The sensor is a 6-pin CF sensor , 3 pins (gnd, 5V and analog output). Connecting them directly to the Arduino Pro mini and measuring the analog output to ground gives 4.98 V. so I connected a 10k resistor in parallel with the analog output and used the math formular ((5./1023.) * analogRead(A0)). I got 0.67 volts on the serial monitor when no pressure is applied, this value also corresponded with my multimeter value so I knew it was working fine.Now I need the sensor to be more than 20metres away from the controller but the value is no longer changing on the serial monitor rather it keeps showing 0.42 volts no matter how much pressure I apply
