Design of Sensor Experimental Unit of Internet of Things

In view of the characteristic of experiment course of Internet of things technologies,this paper discusses the preparation of the experimental unit including sampling and output of the data from temperature sensor. The unit is consisted of a U'tube heating device,a temperature- sensing device,signal amplification and filtering sampling device,AD conversion and control device,a display device and related software. The experiment unit covers a lot of experiment tasks of experiment teaching,which can obtain good teaching effect,and own strong practicability.
