SIREN 100dB Circuit

Published:2013/3/5 20:46:00 Author:Ecco | Keyword: SIREN 100dB | From:SeekIC

This is a very loud siren and if two or more piezo's are located in a room, the burglar does not know where the sound is coming from. A robber will not stay anywhere with an ear-piercing sound as he cannot hear if someone is approaching. It's the best deterrent you can get. The F contact on the piezo is feedback and is not needed in this circuit.
