DS1822Z+

DS1822 is a digital thermometer. It provides 9bit to 12bit centigrade temperature measurements and has an alarm function with NV user-programmable upper and lower trigger points. It communicates over a 1-wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor. In addition, this device can derive power directly from the data line (“parasite power”), eliminating the need for an external power supply. It has a unique 64-bit serial code, which allows multiple devices to function on the 1-wire bus; thus, it is simple to use one microprocessor to control many devices distributed over a large area. Applications that can benefit from this feature include HVAC environmental controls, temperature monitoring systems inside buildings, equipment or machinery, and process monitoring and control systems.
