Hey guys, i found a intresting project for water monitoring system.
https://www.practicalarduino.com/projects/water-tank-depth-sensor
Previously i was using Water proof POT acting as a float valve and sending that POT voltage to ADC, that Project didnt last long because in summer temperature is quite hot (40 degree )and the the tank was black in color, the POT gone mad after 3 months. any ways that was 2 years back, the tank was at 10 meter distance from the circuit.
Now in my recent home, tank is 40 meters away. 25 meter to the roof and 15 meters horizontal distance.
I am going to use the pressure sensor as in the link above( tank is now white in color by the way ). so if i am going to use PIC's ADC then what about the noise in that wire, sensor got 4 pins, so 4 pairs of wire is needed. 2nd option is to go fro RF module or Zigbee (haven't work on both of them ). a normal 4 paired telephone wire would be cheap but it got 1 ohms resistance per meter ( i think). So what option would be good?
Resolution would be 1, from 0 to 100 %.
