  • Ultrasonic HC-SR04 distance measuring transducer sensor
  • HC-SR04 consists of an ultrasonic transmitter, receiver, and a control circuit. When triggered it sends out a series of 40KHz ultrasonic pulses and receives echo from an object.
  • Power supply: 5V DC; quiescent current: less than 2mA; effectual angle: less than 15°; distance: 2cm500cm; resolution: 0. 3 cm~
  • Package Content: 5pcs HC-SR04 with a little gift

ELEGOO 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.

Ultrasonic Sensor HC-SR04 is great for all kinds of projects that need distance measurements, avoiding obstacles as examples. HC-SR04 provides 2cm-400cm non-contact measurement function, the ranging accuracy can reach to 3mm. The modules include ultrasonic transmitters, receivers, and control circuits.

Operating Principle of Ultrasonic Sensor

As the name indicates, ultrasonic sensors measure distance by using ultrasonic waves. The sensor head emits an ultrasonic wave and receives the wave reflected back from the target. Ultrasonic Sensors measure the distance to the target by measuring the time between the emission and reception. The distance can be calculated with the following formula: Distance L = 1/2 × T × C where L is the distance, T is the time between the emission and reception, and C is the sonic speed. (The value is multiplied by 1/2 because T is the time for the go-and-return distance.)

For Arduino Project with Ultrasonic Sensor

Elegoo Ultrasonic Sensor HC-SR04 is inexpensive and easy to use since we will be using a Library specifically designed for this sensor, which can be downloaded from elegoo.com. To use it for Arduino projects you would need an ELEGOO UNO R3 controller board.
