DS18S20: High-Precision Digital Temperature Sensor | The Debug Store

Overview

The DS18S20 is a high-precision digital thermometer that offers accurate temperature measurements in a compact and versatile package. This 1-Wire device provides 9-bit Celsius temperature readings with ±0.5°C accuracy over a range of -10°C to +85°C, making it ideal for a wide variety of applications.

One of the key features of the DS18S20 is its unique 1-Wire interface, which requires only one data line (and ground) for communication with a microprocessor. This simplifies wiring and reduces system complexity. The sensor can even derive power directly from the data line, eliminating the need for an external power supply in many cases.

With an operating range of -55°C to +125°C, the DS18S20 is suitable for diverse environments. Each sensor has a unique 64-bit serial code, allowing multiple devices to function on the same 1-Wire bus. This makes it easy to create distributed temperature sensing systems across large areas.

The DS18S20 includes user-programmable nonvolatile alarm settings, enabling automated temperature monitoring and control. Its compact size and availability in both TO-92 and SO packages provide flexibility for various installation requirements.

Ideal for HVAC systems, industrial controls, consumer products, and process monitoring, the DS18S20 offers a reliable and cost-effective solution for precise temperature measurement in a wide range of applications.
