| Abstract: | A new type intelligent measuring system for measuring water content based on Bluetooth technique and capacitance sensor is proposed. Bluetooth technique,C/U convert circuit,U/f convert circuit and temperature compensating design are used. C/U convert circuit consists of sine signal generation circuit,buffer circuit and convert circuit.The parts selected is exact and works steadily.The experimental results show that the system can display precisely with linearity scale in the full scale(0%~100%). |
