Introduction

DC 5V Ultrasonic module HC-SR04 distance measuring transducer sensor for arduino.
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
Mode of connection:VCC, trig(T), echo(R), GND
The basic operation principle is below:
1.use IO port TRIG to trigger ranging. It needs 10 us high level signal at least
2.Module can send 8 pro 40 kz square wave automatically, and will test if there is any signal returned.
3.If there is signal returned, output one high level signal via IO port ECHO. The duration of the high level signal is the time from transmitter to receiving with the ultrasonic.
