Introduction
The objective of this project is to design, build, and validate a precision thermocouple-based temperature measurement system using the Seebeck effect. The system converts the extremely small thermoelectric voltage generated by a thermocouple into accurate, real-time temperature data. Unlike thermistors or integrated circuit temperature sensors, thermocouples are capable of:
- Operating over a very wide temperature range
- Withstanding harsh and high-temperature environments
- Responding rapidly due to low thermal mass
However, the output signal from a thermocouple lies in the microvolt range, making accurate measurement challenging. This project addresses that challenge by implementing:
- A low-noise instrumentation amplifier
- Cold junction compensation (CJC)
- Microcontroller-based digitization, linearization, and calibration
