Concrete Temperature Monitor

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.

Applications

* Concrete Maturity Monitoring

* Three DS1921G networked to monitor temperate at the top, bottom and center of the stick

* Connects to 1-Wire reader/writer through colorcoded 18 AWG (1 mm Ø) stranded wires with ½ inch (1.3cm) stripped ends

* Electrically compatible to the DS1921G Thermochron iButton (3 in parallel)

* Sealed against liquid intrusion

* Module position information stored in DS1921G memory
