Homework Help: Project: get a sms when my electricity falls out

  1. Feb 22, 2012 #1
    1. The problem statement, all variables and given/known data
    I am in my first year electronics/ICT but have already successfully completed several courses about electronics, microcontrollers, programming, fysics...
    I have to make a project in my second semester and im really interested in domotica, so thats why i want to do something about that.
    My idea was to give a little domotica touch to a holiday house of a friend:
    1. get a sms/or check on a website when the electricity falls out
    2. get a sms when the temperature is to low (below 5 degrees) or check on a website the temperature of the house

    My ideas of the solution:

    I was thinking to put a microcontroller with temperature sensor in his living room, when the electricity falls out, a battery has to take over the microcontroller and has to send an sms.
    The microcontroller is connected to a website where you can check the state of the temperaturesensor.

    2. Relevant equations
    I know he has a Theben wireless thermostat, is there a way i can connect the microcontroller directly to the thermostat so he can control the temperature from his own house?
    Or can i connect the microcontroller to the boiler to archieve this? so the microcontroller takes over the thermostat function?
    If the electricity is on i can connect the microcontroller to the internet so het can send the information for the website? any ideas how to do this?
    If the electricy falls out i have no internet anymore so i was thinking about sending an sms with an gsm module in the microcontroller. any ideas how to do this?

    3. The attempt at a solution
