This paper proposes a scheme for wide-range precision measurement of the environmental temperature in a double-cavity optomechanical system. This system consists of an optomechanical cavity coupling to the other cavity via photon tunneling interaction. Bycontrolling the tunnelling strength between the two cavities, double optomechanically induced transparency (double OMIT) effect is observed in the homodyne spetra of the outfield. It is shown that the central peak value depends linearly on the environmental temperature. Based on this linear relationship, the environmental temperature can be inferred from the central peak value of the output homodyne spectrum. This scheme is robust against mechanical decay and it shows high sensivity over a wide temperature range.
