How can I extend the wires of my soil moisture sensor without dropping analog output voltage?
My control box is 15 meters from the plants. I also have my 5v power supply for my sensor. I have 2 sensors.
Specification for control box:
Power supply: 3.3v or 5v
Output voltage signal: 0~4.2v Current: 35mA
Analog output (Blue wire)
GND (Black wire)
Power (Red wire)
