Abstract: The environment monitor system is a vital component of contemporary large astronomical telescopes for better images and efficient scientific outputs. This paper focuses on the design and realization of a data acquisition system for telescopes’ environmental temperature. The design mainly features USB technique for data speedy transfer and control with low power consumption. The research practice has particularly provided valuable experience for the design of environmental monitor system of the ongoing large sky area multi-object fiber spectroscopic Telescope (LAMOST), which is one of the large scientific projects in China
