temperature controlled remote start

I am installing a remote starter on my 2002 Ford Explorer. I transport canines inside my vehicle. I want to be able to add a high temperature switch that would send one negative pulse to my remote start to activate it if the ambient temperature in the rear of my Explorer reached an adjustable temperature (90 in summer, 40 in winter). It must only sent one pulse. If multiple pulses are sent until the car cools, that would lead to will turn the system cycling on/off and overheating the dog. An bonus feature would be if the unit heat 95 and with no change, it would drop windows, activate fan, and sound horn. I am not new to 12 volt electronics but wanted some different viewpoints on the best way to accomplish this task. My priority is the activation of the remote start to prevent overheating.

You could set older Clifford products to activate remote start on a lower temperature via the Wiz.  Not sure how you'd do that now, I think Mr. Pearson and Mr. Idiot have to come in here. Try PMing those two and Dualsport.

Why don't you just move the canines into a more conditioned environment, when your away?Ideal - cmon dude, add to topics in a useful manner, not stuff that is obvious.

Story - Phzzzt! Hey, what happened?! ... Isn't it obvious?

Moral - Never dismiss the obvious.

I located an out-of-production model of the DEI 556T Valet Digital Remote Start Controller and Timer on eBay for $29.99. I figured the solution would be more reliable, cheaper then putting my own together. The manuals on this website were also helpful in determining if this is the product I needed. https://www.the12volt.com/installbay/file.asp?ID=756 https://www.the12volt.com/installbay/file.asp?ID=755 Thanks for everyone's help. Also, if someone had more money to spare, they could buy a more expensive solution like these: http://www.rayallen.com/product/f_series_k-9_deployment_and_heat_alert_systems/K9-Transport http://www.criminalisticsinc.com/products/hotdog/hotdogplus.htm http://www.radiotronics.com/k9ha_pro/k9_heat_alarm_pro.html
