This musical light alarm circuit is very simple, uses only 7 components, a LDR and a 3.6 V battery or 3 x 1.2 volts rechargeable batteries. The well-known UM66 is used as the sound generator and will give a pleasent wake up alarm.

As you probably know the LDR is a light dependent resistor. Normally the resistance of an LDR is very high, sometimes as high as 1M , but when they are illuminated with light resistance drops dramatically. In the circuit adjust the 220K preset to the desired sensitivity, meaning adjusting the threshold point wher ....etc

advantages of multi tone siren

A siren is a loud noise making device. Civil defense sirens are mounted in fixed locations and used to warn of natural disasters or attacks. Sirens are used on emergency service vehicles such as ambulances, police cars and fire trucks. There are two general types: pneumatic and electronic.

Many fire sirens (used for calling the volunteer fire fighters) serve double duty as tornado or civil defense sirens, alerting an entire community of impending danger. Most fire sirens are either mounted on the roof of a fire ....etc

In the past, hardwired alarm systems are the only choice for customers who need security equipment to protect premises. Today, with rapid technology evolve, many users shift from hardwired alarm to wireless alarm. It seems home security industry is moving from hardwired to wireless, but as one of mature and stable alarm equipment, some users still favor the hard wired alarm system. In this article, we will show you some basic information about advantages and disadvantages of hardwired alarm systems.
