Hy guys
I have a automatically sectional door for my car garage.
I need to pay and install a additional platine to use a relay or some other cable button.
So I don't want a new remote button.
I want to install a sensor, which detect, when the door is closed. That's all
Which sensor can I use???
I don't want to know the position. Only to know if it is closed
Thank you
A microswitch operated when the door is closed or a Hall effect sensor near the door and a magnet on the door would be simple solutions
Optical (beam break) sensors are also used with such doors. It is important that if there is an obstruction, the door does not attempt to close.
