GENERAL DESCRIPTION  
FEATURES  
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/write 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.  
ƒ
Three DS1921G networked to monitor temperate  
at the top, bottom and center of the stick  
Connects to 1-Wire reader/writer through color-  
coded 18 AWG (1 mm Ø) stranded wires with ½  
inch (1.3 cm) stripped ends
