    Hello

    First post on the forum

    I.m looking for a wireless solution using the least amount of component to sens the opening of a door.

    My actual system is wired to a buzzer using a magnet and a reed switch. I'm looking for a way to get the reed switch level ( close, open) in a remote way.

    Distance: only 1 or 2 meter max

    The solution will need to be tiny because ideally the transmitter will need to use about the same place as the door switch

    Any idea if a of a one chip solution do exist?

    Excuse my English, more fluent in French :)
