This isn’t about connecting a temperature sensor in your Arduino. ... 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.

Once hooked up to your microcontroller, be it a Raspberry Pi or any other compatible device in this case an Arduino microcontroller, it delivers 64 distinct infrared temperature data points using I2C.

A thermistor can be used to compensate for temperature variation in other components of an electronic circuit. Here is an Arduino experiment with a famed linear active thermistor chip MCP9700A from ...
