US-020 ultrasonic sensor


US-020 ultrasonic sensor distance measuring module detection range 2CM-700CM

If you are sourcing a ultrasonic ranging module,the US-020 is good choose.Its stable performance and high ranging accuracy make it a popular module in electronic market.Compared to the Shape IR ranging module,US-020 is more inexpensive than it.But it has the same ranging accuracy and longer ranging distance.

Ultrasonic sensor distance measuring module specification:

- Model: US-020
- Color: Green
- Working voltage : 5V(DC)
- Static current: Less than 3mA.
- Output signal: Electric frequency signal, high level 5V, low level 0V.
- Sensor angle: Not more than 15 degrees.
- Detection distance: 2cm~700cm.
- High precision: Up to 3cm
- 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
