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 includes:
1 x JSN-SR04T integrated ultrasonic ranging module.
