Abstract :
The design and micro-fabrication of a new combined temperature and conductivity sensor is presented. The temperature sensor is based on a thermistor and the conductivity sensor uses two planar electrodes built on a PCB board. Tests show the temperature sensor is accurate to 0.003degC and the conductivity sensor has an error within 2.7% for KCI concentration range of 0.2-1 Mol/L.
