Waterproof Ultrasonic Sensor Module

Description

Lead length 2.5M

Product Features:
1, Small size, easy to use;
2, Low voltage, low power consumption;
3, High measurement accuracy;
4, Strong anti-interference;
5, Integrated closed water tight design with a line probe for wet, harsh measurement occasions.

Applications:

Distance measurement, obstacle avoidance, automatic control, security, industrial control, teaching and research

The basic working principle:
(1)Start measurement by Using IO TRIGTrigger  to at least 10us high-level signal;
(2)The module automatically sends 40khz square wave, automatically detect whether there is signal return;
(3) If there is a signal return via IO ECHO Output .High duration is the time from the launch of the ultrasound to the return.Test

distance calculation= (high time * sound speed (340M / S)) / 2;
