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 o C ÷ 29 o C, and tested in outdoor conditions, exhibiting a maximum uncertainty of 1 o C 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.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
