I’m using sensors #2578 and #2579, and they’re wired correctly (VCC, GND, OUT, ENABLE).
Yet the OUT output remains always at low state, and the red LED stays on, regardless of the distance.
I’ve tried five different #2578 and #2579 sensors.
I’ve set the frequency to exactly 38 kHz.
I don’t understand.
(All my sensors are brand new.)
Hello.
Can you post some pictures of your setup that show all of your connections and the orientation of your sensors in your application? Also, please include some close-up pictures of the sensor boards from a few different angles. What are you using to power the sensors, monitor the OUT pin, and control the ENABLE pin?
