Re: JSN-SR04T (distance sensor) Reliability Issue Fix?

I read over this topic but did not found my project scenario! Asking people who extended the line of the senzor

I have a project installing this sensor on some trucks, so the coax cable is arround 16 meters long.

5 Trucks installed so far....3 of them work fine, 2 of them always return 23-22cm.

Checked the wirring of the coax to be continuos, no ripped cable or anything.

Need to mention that the ones that are working I turned the knob on the sensor for like middle of distace

Any ideas how I can change more of the knob in order to get it working...or some info on how I can fix it?

Update and problem fixed!

For everybody that will encouter this, the problem was at the sensor side because of the folder of the sensor! We created some metal brackets for it and they where exactly the same diameter. The fact that the mount squeezed the sensor made it return the lowest value.

Just needed to adjust the hole and everything was ok!
