Product Details

3Pcs HC-SR04 Ultrasonic Ranging Sensor Ultrasonic Module For Arduino

Description:

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 0.3cm
Input Trigger Signal: 10us TTL impulse
Echo Signal : output TTL PWL signal
Quantity: 3

Mode of connection:

VCC
trig(T)
echo(R)
GND

Use method:

Supply module with 5V, the output will be 5V while obstacle in range, or 0V if not.The out pin of this
module is used as a switching output when anti-theft module, and without the feet when ranging modules

Note :

the module should be inserted in the circuit before been power, which avoid producing high level
of mis-operation;if not, then power again

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. Test distance =(high level time * sound velocity (340M/S) / 2

Note:

This module is not suitable to connect with electric power, if you need to connect this module with
electronic power,then let the GND terminal of this module to be connected first,otherwise, it will affect the
normal work of the module
