Low cost thermal sensor array for wide area monitoring

Thermal sensors have come into light with the rise of the COVID-19 global pandemic as one of the tools used for screening. There are multiple sensors available on the market ranging from low cost to very high cost. This paper presents how smaller and cheaper sensors can be combined in a larger array of sensors that give better coverage and can be used for shape detection and object tracking. The sensors used are AMG8833 FeatherWing and the platform is Raspberry Pi.
