traffic control;

security, industrial control;

Artificial intelligence, teaching and research

The basic working principle:

(1)Using IOTRIGTrigger ranging, to at least 10us high-level signal;

(2)The module automatically sends8A 40khz square wave, automatically detect whether there is signal return;

(3) There is a signal return via IOECHOOutput oneAHigh, high duration is the time from the launch of the ultrasound to the return.Test distance = (high time * sound speed (340M / S)) / 2;

Package Included:

1X JSN-SR04T integrated ultrasonic ranging module
