Overview on Temperature Sensors Working and Latest Applications Circuit Diagram Where, T is the temperature in Kelvins. R is the resistance of the thermistor at T (in Ohms). A, B and C are the Steinhart-Hart coefficients.. To solve this equation you need to know the value of the three constants - A, B, and C. These constants will vary depending on the type and model of the thermistor and the temperature range of interest.
Or you can touch the sensor with an ice cube, preferably in a plastic bag so it doesn't get water on your circuit, and see the temperature/voltage drop. (See image below) Connecting to your temperature sensor These sensors have little chips in them and while they're not that delicate, they do need to be handled properly. A Basic Thermistor Circuit. Let's build a basic thermistor circuit to see how it works, so you can apply it to other projects later. Since the thermistor is a variable resistor, we'll need to measure the resistance before we can calculate the temperature. However, the Arduino can't measure resistance directly, it can only measure voltage.

In this Video We Make a Temperature Sensor Circuit Using Thermistor. the Temperature Sensor is Used in Many Electronic Applications Like Temperature compensa
Caution must be maintained, not to exceed the temperature over the transistor above 120 degree Celsius, other wise the device may get burnt and damaged permanently. The proposed simple temperature indicator circuit can be further modified for making it switch an external appliance ON or OFF in response to the sensed temperature levels.
