Title: Design of NDIR Thermopile-Based digital board
Keywords: AFE; NDIR; thermopile

Abstract: The current paper represents the design of a digital driver board for NDIR sensors, which contains of an lamp driving circuit, analog front-end (AFE) part and analog-To-digital conversion (ADC) part to build up a low-cost, low-noise and high-Accuracy 24-bit data acquisition platform. The NDIR sensor output signal is amplified and filtered and the recorded signal of the ultra-low noise 24-bit \Sigma\Delta ADC is analyzed in the time and frequency domain
