High Temp Shutdowns?

[FlowerFarmer]

Hello,

I'm looking for something to kick off my lights in the event that I have an AC failure.

I'm using 240v light controllers/relays with 120v trigger cables so a stand alone high temp shutdown is what I need. Just something to go between my trigger cable and my timer/outlet with a remote temperature probe to dangle in my canopy.

I know CAP used to make something like this. HLC or whatever, but I've been unable to find anything similar now a days.


Does anyone have any suggestions of what is available at the moment?

150 bucks down here in oz, but I have seen similar in usa. I don't have this unit, but two other products , they do what there supposed to do.

monster gardens have them= 105 dollars. probe etc.

Arduino microcontroller + temperature sensor + relays = piece of cake programming and wiring, cost about $40. Should give you the best versatility, if you're into electronics and programming (but not deep into them, basic C or Java should be enough to grasp the language instantly).

Temp controllers are widely used by advanced aquarists-

Industrial grade from a very reliable supplier. The power ratings are for resistive loads, but they'll work fine in a 120v control circuit. If you want the system to turn off & stay off you'll need to wire a lockout relay as well.

And you can also use the Arduino as a timer to turn the equipment on and off at specified times. And then add an intake fan that turns on a few degrees above the shutoff temperature. I have 13 temperature sensors, 8 humidity sensors, 3 hid lights, 3 fans, 4 water pumps, and 11 leds connected to an arduino. Mine goes a step further and logs the data too. All cheaper than a single thermal shutdown.

You can even go a bit further with arduino and receive emails or texts when anything unusual happens. But it does need at least an intermediate electronics knowledge and lots of time to set it up, code it, test it, ect..
I'm working on a light dimmer for leds that will control their brightness based on temperature.

220V All-purpose Temperature Controller STC-1000 of e-bay
I got one haven't stopped using it in 3 years great tool!
great value as used by home brwers and light users too ...lol

Of course you need some knowledge in electronics to implement such functions in an arduino, but for what OP requires three fingers and basic logic are enough IMO.The time consumption grows exponentially with improvements you're trying to make to the arduino setup =)

 

[FlowerFarmer]

Agreed. Pretty neat stuff though.


The local store around here stopped carrying sunlight supply stuff so perhaps that is why I didn't see anything in their catalog. The one with delay from titan looks exactly like the HLC I was familiar with in the past.


Thanks for the replies everyone.

someone that is not electronics inclined and has not played with electronics in the past will need lots of help with even basic arduino functions, IMO.
on the other hand there are lots of books and guides out there, so yes, with enaugh time and energy spend on this, it can be done by anyone.
