Temperature Sensor Module

We are interfacing temperature sensor module to measure the temperature of the surrounding. The sensor used here is LM35. It can be used to measure temperature with accuracy of 0.5 degree centigrade. The resolution of AVRs ADC is 10bit and for reference voltage we are using 5V so the resolution in terms of voltage is

5/1024 = 5mV approx

The temperature measured is displayed on Seven Segment Display

Note: 

• Take care whether your Seven Segment Display is Common Anode or Common Cathode and so accordingly make the connections.
• Check, if you are using NPN or PNP transistor
• Don't forget to provide a common ground wherever ground is required

The above were some of the things which were neglected by us, that posed temporary challenge for our sensor to run.
