Design of cost-effective and efficient temperature sensor circuit for total preventive maintenance application

Modern computers have found an array of applications in industries because they are portable and user-orientated. With their huge expense and the ability to give near 100 percent efficiency, utmost care has to be taken while using them in scathing applications. In such cases, factors like temperature, mechanical stress and environmental pollutants can critically affect the performance of these computing systems and may eventually lead to system breakdowns. This may severely compromise with production efficiency as well as safety of people in and around the plant. This work tries to address the problem concerned with the temperature control of the computing system. In the proposed system, an effective and a low-cost temperature sensor circuit has been designed and implemented to monitor the panel temperature in case the panel air conditioner undergoes failure. If the temperature of the panel rises above a predefined threshold, an alarm will be generated which will be displayed on the computer screens of the respective authorities via Ethernet connection.
