The Thermo 2 Click Board™ is a measurement accessory board that includes DS1825, a programmable resolution 1-wire digital thermometer. The digital thermometer provides 9 to 12-bit centigrade temperature measurements and communicates over a 1-Wire bus.
The DS1825 chip has a unique 64-bit serial code, which allows the user to connect multiple DS1825s to function on the same 1-Wire bus.
