    I have an idea about using an old phone to tell me the temperature at a remote location. I need to know when a greenhouse or any remote location approaches freezing by sending an alarm to my computer or another Android phone. I thought about something similar to remote GPS locating but getting the temperature data instead of the GPS data. I could just leave my old Android phone in the Greenhouse. I know absolutely nothing about App development, I started to look at the SDK but first I needed to know Java, BASIC is as far as I ever got on a BBC.

    How would you get the other phone to detect the temperature? That's the main issue I can see. Getting the phone to broadcast a signal of some sort (email, SMS, phone call, whatever) when the temperature reached a certain point wouldn't be terribly difficult. Getting the phone to pick up the ambient temperature of the room would be the harder part. I don't think the phone is designed to do that or has that kind of sensor in it.

    Is the temperature sensor on these phones just measuring the CPU temp or perhaps the battery? Like I said, I know very little about this stuff, only got my first Android phone 2 weeks ago.

    It can monitor CPU temp and it can monitor battery temp (at least on some phones). I don't know of any that monitor ambient temp. I know you can purchase sensors that monitor ambient temp, plug into a computer and can generate email and/or text alerts if the temperature reaches a certain point. I would look at something like that as a better solution.

    It might be possible to wire a thermostat to a 3.5mm plug, set the thermostat so that it closes (or opens) the circuit at the "alert" temperature to trick the phone into thinking that a headset has just been plugged in, and use something like Tasker to send an SMS on "headset plugged".

    I don't know anything about how the phone detects the headset though, so this may not even be possible.

    If that's not possible, you could wire the thermostat into a charger so that power to the phone is cut when the alert temperature is reached, and have Tasker react to that. Of course, it would also trip during a power failure.

    Depending on your budget, there are solutions for exactly what you are looking for without having to reinvent the wheel...but they are expensive.

    I found one of the services but it is $500+ and requires monthly subscription. I'm looking for the same idea. I take my dogs with me everywhere and during the summer I leave my a/c on for them in the car if I need to run in to the store or get a quick bite to eat. I'm so afraid that my car will turn off or a/c quits working...has anyone figured out an android app to get a temperature reading in a car or I guess anywhere? I purchased a wireless thermometer, but as soon as you enter a building, you lose signal. With so many apps and dog lovers like myself, there has to be something out there that is reasonable. Can anyone help?
