In this study, the temperature control device was designed for the study in order to detect theoutput in frequency of temperature, and the study confirmed accurate temperature values treatedsystemically by using expanded A/D converting Technology. The control technology of functional sensorincluded the output error Detection. For the future study, it is necessary to implement a control device bybuilding multiple circuits integrally with different types of sensors such as a automatically and intelligentnotification function sensors.
