In our case Arduino is the master and 3 x TC74 sensors are the ... you might notice is that the data is already printed in degrees because this is a digital temperature sensor so we won’t have to do ...

Nice method and analysis. The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.

According to Microchip Technology Inc.’s datasheet, MCP9808 digital temperature sensor chip converts temperatures between -20°C and +100°C to a digital word with ±0.25°C/±0.5°C (typical/maximum) ...

The sensor can be pointed at an object, and the Arduino can sense the brightness of that one point. In order to compile an actual image, [Jordan] needs to obtain readings of multiple points.

No competing digital temperature sensor on the market today can achieve accuracy better than ±0.10°C. The AS6221 is housed in a WLCSP package with a footprint of just 1.5mm x 1mm, ...
