Hi Everyone !
I have a question about the Ultrasonic sensor.
I have a water-box and I’d like to measure how fill is using the HC-SDO4 sensor with Arduino
It is all set and in my protoboard the sensor works well, but when I try to connect to sensor through a 4way wire it is not working.
The water-box (and the sensor is inside in a dry place of course) is 4 meters from the Arduino, wired connected.
My question is, Does have any limitation in distance to connect the sensor through a wire?
If yes, what you suggest me to do? How can I send the signal and receive the echo to Arduino in 4 meters of distance?
Thank you!
