HC-SR04 Ultrasonic Sensor Module Distance Measuring Sensor Module ((((3Pcs))))
HC-SR04 Ultrasonic Sensor is a device that can measure the distance to an object by using sound waves. It measures distance by sending out a sound wave at a specific frequency and listening for that sound wave to bounce back. By recording the elapsed time between the sound wave being generated and the sound wave bouncing back, it is possible to calculate the distance between the sonar sensor and the object.Themodule works:(1) IO trigger ranging to at least 10us high signal;(2) module automatically sends eight 40kHz square wave, automatically detect whether a signal return;(3) the signal to return, a high IO output, high duration ofUltrasonic time from launch to return. Test distance = (time high speed of sound (340M / S)) / 2;Technical Specification：Power Supply :+5V DCQuiescent Current : 3mAWorking Current: < 5mAEffectual Angle: <15°Ranging Distance : 2cm - 450 cmResolution : 0.3 cmMeasuring Angle: 30 degreeNote: The module should be inserted Fortunately, the circuit board re-energized, and avoid the high malfunction, if they have re-energized before they solve.
