OVERVIEW: A wireless temperature sensor employing 8 three wire PT100 RTDs transmitting the acquired data using Bluetooth. The aim of this project was to measure and wirelessly transmit temperature ...

This post also details the math behind the circuit design and should be a good read. The Arduino sketch does not rely on PT100RTD library mentioned above, and is much simpler, but note the circuit ...

Arguably, this advice applies to the circuit design used in many RTD sensors that quietly and efficiently measure temperature in industrial manufacturing facilities worldwide. However, to meet the ...

A PT100 probe is a platinum resistance thermometer with a nominal resistance of 100 Ω at a temperature of 0 ° C. Its features are regulated by the IEC 751 (EN 60751) standard. This type of temperature ...

For example, a Pt100 RTD has a resistance of 100 Ω at 0 °C. An accuracy of +/- 0.15 °C at 0 °C is typical, but accuracies down to +/- 0.03 °C are available.

Abstract: This article reviews the basic characteristics of common temperature sensors, describes the RTD PT100 temperature transducer, and explains a simple analog approach for linearizing and ...

Designing an analog circuit can be a frustrating experience, as noted by Nick Cornford in his Design Idea (DI), “DIY RTD for a DMM.”With a fortnight’s struggle, I completed the design of 4 mA to 20mA, ...
