Gas Sensor and Heat Sensor

During the past few decades, gas sensors are based on surface characteristics or on some of bulk electrolytic properties of ceramics which has been the extensive result of research works. From air to fuel application of these types of sensors ranges to the most. In industrial leakage of toxic gases set for the application of sensor that detects all harmful effects. There are various gases that are involved in gaseous sensor work. On the other hand it is also true that world is getting warmer day by day and this is really affecting our day to day activities. So to measure the temperature, heat or temperature sensor has been invented. It actually quantifies the heat content of the body on a scale. In this particular topic of comparison research we have studied about chemical and heat sensor. In this particular research paper we are also studying about the emerging technology of gas and heat sensor. Gas sensor is mostly used in chemical purposes such like industrial hazards and security purposes. In all section of all activities of mankind it is been used widely in industry.
