This isn’t about connecting a temperature sensor in your Arduino. This build is about using the temperature sensor in your clock.

Thermistors, which range in price from 10 cents to approximately$25, find use in applications from automotive monitoringand exhaust-emissions control to ice detection, skinsensors, blood and urine ...

I used an LCD shield to display the current temperature and speed of the fan, but you can use the circuit without the LCD display. You also need to select the transistor by the type of fan that you ...

Sens-A-Coils feature a sensor housed in a small bulb attached to copper clips. The sensors use fast-response thermistors in a plastic over-molded copper-clip that snaps onto 3/8-in. return bends ...

Temperature-measurement sensors are typically thermocouples, RTDs, or thermistors. If the parameter being measured is very sensitive to temperature, placement of the temperature sensor is important.

And they require no adjustment between control circuit and sensor. Available in all resistance-temperature curve materials, the NTC thermistors have resistance values at 25ºC from 1 to 47 K?.
