This is the HC-SRultrasonic ranging sensor. This economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accurac. An 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 . Sonar uses the propagation of sound to detect objects.
Since sound waves travel farther in water than they do in air, sonar is preferred over other types of sensors like radar for this reason. This post is all about the Ultrasonic Sensor HC – SR04. The HC-SRultrasonic sensor uses sonar to determine distance to an object like bats do. It offers excellent non-contact range detection . We service OEMs, Distributors, and have an easy to use online store to purchase your sensors hassle free.
This sensor is perfect for any number of applications that require you to perform measurements between moving or stationary objects. The HC-SRis one of the lowest cost Sonar -based distance sensor options available (as low as $US). This sonar sensor measures the distance of an object using ultrasonic waves.

This paper presents a novel approach to mobile robot localization using sonar sensors. This approach is based on the use of particle filters. Each particle is augmented with local environment information which is updated during the mission execution. An experimental characterization of the sonar sensors. In a similar way to radar and sonar , ultrasonic transducers are used in systems which evaluate targets by interpreting the reflected signals.
For example, by measuring the time between sending a signal and receiving an echo the distance of an object can be calculated. Interested in ultrasonic? SICK ultrasonic sensors utilize the properties of sound. Objects and distances are determined precisely and with excellent background suppression and immunity to many types of foreign objects in the environment.
The output used – switching, analog, or both – is determined on the basis of your application requirements. Learn about the HC SRUltrasonic Sensor with the explanation on its working, pinout, pin description, 2D model and datasheet. Low cost compact ultrasonic sonar (distance measuring) sensor with up to 3. A host microcontroller circuit determines distance by triggering the US-1and then measuring the echo time indicated by the pulse width output of the sensor. Temperature compensatured for accurate ranging even on varying . Naturally, robotics applications are very popular but you’ll also find this product to.

The digital EVUltrasonic Sensor generates sound waves and reads their echoes to detect and measure distance from objects. It can also send single sound waves to work as sonar or listen for a sound wave that triggers the start of a program. Students could design a traffic-monitoring system and measure distances . A tutorial on how to connect the HC-SRultrasonic range sensor to the Raspberry Pi GPIO port so you can detect distances or range.
