Product description

Absolute Native Electronics Product Information
The HC-SR04 ultrasonic sensor uses sonar to measure distance to an object. It offers excellent range accuracy and stable readings in an easy-to-use package. It operation is not affected by sunlight or black material like Sharp rangefinders are (soft materials like cloth can be difficult to detect).
Module main technical parameters:
1.Working Voltage : 5V(DC)
2.Static current: Less than 2mA.
3.Output signal: Electric frequency signal, high level 5V, low level 0V.
4.Sensor angle: Not more than 15 degrees.
5.Detection distance: 2cm-450cm.
6.High precision: Up to 0.3cm
7.Input trigger signal: 10us TTL impulse
8.Echo signal : output TTL PWL signal

Mode of connection:
1.VCC
2.trig(T)
3.echo(R)
4.GND


The basic operation principle is below :
use IO port TRIG to trigger ranging. It needs 10 us high level signal at least
Module will send eight 40kHz square wave automatically, and will test if there is any signal returned.
If there is signal returned, output will be high level signal via IO port ECHO. The duration of the high level signal is the time from transmitter to receiving with the ultrasonic.
Testing distance = duration of high level*sound velocity(340m/s) / 2
You can use the above calculation to find the distance between the obstacle and the ultrasonic module.

    The output TTL provided is not of 5V in fact its around 1V. Thus its really difficult to interface it with microcontroller which runs on 5V. Can anyone say what is the amplitude at echo pin?

    If you have an arduino, just google hc-sr04 and you'll find everything you need to know to hook this up and get it working in about 2 minutes. The 4 pin design is easier to code than the 3 pin design where the signal and return are shared. Note that it's surprisingly large, so check the dimensions to be sure it will fit your project. Range is about 1 to 100 centimeters.
