Darlington npn transistor 1 50 or a relay 2 5 i like the darlington as it is cheaper and solid state and easier to wire up but depending on your specific garage door a relay may be a better solution genie garage doors have a lower contact voltage and a darlington can not bring it close enough to ground to.
Wemo maker garage door sensor.
Garage door was closed or something similar how often.
If you just want to be able to open or close your garage door then the wemo maker will suffice.
The wemo alerts will appear on the lock screen.
There was already a 120v wall outlet and all the items needed to keep the wemo maker in a climate controlled environment.
Wemo maker 79 99.
I did coonect it to a sensor so it will show that the sensor has been triggered or not in the wemo app.
The magnetic sensor and speaker wire are optional.
Speaker wire 21 42.
Arduino uno rev3 board or likely any arduino will do 25.
I used the wemo maker to operate my garage door opener.
I ran both the magnetic door sensor wiring added the 22 2 wiring for length as well as a cat5 cable i had connected to the garage door opener ports red white on the garage door to my master closet.
A while back a mate asked me to connect his garage door to his phone.
Magnetic sensor 5 90.
It works excellent for that and the setup is very straight forward.
The switch is actually triggered when the door is closed.
All day daily keep in mind this may be somewhat counter intuitive for those unfamiliar to normally closed switches.
Wemo maker sensor triggered notify me.
