DS9108

Concrete Temperature Monitor


Description

This product is a sealed plastic stick containing three DS1921G iButtons®. The iButtons are connected in parallel through metal plates that are spot-welded to the IO and GND contact, respectively. Two stranded wires protruding from the top end of the stick allow for a 1-Wire® reader/writer to make contact to the iButtons for setup and data retrieval. Electrically, the product is specified by the DS1921G data sheet, with the proper scaling (e.g., current ×3, capacitance ×3). The mechanical and thermal characteristics of the module are specified in this document.
