Title : Make some changes on the project
component.
Objective
: 1) To change the LM35DZ to thermistor.
Procedure : 1) The LM35DZ have to be change to thermistor.
Results : 1) The thermistor output is non linear
which is suitable for this project.
Thermistor resistance vs temperature
2)
Thermistor or
thermal resistor is thermal sensitive resistor. It means its resistance changes
with temperature. This change in resistance character divides the thermistor
into two types, depending in the way it responds to the temperature.
3) Positive Temperature Coefficient thermistor. (PTC)
·
thermistors exhibit an increase in electrical resistance when subjected
to an increase in body temperature
4) Negative Temperature Coefficient thermistor. (NTC)
·
thermistors exhibit a decrease in electrical resistance when subjected
to an increase in body temperature
Conclusion: The thermistor
had been used to measure temperature for Smart Chicken Coop because it is inexpensive, rugged, reliable and respond quickly. The thermistor that will be
use is NTC 10k.
