The Precision Temperature Data Logger is a dual-channel system built for high-accuracy monitoring with PT100 RTD sensors. Using Wheatstone bridge sensing, AD620 low-noise amplification, and a 24-bit ADS1256 ADC, it captures even the smallest resistance changes with exceptional resolution and stability. An STM32 microcontroller ensures precise acquisition and filtering, while USB-UART connectivity enables seamless data transfer to a PC. A Python-based GUI provides real-time visualization, digital filtering, and data logging for research and analysis.
Designed for versatility, this logger supports adjustable sampling frequencies, dual-channel operation, and robust calibration features for zero-point and gain adjustments. Its reliable performance makes it equally suitable for laboratory research, academic experiments, and industrial applications such as process monitoring, automation, and calibration setups requiring accurate, long-term temperature measurement.
