This has been a major question with RVers traveling with their pets. For some it was a reason not to go to a museum or sight-see some special area because there was no way to know. We have all read the horror stories of an RVer coming home to find their pet in a fight for its life or dead because of overheating in a hot RV. Or worse yet did the power at the RV park go off and come back on and reset everything, so that the air conditioning or heating system is not set to the right temperature?
With modern technology it should be simple and affordable to know if your pet is safe, while you are out enjoying the sights near where you are camping. Lets look at some things that may work for you.
1. You will need an Android Smartphone that you will leave in the RV full time. I would suggest a low cost pay as you go Verizon phone. The reason for Verizon is that, a Verizon Phone will work in more places than any of the other Wireless Phone Companies. And for an RVer who is moving all the time you never know where you will be.
- The phone needs to have bluetooth
- Temperature Monitoring Feature (SamSung Galaxy 3 for example)
- The phone must be rechargeable
- You need to have both the AC and DC charger for the phone

You will need to locate the phone where you get the best signal from Verizon and that is also near an AC power outlet. You will also need to download from the Google Play Store an Application called
“Temperature Surveillance” located here Temp Surveillance . The way this system works is the phone monitors your RV with your Android Smartphone. The day to day phone you normally carry with you will get an text message (SMS) if the RV gets too hot, too cold or if a power failure occurs. The text message you will receive will contain information about the RVs temperature and if there is a power failure or not in the RV. All you have to do is tell the App the temperature limits high, low, and the telephone number where you want to receive the text alarms. Then just leave the RV Android phone plugged into the AC in the space you want to monitor and you are done.
