A genuine Maxim sourced DS18B20+ One Wire Digital Temperature Sensor. The DS18B20+ is the perfect low-cost solution for a range of Raspberry Pi and Arduino temperature control and data-logging projects! The DS18B20+ measures temperature in degrees Celsius with 9 to 12-bit precision and includes an alarm function with nonvolatile user-programmable upper and lower trigger points. Sensing range is -55C to 125C (accurate to ±0.5°C over the range of -10°C to +85°C), 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 Raspberry Pi's 3.3V power line. Note: Image is a representation and may show another brand, however we only ship authentic Maxim sensors.
