### SIMULATION OF TEMPERATURE SENSOR USING LABVIEW

1. 1. PREPARED BY POOJA SHUKLA(190912066) PRIYANKA RANJAN(190912072) INTERNAL GUIDE Mr. Y. BHASKAR RAO Assistant professor ECE DEPTARTMENT TEAM NO: 5, ECE
2. 2.  The trend of miniaturization in electronics has led to greater heat densities within computer chips, demanding high performance heat sinks at smaller and smaller scales.  The equation used within VI program is used to calculate the resistance of thermistor with respect to the excitation voltage and the temperature variation can be measured. TEAM NO: 5, ECE
3. 3.  To Design the Temperature sensor circuit using Labview simulator.  Analyzing the variation of temperature at different intervals of time periods on the basis of the application used. TEAM NO: 5, ECE
4. 4. TEAM NO: 5, ECE  LabVIEW programs are called as virtual instruments (VIs)  Because their appearance and operation imitate actual instruments  However, they are analogous to main programs, functions and subroutines from popular language like C, Fortran, Pascal, …
5. 5. TEAM NO: 5, ECE  Front Panel • Controls = Inputs • Indicators = Outputs  Block Diagram • Accompanying “program” for front panel • Components “wired” together
6. 6.  In many systems, temperature control is fundamental. There are a number of passive and active temperature sensors that can be used to measure system temperature, including: 1. thermocouple 2. resistive temperature detector 3. thermistor 4. silicon temperature sensors TEAM NO: 5, ECE
7. 7. • These sensors provide temperature feedback to the system controller to make decisions such as, over-temperature shutdown, turn-on/off cooling fan, temperature compensation or general purpose temperature monitor. TEAM NO: 5, ECE
8. 8. • Signals are input to a sensor, conditioned, converted into bits that a computer can read, and analyzed to extract meaningful information.
9. 9. TEAM NO: 5, ECE  We can measure temperature more accurately than using thermistor.  The sensor circuitry is sealed and not subject to oxidation.  The LM35 generates higher output voltage than thermocouple and may not require the output voltage to be amplified.
10. 10. TEAM NO: 5, ECE  It has an output voltage that is proportional to the Celsius temperature  The scale factor is .01V/oC  They does not require any external calibration or trimming  It maintains an accuracy  It draws only 60 micro amps from its supply and possesses a low self-heating capability
