Description
The DS18B20 Waterproof Temperature Sensor is a high-precision digital sensor designed for reliable temperature measurement in harsh or wet environments. Encased in a stainless steel waterproof probe, it delivers accurate temperature readings without the need for an external ADC.
Using the 1-Wire protocol, the sensor requires only one data line to communicate with a microcontroller. This allows multiple DS18B20 sensors to be connected on the same bus, making it a preferred choice for distributed and multi-point temperature monitoring systems.
Its compact design and durable encapsulation make it suitable for immersion in liquids, environmental monitoring, and industrial applications.
