Re: Home security

If you know to program microcontrollers with a few tasters on doors and some DC pieso siren (rele which is activated by mcu, switch power of siren) will work like some kind of alarm.
About IR sensor for moving it is isn't expensiv so I think it is better to buy one then to make it yourself. Usualy IR sensors have some rele output which can be connected to mcu so this can be better alarm.
