Product Details
✓HC-SR04 Ultrasonic Sensor：This is a device that can use sound waves to measure the distance of an object. It measures distance by emitting a sound wave of a specific frequency and listening to the bounce of that sound wave. The distance between the sonar sensor and the object can be calculated by recording the time elapsed between the generation of the sound wave and the bounce of the sound wave
✓Working Voltage: 5V DC；Quiescent current: less than 2mA
✓Ranging Distance：2cm - 450 cm；High precision: 0.3 cm
✓Effectual Angle: <15°
✓Test mode ：Test distance = ((Duration of high level)*(Sonic :340m/s))/2
