Ultrasonic Distance Sensor, Ping Sensor, Perfect for Aduino

This Distance Sensor will soon become essential for your robotic applications. Indeed, with this sensor, it is possible to know the exact distance of an obstacle in the sonar field of view. The cleverness of your robot will use a sensitive sensor similar to the one bats use to know their position. With advanced programming, you can design compensators in order to perfectly control your motors according to the obstacle's distance.

Key Features

Model: HC-SR04

Working voltage : 5V(DC)

Static current: Less than 2mA.

Output signal: Electric frequency signal, high level 5V, low level 0V.

Sensor angle: Not more than 15 degrees.

Detection distance: 2cm~450cm. High precision: Up to 3mm

Mode of connection: VCC / trig(T) / echo(R) / GND Module

Working Principle: Adopt IO trigger through supplying at least 10us sequence of high level signal The module automatically send eight 40khz square wave and automatically detect whether receive the returning pulse signal If there is signals returning, through outputting high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving
