Ultragarsinis atstumo matuoklis HC-SR04
HC-SR04 Ultrasonic/Sonar Distance Sensor Module
- Operating 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
- VCC
- trig(T)
- echo(R)
- GND
Note: the module should be inserted in the circuit before been power.
Module 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: when installing, connect the GND terminal first, otherwise, the module may get damaged.
