Ultrasonic Module HC-SR04 Distance Measuring Ranging Transducer Sensor DC 5V 2-450cm

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
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 misoperation;if not, then power again.

Module Working Principle:

1. Adopt IO trigger through supplying at least 10us sequence of high level signal.
2. The module automatically send eight 40khz square wave and automatically detect whether receive
the returning pulse signal.
3. 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

Package Included:

1 x HC-SR04 Ultrasonic Module Distance Measuring Transducer

    today i have recieved it,it’s good and work perfectly,store recomended.but the hole of the bracket is bit larger than ultrasonic sensor.it has good accuracy also. ඒක හොදට වැඩ කරනව,සෙලර්ව රෙකමන්ඩ් කරනව. හැබයි බ්‍රැකට් එකේ සිදුර ටිකක් සෙන්සර් එකට වඩා ලොකු වැඩියි.හොද නිරවද්‍යතාවයකුත් තියනව

    There was a parcel comparatively with other goods for a long time, but in its period lay down. Flux does not wash places. In general, everything is fine

    The sensor is attached to the yak in description. In the meantime, do not go forward with the vicrist such for visa reviews for help Arduino and other modular devices. In the reception I buy the podvnistu zadoveniy. They delivered to Ukraine for 3 types.
