Description

Ultrasonic sensor distance measuring module

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 0.3cm

Connections are: 1-VCC, 2-trigger (control side), 3-echo (receiving end), 4- GND

Usage:

(1) The IO trigger signal should be at least 10us;
(2) the module automatically sends eight 40khz square wave, automatically detects whether a signal returns
(3) a signal back, through the IO of a high output, high duration is
Ultrasonic time from launch to return. Test distance = (time * High speed of sound (340M / S)) / 2;

This module provides a full set of ranging process:
