| AN2163 demonstrates how a PSoC® 1 microcontroller can be interfaced with 1-wire® and Two-Wire (I2C) digital temperature sensors. |
This application note also illustrates how PSoC® 1 can be used for sensing temperature using a DS18S20 (1-wire digital temperature sensor) and a TMP75 (Two-Wire digital temperature sensor) along with the help of the attached example project.
Introduction
Monitoring temperature is a critical function in systems, such as Servers/CPUs, Battery charging/management, Consumer products, and Industrial controls, especially where there is a concern of loss in performance, reliability, and safety, due to variations in temperature. Several kinds of devices are available for sensing temperature such as thermistors, resistance temperature detectors (RTDs), thermocouples, and analog and digital output sensors.
