HC-SR04 User Guide Part 1 Ultrasonic Introduction 1. 1 Ultrasonic Definition The human ear can hear sound frequency around 20HZ ~ 20KHZ, and ultrasonic is the sound wave beyond the human ability of 20KHZ . 1.2 Ultrasonic distance measurement principle Ultrasonic transmitter emitted an ultrasonic wave in one direction, and started timing when it launched. Ultrasonic spread in the air, and would return immediately when it encountered obstacles on the way. At last, the ultrasonic receiver would stop timing when it received the reflected wave. As Ultrasonic spread velocity is 340m / s in the air, based on the timer record t, we can calculate the distance (s) between the obstacle and transmitter, namely: s = 340t / 2, which is so- called time difference distance measurement principle The principle of ultrasonic distance measurement used the already-known air spreading velocity, measuring the time from launch to reflection when it encountered obstacle, and then calculate the distance between the transmitter and the obstacle according to the time and the velocity. Thus, the principle of ultrasonic distance measurement is the same with radar. Distance Measurement formula is expressed as: L = C X T In the formula, L is the measured distance, and C is the ultrasonic spreading velocity in air, also, T represents time (T is half the time value from transmitting to receiving ). 1 1.3 Ultrasonic Application Ultrasonic Application Technology is the thing which developed in recent decades. With the ultrasonic advance, and the electronic technology development, especially as high-power semiconductor device technology matures, the application of ultrasonic has become increasingly widespread: Ultrasonic measurement of distance, depth and thickness; Ultrasonic testing; Ultrasound imaging; Ultrasonic machining, such as polishing, drilling; Ultrasonic cleaning; Ultrasonic welding; Part 2 HC-SR04 Ultrasonic Module Introduction 2.1 Product Features Stable performance Accurate distance measurement High-density Small blind Application Areas: Robotics barrier Object distance measurement Level detection Public security Parking detection 2 2.2 Product Image 2.3、Module pin definitions Types HC-SR04 Pin Symbol VCC Trig Echo GND Pin Function Description 5V power supply Trigger pin Receive pin Power ground 2.4、Electrical parameters Electrical Parameters Operating Voltage Operating Current Operating Frequency Farthest Range Nearest Range Measuring Angle Input Trigger Signal Output Echo Signal Dimensions HC-SR04 Ultrasonic Module DC-5V 15mA 40KHZ 4m 2cm 15 Degree 10us TTL pulse Output TTL level signal, proportional with range 45*20*15mm 3 2.5 Module operating Principle Set low the Trig and Echo port when the module initializes , firstly, transmit at least 10us high level pulse to the Trig pin (module automatically sends eight 40K square wave), and then wait to capture the rising edge output by echo port, at […]
