3Pcs HC-SR04 Ultrasonic Ranging Sensor Ultrasonic

Online Shopping 3Pcs HC-SR04 Ultrasonic Ranging Sensor Ultrasonic Module For ArduinoDescription:Working Voltage : 5V(DC)Static Current: Less than 2mAOutput Signal: Electric frequency signal, high level 5V, low level 0VSensor Angle: Not more than 15 degreesDetection Distance: 2cm-450cmHigh Precision: Up to 0.3cmInput Trigger Signal: 10us TTL impulseEcho Signal : output TTL PWL signalQuantity: 3Mode of connection:VCCtrig(T)echo(R)GNDUse method:Supply module with 5V, the output will be 5V while obstacle in range, or 0V if not.The out pin of thismodule is used as a switching output when anti-theft module, and without the feet when ranging modulesNote :the module should be inserted in the circuit before been power, which avoid producing high levelof mis-operation;if not, then power againModule Working Principle:Adopt IO trigger through supplying at least 10us sequence of high level signalThe module automatically send eight 40khz square wave and automatically detect whether receivethe returning pulse signalIf there is signals returning, through outputting high level and the time of high level continuing isthe time of that from the ultrasonic transmitting to receiving. Test distance =(high level time * sound velocity (340M/S) / 2Note:This module is not suitable to connect with electric power, if you need to connect this module withelectronic power,then let the GND terminal of this module to be connected first,otherwise, it will affect thenormal work of the modulePackage Included:3 x HC-SR04 Ultrasonic Module amazon 60% off Shopping | Glasses, cameras, dress, cloth, watches, shoes, baby dress party dress
