The ⦠Open the Arduino IDE software on your computer. This system consists of ultrasonic sensor with microcontroller and display. This HC-SR04 sensor and Arduino circuit also can be used as a touchless doorbell or distance measuring tool. Distance Calculation with Ultrasonic Sensor. How Ultrasonic Sensors Work. The HC-SR04 ultrasonic sensor is based on the ⦠Coding in the Arduino language will control your circuit. The device is based on the microcontroller AVR ATMEG⦠Ultrasonic Distance Sensor (Simplified Schematic: All Connections and Decoupling Not Shown) CIRCUIT DESCRIPTION Ultrasonic Measurement Theory Figure 2 shows a typical ultrasonic distance measurement system. In circuit connections Ultrasonic sensor moduleâs âtriggerâ and âechoâ pins are directly connected to pin 18(A4) and 19(A5) of arduino. In this project, we will discuss how to measure distance using ultrasonic sensor HCSR04 and Arduino with circuit diagram and Arduino code. This is the ultrasonic distance detector or sonar ranging system which can be used for general purpose. Sound travels through the air with almost speed 344m/s (1129ft/s) and this speed is mutiplied with the total time (sending and receicving) of sound wave. Either follow the few steps below or refer to the circuit diagram on how to assemble this super easy circuit. The connection to the Ultrasonic sensor and LCD are standard and well documented. The interfacing diagram ⦠In this project, we will discuss how to measure distance using ultrasonic sensor HCSR04 and Arduino with circuit diagram and Arduino code. The sensor works on the same principles of a radar system, which converts electrical energy into acoustic waves and vice versa. These small modules are available starting at 1-2 bucks and can measure the distance up to 4-5 meters by ultrasound and are suprisingly accurate . The basic principle behind the working of ultrasonic sensor is to note down the time taken by sensor to transmit ultrasonic beams and receiving the ultrasonic beams after hitting the surface. The working of the transmitter can be checked by converting the 40kHz signal to 4kHz to bring it in the range of audible sound. The prototype circuitry was wired on a perforated circuit board which forma shield for the Arduino uno. If there is some movement in the area covered by the ultrasonic emission the signal that is reflected back to the receiver becomes distorted and the circuit is thrown out of balance. By using this receiver circuit, the 40kHz transmitter circuit can be quickly tested. Distance= (Time x Speed of Sound in Air (340 m/s))/2 Circuit Diagram The circuit diagram for Ultrasonic distance measurement using Arduino is given below.
