Ultrasonic Distance Sensor Module – HC-SR04

Ultrasonic Distance Sensor
provides very short (2CM) to long-range (4M) detection and ranging. The
sensor provides precise and stable non-contact distance measurements
from about 2cm to 4 meters with very high accuracy. It can be easily
interfaced to any microcontroller.

Description:

This
ultrasonic sensor module can be used for measuring distance, object
sensor, motion sensors etc. High sensitive module can be used with
microcontroller to integrate with motion circuits to make robotic
projects and other distance, position & motion sensitive products.

The
module sends eight 40Khz square wave pulses and automatically detects
whether it receives the returning signal. If there is a signal
returning,  a high level pulse is sent on the echo pin. The length of
this pulse is the time it took the signal from first triggering to the
return echo.
