The performance of the ultrasonic sensor distance measuring module is stable,
measure the distance accurately. The module is with High precision, blind spots (3cm) super close. This module provides a full set of ranging process.
- Model: HC-SR04
- Color: Blue + Silver
- 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 3mm
- Mode of connection: VCC / trig(T) / echo(R) / GND
- Module Working Principle:
- Adopt IO trigger through supplying at least 10us sequence of high level signal
- The module automatically send eight 40khz square wave and automatically detect whether
receive the returning pulse signal
- 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
