I am looking at getting a DIY alram sensors and wireless receiver. I am looking to connect the wireless receiver to an arduino then have it act as a keyboard emulator and send diffrent key patters based on what signals the wireless receiver is getting from the sensors. I know it can act as a keyboard emulator. Will it be possible to connect the wireless receiver to it and get it to decode the signals?
Im having trouble understanding what exactly you are describing. It sounds like you want two arduinos to communicate wirelessly, one relaying sensor info to the other. Then the receiving arduino sends that info to a computer via keyboard inputs?
A cheap and reliable method of wireless communication is a 2.4 GHz nRF24l01 transceiver. They are around $2~3 on ebay and work well up to 10~20 meters depending on walls and such.
As far as keyboard emulation, this must be done with the Leonardo or the SMD verison of the UNO. The DIP version is not capable without some hardware modifications. I dont really know what those are, here is the link USB Keyboard Support with the Arduino Uno - Make:
Hope this helps, good luck.
Not sure why I would need more than one. Can't I just connect one to this?

I think misundertood, are the sensors GE sensors designed for that receiver and not coming from arduino sensors? To my knowledge, there is no library for communicating between an arduino and that receiver. Due to the fact that it is designed for security purposes, its hackibility its dubious at best.
It dosen't have to be that specific receiver. But Will an arduino work with any security system senors?
I am looking to have the receiver wired to an arduino instead of the proprietary alarm system hardware then have it send a sequence of key presses to match the signals it is receiving.For example senor 1 is broken, the receiver sends its signal over the wire, the arduino would receive that signal and may send a sequence "1" for example to designate that sensor 1 was triggered and my computer would handle the rest. Actuall I would look to have my computer send me mms messages to my phone with camera stills from the area that was tripped, but I can handle that. Its the arduino part I would need help with and ultimately to see if it would even be possible.
I know I have heard of other people using arduino in a DIY alarm system, did they have to make their own sensors or can I get some affordable premade ones to save me the work?
The answer is yes and no.
If you buy commercial premade alarm sensors, then you will have to do the work to figure out how to decode
the data from them.
Its possible, but a lot of work.
If you use your own sensors, then you get to define what data the sensors will send so its a lot easier to decode them.
