The DS18B20+ is the perfect low-cost solution for a range of and temperature control and data-logging projects! The DS18B20+ measures temperature in degrees Celsius with 9 to 12-bit and includes an alarm function with nonvolatile user-programmable upper and lower trigger points. Sensing range is -55C to 125C (accurate to ±0.5℃ over the range of -10℃ to +85℃), and each sensor has a unique 64-bit serial number hard-programmed enabling the use of a number of sensors on a single data bus.
The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central microprocessor, and can be powered on the 's 3.3V power line.
