| Summary: | Over the last decade, advances in digital electronics have made computer smaller,
cheaper and faster. Throughout this revolution as well, mobile computing environment
such as PDA has been created and undoubtedly other advances in technology like smart
home also play an important role towards better life in the future. This project is about
how we can control the fan based on temperature sensor regardless of traditional
thermostat. It is also part of smart home application where the fan will gradually increase
the speed if the temperature in the environment is increasing. Besides that, the component
that made up the temperature sensor is known as thermistor. A sensor is a type of
transducer. In a broader sense, a transducer is sometimes defined as any device that
converts energy from one form to another.There are two types of thermistor depend on
the sign of k. Firstly is positive temperature coefficient (PTC). PTC thermistor works by
increasing the resistance with increasing temperature. Secondly is negative temperature
coefficient (NTC). NTC thermistor works by decreasing the resistance with increasing
temperature. This project will focus on NTC type of thermistor. Experiment can be
followed to evaluate whether this circuit can save energy through the use of temperature
sensor and thus promote efficiency. Finally, after some experiments have done, the result
of the experimentation and finding can be concluded. |
