【實用工具app】Temperature Surveillance|最夯免費app-gigacircle

Monitor your house, cottage or storage space with your old Android phone. You will get an SMS if it gets too hot, too cold or if a power failure occurs. The SMS contains information about the temperature and if there is a power failure or not.

Just configure the temperature limits and the telephone number where you want to receive the alarms. Then just leave the phone in the charger in the space you want to monitor and you are done.
