Product Description
Product Overview
The DS18B20U is a digital temperature sensor offering 9 to 12-bit temperature measurements with user-configurable high and low alarm thresholds. It communicates via a single-wire interface and can operate in both external power and parasitic power modes. Multiple DS18B20U devices can be controlled by a single microcontroller for large-area temperature monitoring. Its wide operating voltage range, low power consumption, and single-wire interface make it ideal for various temperature control systems.
