Temperature Detector

Temperature sensor is an electronic device which is used to detect temperature. In this project I have used TMP36 temperature sensor. It is a low voltage precision centigrade temperature sensor. Unlike thermistor, it uses property of diodes, as diode changes the temperature, the voltage changes with the same rate. 

Connection

1) Arduino 5V connected to Sensor pin 1

2) Arduino Ground pin connected to Sensor pin 3

3) Arduino analog pin 0 is connected to sensor pin 2.

So this was overall connection of temperature sensor.

4. Petrochemical handling

Disadvantages of Temperature sensor

1. Non-linearity
2. Self Heating
3. Expensive
4. Low Voltage
