This US-020 ultrasonic module can realize 2 ~ 700cm of non-contact ranging function, has 5 V of wide
voltage input range, static power consumption is less than 3mA. Their own temperature sensor will
revise the ranging and has many communication modes like GPIO, just like watchdog inside, very stable
and reliable.

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

Ultrasonic sensor distance measuring module Wire connecting direct: 

1. 5V Supply 
2. Trigger Pulse Input
3. Echo Pulse Output
4. GND

Ultrasonic sensor distance measuring module packing include:

 1 x US-020 ultrasonic sensor distance measuring module
