Ultrasonic Module HCSR04 Distance Measuring Ranging Transducers Sensor DC 5V 2450cm

Supply module with 5V the output will be 5V while obstacle in range or 0V if not.The output pin of this module is used as a switching output when antitheft 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 nonoperation; if not then power again.

Features

Working Voltage : 5V(DC)
Static Current: Less than 2mA.
Output Signal: high level 5V low level 0V.
Sensor Angle: Not more than 15 degrees.
Detection Distance: 2cm450cm.
High Precision: Up to 0.3cm
Input Trigger Signal: 10us TTL impulse
Signal : output TTL PWL signal
Mode of connection: VCC trig(T) ech0(R) GND

Module Working Principle: 1. Adopt IO trigger through supplying at least 10us 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 (340M/S) / 2.
