I should, im the manager. I just dont know how all the circuitry works tho. but why be scared of my knowledge, you a scumbag Then

Hi Idio..... Welcome! What do you think? I will help you find what you need if you wanna do this. I promise you, it's not really difficult.

What it seems you are after.....Is a very simple 'silent' alarm system. The control panels are usually in 12vDC, and have normally open, and normally closed circuits, so you can choose how to switch it easily. They will run large current dc Volts, and usually have a 240v double pole relay too.


It is also normal on these boards to have 'double knock' or 'triple knock', before switching something for you. You can also easily wire it so that it requires BOTH sensors to trigger at the same time to work. That means you can have a minimum/nil false alarms, using infra red, both passive and active. The difference is passive detects 'warmth' [actually IR light] in a certain field. Active IR detectors are the 'break a beam' type. There are MANY other types of usable sensors, and they are cheap too at electronic outlets.

These are invisible detectors (OK, less visible), linked to a hidden control and can switch a fan on or off easily, and/or the light if you wish. An upmarket one will phone you and give you a message according to what the sensors say. These are easily within the reach of people who are able to wire a ballast, for example.

They are mostly 12v so quite safe, and cheaper/older ones will have some tiny control switches inside. These are easy to set up. A set up to do what you asked would cost say, £30-35 here, and a bit of fiddly wiring. Quite simple though. 1 Panel, 1 passive IR, 1 Beam, with switchwires back to your cab. Siren or no siren, it's up to you. 1 A telephoning model is quite hard to set up, but should be no more than double the cost. A cordless system is a piece of cake to set up, but more expensive still. [and it would only be the sensors that were cordless].

Alright. Thanks for the advice.

The person who wishes to do this project lives in the States, so hardware stores, Wally World, and Home DePot are the only real options for finding electrical help. The break-a-beam option sounds great, as it could possibly cover stairs leading down to the cellar. If one who knows where the sensors are jumped a step, the growbox can continue its business while receiving care from him/her.

The growbox is hooked up to an outlet, so one main plug can be attached to the sensor trip to turn the whole thing silent and dark. How might one insert the sensor, and what is needed? What materials are needed, and are there any premade models one can easily buy?

Also, how does one count the number of securty breaches?


Thanks for all your input, guys.

I hate being sketched, but it's good to be assured you're the only one looking at your crop.

Hey Idio..

The control retains information about which zone was set off etc. It uses the on/off of the beam sensor to trigger it's output. In this case, to switch OFF your cab[or just fan circuits] , for a period of say 20 minutes. It's that simple. Kat

BaadPuTthyKat, until I find a model for sale around, I probably will not be able to figure out what you're trying to explain. But I figure I need a basic control, a motion sensor or a break-beam, and an off function with timer. Something like that, and maybe you could help me modify it if I can't get it down to that exact.

I've been browsing the local Home Dopeit and I only saw lights with motion sensors. Couldn't very well find a basic motion detector. Will try Radio Shack. If anyone can find one online for cheap (the control, a simple sensor, and an off function for 20 min), I'd appreciate a link. Thanks for the advice.

understanding your desire to be safe, especially in the US, I have to ask isnt there an easier way? I mean you are in a basement, should only have 2 main entrances, a stairway from inside the house and one from outside. Windows are negligible because a piece of plywood secured on the inside over the opening would prevent entry. Paint them flat black so they kinda "blend in".
The 2 doors could have Keypad locks on them. Only the person that knows the combination would be allowed entry, and they are much harder to pick then you standard key lock.
The grow itself could even be located behind a false wall with sound proofing added to kill any extra noise. All the equipment that makes noise or causes vibration could be isolated fairly easy using foam pads or cork pads. Ballast could sit in a sound proofed space as well.

Doesnt sound easier? Well to be honest with the way you are stressing security these measures should be a shoe in. Done right, your security should not be compromised. And the reason I say shoe in is even if all your sensors work the perp still has atleast 5-10 minutes to work. Ever watch "It Takes a Theif" on the discovery channel? Those guys haul tail through a house. If your basement is the entry point and sets off alarms or only shuts down fans, if he sees a locked room or box hes gonna attempt entry. And if by chance its LEO, he could care less about he alarms cause hes there for 1 reason IMO..

I have gotten quite interested in this and have been doing some digging.

An infared garage door sensor could probably be rewired to work to this effect too. Are you good with wiring and electronics?

TBO-Tech has all kinds of home alarms, but most of them are just equipped with a siren or alarm. With a little altering you could probably hook it up to a socket.

I found a motion activated light switch on ebay for under $30 shipped. I'm sure it can be easily found at Wal-Mart, Home Depot, or a local hardware store.


Found this motion sensor kit at Micro Systems Technology.


Good Luck, hope this might help some!

^^ That kind of product is what I've been looking at recently. It will turn on a device, but I wonder if it will be able to turn off a device. Home DopeIt had nothing but external lights. I'm going to browse some electronic shops in the area today.

The reason I'm so bent on this idea is really for two reasons. One, I'm really damned interested and would like a working model for a few reasons, including future uses for other things. Second, the cellar has one stairway down to it, and I'm not the only one who stores things down in that room. Although [my cabinet] honestly looks like another trash heap down there, I can still hear a faint fan humming, which is what I"m after to keep quiet. Of course it can be attributed to the numerous working processes of a normal house, but I'd just like to keep any hint of where the cabinet is to the minimum.
