JSN-SR04T 2.0 Cable length

Other Hardware Sensors
1

Sorry for the basic question. This is my first project for real world application.

I'm using a JSN-SR04T 2.0 with ESP32 on Arduino IDE to make a system for monitoring water level in multiple tanks and automatically fill them when empty. On the breadboard everything seems to be working perfectly. It is now time to design and get the PCB printed.

In real world application the distance between the microcontroller and the water tank is about 40-50 feet. Whereas the ultrasonic sensor came with a cable length of 5 feet. I'm planning on cutting the cable and extending it between the sensor and the breakout board that comes with it. Breakout board will be directly connected to PCB at a distance of 50 feet from the actual sensor.

My question is- is there anything I need to keep in mind like supplying higher voltage to the sensor or add anything extra to the PCB in order to compensate for this distance?

Thanks in advance

Be sure to test everything for functionality BEFORE modifying anything!

40-50 ft that's 15 meters, a long antenna you create there.
Noise may become an issue. A 100 nF cap to GND on both ends of the signal wire would be a good idea, as would be extra caps between Vcc and GND on the sensor's side. Shielded cable is another way to limit noise - connect the shield to GND but only on one end.
Don't increase the voltage to the sensor unless you want to try and break stuff.

Hello,

you can't extending the cable !
I'll tried, and after it's not works very well.
