Temperature Sensor- 1W

The digital thermometer provides 9-bit to 12-bit Celsius temperature measurements. communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central micro­processor.
In addition, can derive power directly from the data line (“Parasite Power”), eliminating the need for an external power supply.

Has a unique 64-bit serial code, which allows multiple sensors to function on the same 1-Wire bus. Thus, it is simple to use one microprocessor to control many sensors 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.
