Ultrasonic sensor hcsr04

This economical sensor provides 2cm to 400cm of non-contact measurement functionality with a ranging accurac. It has also been used in turret . The Module automatically . It works by sending sound waves from the transmitter, which then bounce off of an object and then return to the receiver. You can determine how far away something is by the time it takes for the sound waves to get back to the sensor. At RobotShop, you will find everything about robotics.

A ruler that measures centimeters (or use the serial monitor). It generates high frequency sound and calculate the time interval between the sending of signal and the receiving of echo. Therefore, ultrasonic sensor can be used to measure distance.

It operation is not affected by sunlight or black material like Sharp . It offers excellent non-contact range detection with high accuracy and stable readings in an easy-to-use package. This module offers excellent range accuracy and. IF the signal back, through high level , time of high output IO duration is . Run the sketch and open a serial.

Waveshare Electronics, China. Ultrasonic Sensor - HC-SRfrom SparkFun. One of the most useful sensors for robotics projects is a distance sensor. With a bit of care and an additional component it can also be used as a measurement device.

And its range is from 2cm to 3m (with nominal errors). Another low cost ultrasonic range finder. Though it is not as easy as Maxbotic EZ- it offers quite satisfy result.

HC - SRultrasonic sensor uses sonar to determine distance to an object like bats or dolphins do. This ultrasonic sonar sensor allows to measure distances from 2cm to 400cm with an accuracy up to 3mm. Minimalist library for ultrasound module to Arduino.

Work with ultrasound module in a simple and light way. Compatible with the modules HC - SR, Ping))) and Seeed Studio sensor.
