Product description
DS18B20+ Programmable Digital Temperature Sensor with 1-Wire Interface. The DS18B20+ is a digital temperature sensor from Analog Devices (formerly Maxim Integrated) that provides temperature measurements in Celsius with a programmable resolution between 9 and 12 bits. It is designed to communicate via a 1-Wire interface, requiring only a single data line (plus ground) for communication with a microcontroller.
