People in different social environments are growing each with the opposite sex, burglary led to frequent, so we need to build an anti-theft system, fire alarm system. Although the market has a variety of intelligent room security alarm systems, but these systems due to the frequent occurrence of false positives and false negatives, etc., but the high cost, the average user is not universal use. So we very necessary to develop a cheap, practical, simple structure, high safety factor bedroom alarm system to meet current security needs of our peoples lives. The design is done by the STC89C51 core device designed as a bedroom alarm system, with sensors as environment variables passed to the STC89C51 for processing recognition judgment, to achieve the alarm function. After the transfer of this design is the use of STC89C51 as the core components of the system, coupled with human infrared sensor, smoke sensor identification to identify environmental variables, converted into a digital signa
