Snow/Raindrops Detection Sensor Module โมดูลเซนเซอร์ตรวจจับความชื้นสำหรับ Arduino 1 ชุด / ล็อต

1set/lot Snow/Raindrops Detection Sensor Module Rain Weather Module Humidity For Arduino Product Summary: Robot kits , rain , rain sensor , can be used to monitor a variety of weather conditions , and turned into several fixed output signal and AO . 1, the sensor uses a high -quality double-sided FR-04 materials , the large area of 5.0\'\' 4.0CM, and nickel -plated surface , effective against oxidation, conductivity, superior performance and lifetime areas ; 2 , the comparator output signal clean waveform is good , driving ability, than 15mA; 3 , power bits adjust the sensitivity ; 4, Working voltage 3.3V-5V 5, the output format : Digital switching output ( 0 and 1 ) and analog voltage output AO ; 6, with bolt holes for easy installation 7 , a small board PCB size : 3.2cm x 1.4cm 8 , using a wide voltage LM393 comparator Connect the 5V power supply , power indicator light , sensor board does not drop when , DO output is high , the switch lights off , dripping a drop of water , DO output is low , the switch indicator light, Brush above water droplets, has returned to the output high state. . . . AO analog output can be connected to the microcontroller detects AD mouth drops of rain in the above size. DO TTL digital outputs can also be connected to the microcontroller detects whether there is rain . 1×RainDrop Module With Cable #Raindrops #Detection #Sensor Module #Rain Weather #Module #Humidity #Arduino Before purchase: 1.All the goods are ready stock, we will arrange the shipment at once if we receive the order. 2.Please read the item description, if you have any question, do not hesitate to contact us. 3.No warranty,if you receive a defect item,please contact us at once with item picture. 4.Use the vouchers for more saving.
