That combines prevention, guard against burglary, prevent gas leakage, fire alarm functions such as multi-function alarm system. Infrared pyroelectric infrared sensor alarm (fe mud filter) with BISS0001 chip production of infrared sensor module, detection for human existence. If detected by the human body, data output high level, or for the low level. Gas leak when MQ - 5 by monitoring the concentration of the gas sensor for gas leak prevention. Alarm module includes local alarm with remote alarm. Local police using LED alarm and horn. Remote alarm used the most widely coverage, signal stability is good, do not need to users of GSM mobile communication network maintenance, using text messaging.
