Abstract

Aiming at characteristics of crop nutrient solution conductivity

a conductivity sensor and its measurement system based on principle of electromagnetic induction and combined with electrode are designed.The structure and working principle of the combined conductivity sensor are described. Also

the optimal parameters of the sensor are selected. Aiming at influence of temperature on conductivity

a software automatic temperature compensation method is proposed

and calibration of the sensor is carried out by using standard conductivity solution. Experimental results show that the relative error of measured conductivity sensor is less than1 %

and it can meet requirement of measuring crop nutrient solution conductivity.
