Description
The DS18B20 is a digital temperature sensor designed for accurate temperature measurement using a 1-Wire communication interface. It supports 9-bit to 12-bit resolution and operates over a wide temperature range from -55 C to +125 C. The sensor features a stainless steel waterproof probe with a 100 cm cable, enabling reliable operation in humid or liquid environments. With a unique 64-bit serial code and optional parasite power mode, it allows multiple sensors to be connected on a single data line. It is suitable for embedded systems, industrial monitoring, and environmental sensing applications.
