Product Description
DS18B20 Programmable Resolution 1-Wire Temperature Sensor
The DS18B20 is a digital thermometer providing 9 to 12-bit resolution temperature measurements. It features a unique 64-bit serial number, allowing multiple devices to be connected on a single bus for distributed temperature sensing. The device can be powered directly from the data line (2.5V to 5.5V) or via an external power supply. It offers a wide temperature measurement range of -55C to +125C (-67F to +257F) with an accuracy of 0.4C in the range of -10C to 70C. The DS18B20 includes user-definable non-volatile temperature alarm settings and robust electrostatic discharge protection.
