Fire alarm system performs an foremost function in keeping and monitoring the trustworthy of all type environments and situations. However the usability of many existing hearth alarm system is good recognized however could be produce with excessive cost. Therefore, it is no longer low-priced for the low sales users. The main function of this undertaking is to make a fireplace control system with low rate. The challenge has three fundamental methods, 1) the detection system, 2) the monitoring approach and 3) the appliance system. The detection system operates as the fire detector. This detection method has add-ons like flame detector, smoke detector, light detector, heat detector and many others. This paper discusses the design and implementation of a fire alarm method making use of the microcontroller which operates the whole method.
