This small module is capable of measuring the distance within the range of 2cm – 400cm. The module has a built-in small microprocessor which does all the heavy lifting of managing the ultrasonic sensors. Our ultrasonic sensors, like many others, use a single transducer to send a pulse and to receive the echo. Weight [g] ~ 8 to 10. Let Raspberry Pi’s communicate with each other per 433MHz wireless signals. Each HC-SR04 module includes an ultrasonic transmitter, a receiver and a control circuit. Ultrasonic transducers and ultrasonic sensors are devices that generate or sense ultrasound energy. Martin McMerkin 12-17-2017 at 20:42. In this instructable, I will show you how to interface a Waterproof Ultrasonic Sensor Module (JSN SR04T - 2.0) with the Arduino board. The Ultrasonic Senor uses Ultrasonic waves to determine the distance of an object like Bats, hence it can be used as a distance measuring sensor. An optical sensor has a transmitter and receiver, whereas an ultrasonic sensor uses a single ultrasonic element for both emission and reception. The acoustic wave signal is an ultrasonic wave traveling at a frequency above 18kHz. It is a really accurate sensor, it can measure upto 3mm. This sensor calculates the time and direction of ultrasound in the air by sending a short audio pulse at a frequency higher than the human hearing range and receiving it after reflection of the surface of the object. This post is all about the Ultrasonic Sensor HC - SR04. They were once used for mapping of ships in sea and detection of broken/faulty parts in mechanical systems. 49. This is similar to how radar measures the time it takes a radio wave to return after hitting an object. Next article. As you can see the illustration below the sensor trigger pin is connected to D1 which is pin 5 in Arduino Board, and the ECHO is connected to D2 which is pin 4 in Arduino Board.
