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 isn’t about connecting a temperature sensor in your Arduino. ... The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.

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, ...
