A Small Size Device Using Temperature Sensor Array

A small size device using temperature sensor array has been developed to measure the temperature distribution within a certain spatial,in which small thermistor array is using for temperature sensing.To minimize the adjacent sensor array mutual coupling and interference,an Isolated Drive Feedback measurement method has been proposed to detect the value of resistor in array.Finally,contact temperature sensing experiments were implement.Experimental results show that the small size device using temperature sensor array can identify the object shape with different temperature and it has good spatial resolution.
