Exploring our temperature sensor (TMP37)

“

- [Narrator] There are many types of temperature sensors available. Each is used for different applications according to the specific requirement of your project. Maybe you want a temperature sensor that measures a wide range of values, or one that needs to be very sensitive to small temperature changes. Most of the temperature sensors used with an Arduino board have the same pin layout with three pins for each sensor. These temperature sensors are analog and produce a voltage that is linearly proportional to the temperature in degrees celsius. So now we need to know the voltage range that the sensor produces and take into consideration the voltage reference that the Arduino is producing. For example, the Arduino Uno uses a five volt reference voltage. So the maximum sensor voltage is five volts. So our temperature sensor is TMP37. It has a low voltage range using a reference voltage between 2.7 and 5.5 volts. This sensor matches the voltage reference of the Arduino Uno, which is five…
