In this paper, the authors have designed a system that acts as a temperature sensor and also a warning system the system also has the facilitation of shutting down the machinery whose temperature is to be monitored. The main function of the system is to constantly monitor the temperature of a machine, compare it to a predefined limit and shut down the machine if the temperature exceeds or falls below that limit. The system is highly useful for systems with high dependence on particular temperatures. The paper includes the requirement of such a system along with the idea behind development of the paper.
