Ultrasonic transducer
[HC-SR04]

Ultrasonic transducer
Ultrasonic sensor HC-SR04 by 1. This module performance is stable, measure the distance accurately.
2. The technical values:
Voltage: DC 5V
Current <2 mA
Measuring angle: up to 15 degrees
Sensing distance: 2cm-450cm
Highly accurate: 2mm
Connection: VCC, trig (missile side), echo (receiving end), GND
3.Moduli works:
By triggering a 5 V signal at least 10us
the module automatically sends eight 40kHz pulse, received echo
Distance = (* high level speed of sound (340m / s)) / 2
