I'm trying to reverse engineer an aging datalogger. Before building my schematic, I would like to identify all the components. There is one component that I can't seem to identify after many hours searching the web. (T1). Can someone identify what it is please?
Thanks in advance.
P.s How do you post a picture, sorry I'm new to the site.
Please find link below to the picture on Imgur.
