Nice method and analysis. 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.

Krejci’s design, while affordable, offers an 8×8 resolution, which is the maximum output of the AMG8833 infrared sensor array. DIY Arduino thermal camera. Watch this video on YouTube.

Thermal cameras can cost well into the five-figure range if you’re buying high-resolution models with good feature sets. New models can be so advanced that their export and use is heavily con… ...

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, ...

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 ...

Temperature sensor uses Nickel RTD technology The Nickel RTD temperature sensor has a linear positive temperature curve with almost twice the sensitivity of a Platinum sensor and can be supplied in a ...

Traditionally, resistance-temperature-detector (RTD) sensor resistance is measured by applying a precision current source and measuring the developed voltage. This approach usually requires a ...
