288 The Smoke Alarm System Based on S3C2410A

The design is based on 32-bit ARM920T processor S3C2410X as the main chip, it adopts embedded LINUX system as the operating system, and it designs a security control circuit -- smoke alarm system. Which uses MQ-2 combustible gas sensor-type semiconductor Smoke Sensors to detect smoke, it has a high sensitivity, fast response, anti-interference ability etc., and the price is low, long service life. S3C2410X selects chip, which integrates A / D conversion, hardware multiplier. The hardware resources such as pulse width modulator with a high speed is low power consumption, powerful anti-jamming, etc., which is the price of similar products with higher technology.
