Design of the intelligent fireproof and theft-proof alarm system for home

Abstract：According to present situation of fireproof, theft-proof alarm system for home and other remaining questions, the intelligent fireproof and theft-proof alarm system for home based on public telephone net is introduced.In the system, photoelectric smoke sensor, temperature sensor, pyroelectric infrared sensor, microwave sensor and CO sensor are adopted as detection elements, and the MUC is used as control core.The intelligent alarm function is completed by using DTMF signal chip and integrated speech sounds chip.The multi-sensors make the least error-alarm and enhance the reliability of system.
