Automatic fire alarm system based on MCUAbstract：The paper introduced an automatic warehouse fire a1arm system based on MCU. The system was mainly made up of ATmega16, temperature sensors, smoke sensors, and EX-1 auto dialed alarm module. In the system, temperature signals were transformed to serial data, and smoke signals were transformed to voltage signals. All the data were processed by MCU. When the surveillance system checked fire in warehouse, alarm signal was turn on, meanwhile the messages were transmitted to managers through EX-1. Application of the system was convenient to deal with fire in-time, efficiently by warehouse manager.Keywords: fire alarm transducer;smoke sensor system;ATmega16;temperaturetransducer;smoke sensorI.INTRODUCTIONAutomatic fire alarm control system has experienced a process from the simple to the complex and intelligence system increasingly in China. The characteristic is automatic fire detection and alarm technology has a great progress along with computing and detection technology development. At present, automatic fire alarm control system was used in bulk storage plant, shopping malls, high-level office buildings, hotels and other places. They were used in a number of collections focused on one area of intelligent alarm control method with higher levels of bus-type alarm control system, and in some residential areas and commercial buildings were installed by a single automatic fire alarm detection device. These alarm detection devices fail to report sometimes, or misinformation. Its reliability is not high because of using single sensor. Therefore, it is needed to develop a simple structure, low cost, high reliability, fast responding, automatic fire detection system.?II.GENERAL PROJECT OF THE SYSTEMThe hardware block diagram shown in Figure 1, hardware by temperature sensors, smoke sensors, signal processing module, MCU modules and automatic alarm module. Non electrical quantity that is through the sensing element sensors (smok
