hole for installation7. Easy, small PCB board size: 3.2cm x 1.4cm8, use the comparison identification function. LM393 multi-voltage: 5V power supply is connected, the indicator is on, when there is no drip on the sensor board, the output is high, the switch indicator light is off, the submerged drop shape and low light level The switch indicator light is on, the droplets are rounded off and the output is high again. Analog AO output can be connected to the microcontroller ADS port to detect the amount of rain falling. TTL do digital output can also be connected to the microcontroller to determine whether there is rain or not. Wiring mode: 1. VCC: connected to the positive pole of the power supply (3-5V) 2. GND: connected to the negative pole of the power supply 3. DONE: TTL Switch output signal 4. AO: signal Analog signal output
