+Python simulation of an IR thermometer demonstrating real-world sensor behavior including noise, drift, outliers, and signal processing techniques (moving average filter & outlier rejection).
+
+A Python-based simulation of a Digital Infrared (IR) Thermometer for body temperature measurement. 
+This project demonstrates how real-world environmental factors affect temperature readings over a 
+60-second period, including:
+
+- Random measurement noise (Gaussian distribution)
+- Temperature drift (-0.1°C/min)
+- Emissivity mismatch bias
+- Occasional outliers and spikes
+
+The simulation implements signal processing techniques to improve measurement accuracy:
+- Moving average filter (window size: 5)
+- Statistical outlier rejection (3σ threshold)
+
+Based on the Stefan-Boltzmann Law for infrared radiation, this project visualizes the difference 
+between raw sensor data and processed measurements, demonstrating the importance of signal processing 
+in real-world sensor applications.
+
+Developed as part of the "Artificial Intelligence for Industrial Applications" program at 
+OTH Amberg-Weiden.
