⚙️ Working Principle
🔥 Infrared Thermopile Sensing
Detects infrared radiation emitted by a surface
Thermopile converts IR radiation into voltage signal proportional to temperature
🔄 Operation Process
Thermopile absorbs IR radiation from the target
Generates a small voltage corresponding to energy absorbed
Internal amplifier converts voltage → linear analog output
Microcontroller reads voltage → converts to temperature
