This 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.
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
