In this paper we present a low-cost system for temperature measurement based on a fibre Bragg grating and a narrow bandwidth fixed-wavelength laser. The system has been calibrated in the range 7 oC÷29 oC, and tested in outdoor conditions, exhibiting a maximum uncertainty of 1 oC over a 3 days. This performance, together with features such as small form factor and intrinsic fire safety, makes it a possible solution for continuous monitoring of cultural heritage infrastructures and artifacts.
