Building a Remote-Controlled Alarm/Siren System: Components & Connections

[Klutch1]

I have no clue on the first thing to start with. I want to make a remote that signals to a siren/alarm.

1) what kind of electronics/components would I need for a sensor.
2) how can I get it to connect to an alarm/siren sound?
3) where can I purchase the components to make this?

depends on what you want to sense ?? you haven't told us
do you want to sense a change in light level ? maybe a motion?
a fluid level?

2) how can I get it to connect to an alarm/siren sound?

the sensor, once determined, could be used to trigger a 433MHz radio Transmitter and
the alarm unit connected to and triggered by the receiver

3) where can I purchase the components to make this?

depends on what country you are in ??
for the USA and some countries digikey, mouser and even eBay will source most parts

cheers
