Microcontroller Based Data Acquisition And Supervision

ABSTRACT In this research paper we 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 project. We have covered the hardware and software requirements for designing such a system. The paper covers the basic design of the project along with the block diagram. We have divided the entire design into sub circuits that cover the bridge rectifier relay driver and A to D convertor. We have covered the software simulation of the sub circuits. The results of the simulations have been compared to the expected outcome and so we know that the design is working properly.
