  • 高精度温度测量铂电阻温度探测器(PRTDs)和​​ADC

    Abstract: Many modern industrial, medical, and commercial applications require temperature measurements in the extended temperature rangewith accuracies of ±0.3°C or better, performed with reasonable cost and often with low power consumption. This article explains how platinumresistance temperature detectors (PRTDs) can perform measurements over wide temperature ranges of -200°C to +850°C, with absolute accuracyand repeatability better than ±0.3°C, when used with modern processors capable of resolving nonlinear mathematical equation quickly and costeffectively. This article is the second installment of a series on PRTDs. For the first installment, please read application note 4875, "High-Accuracy Temperature Measurements Call for Platinum Resistance Temperature Detectors (PRTDs) and Precision Delta-Sigma ADCs."

  • 智能照明控制器测量环境光线

    Abstract: This application note explains how to design an intelligent lighting controller that senses and measures the ambient lightlevel with an ambient light sensor (ALS). Equipped with a real-time clock (RTC), the controller also knows when to turn lighting on oroff at specified times. The system presented in this document can be used to control all luminaires that are mains-supply operated.Controller software is also provided in hex format.

  • 确定任务参数的温度记录仪

    Logger iButton devices have gained a lot of popularity with researchers. Although free evaluation software is easy to use and welldocumented, the choices and inputs that need to be made can sometimes be challenging. This application note explains technicalterms that are common with temperature logger iButtons and how they relate to each other. Additionally, it presents an algorithm tohelp users choose the necessary input parameters, including the sample rate based on a user's needs and the available memory tostore the data.

  • 陶瓷电容器的温度和电压的变化

    Abstract: The reality of modern, small form-factor ceramic capacitors is a good reminder to always readthe data sheet. This tutorial explains how ceramic capacitor type designations, such as X7R and Y5V,imply nothing about voltage coefficients. Engineers must check the data to know, really know, how aspecific capacitor will perform under voltage.
