О товаре

This performance of the ultrasonic sensor distance measuring module is stable and accurate; The module is with High precision blind spots (3cm) super close

This module provides a full set of ranging process; Holder Thickness: 2


1mm; inner diameter: 16mm; fasten hole: 3

8mm; Working voltage: 5V(DC); 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
