Signal conditioning circuit of one sensor. The circuit was supplied with a constant voltage of 10 V (V+) to increase the sensor dynamic range and to enhance the sensor resolution. The circuit was modified appropriately, whereby, the sensor was connected in series with a 68-kΩ resistor (R), and a non-inverting impedance converter was implemented between the circuit and the analog digital converter (ADC).
