Feature:
Main technical parameters:
1, Voltage: DC5V
2, Static current: less than 2mA
3, level output: high-5V
4, level output: the end of 0V
5, Sensor angle: not more than 15 degrees
6, Detection distance: 2cm-450cm
7, High precision: up to 1mm
8, Size:20*45*15mm
The wiring method: VCC, trig (control terminals), echo (receiver), GND
Module working principle:
(1) the IO trigger ranging, to at least 10us high level signal;
(2) module automatically send eight 40KHZ of square wave, automatic testing if it has any return signals;
(3) a signal to return to, through the IO output top level, the high level of the last time is
From the launch ultrasonic returned to time. Test distance = (high level time * sound velocity (340M/S)) / 2;
Operating voltage: DC 2.4V ~ 5.5V
Quiescent Current: 2mA
Working temperature: -20 ~ +70 degrees
Output: level or UART (jumper selectable)
