Remote temperature monitoring with Arduino and GSM
After the hot water system and heat failed in his holiday house, Matt Tilchen needed a way to check that on the new hot water system regularly without having to physically visit the house. Although sending sensor data via the Internet sounded promising, that would incur an unwanted expense of a connection just for some data. Instead he used an Arduino combined with a DS18B20 temperature sensor and a GSM Arduino shield. On a regular basis the Arduino would send the temperature data via SMS to Matt's phone - or if a sudden change in temperature occurs it would SMS immediately. And if it didn't send a message after a period of time - he also knew there would be a problem. Anything to avoid a repeat of the damage shown below:
