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.

The device is simple — it uses an Arduino Nano hooked up to a thermistor to measure the temperature of fluid in a pot. The microcontroller displays the current temperature and the target ...

The T400 is compatible with a wide variety of K-type thermocouple sensor types from stainless steel probes to rolling surface-contact sensors. The Arduino compatible Pax Instruments T400 ...
