One too many times I’ve seen dogs furiously panting away in the car on a hot summer day while their owner carelessly shops in air conditioned bliss. So if you’re of the forgetful, or just not aware of the temperature, do your dog a favor and get one of these. The Hotdog Temperature Monitor wires into your vehicle and when the mercury crosses a threshold the device will roll down the windows accordingly and alert it’s owner by flashing the car’s lights and horn. There’s even an optional pager that can receive notifications up to a mile away, which doubles as an intrusion alarm when paired with an optional sensor.
