I just made a alarm that sends a twitter message to your Phone/Tablet when someone enters a room.

The electronics are simple: just a NodeMCU with a control led and a PIR.

Basic program is just 16 lines of code !!!!

That is right 16 lines of code is enough to detect a movement with a PIR and send a message to twitter !!!!
Well.... the message is send to IFTTT which send a message to twitter. Nevertheless amazing.

Hi - I went there and read the article (thanks) and was interested in this IFTTT that you used, so read your previous blog articles about it. I was able to create a free account ok but failed at the next step on your page where it says "First click on the tab 'My Recipes'" - I cannot find any tab like that and searching for "recipes" does not help!
Any idea what I am doing wrong?

- Sat May 06, 2017 12:03 pm #65654 I just read that blog post. It was very nice.

Only thing I would have done differently is use an interupt on the pin trigger from the pir sensor. To prevent the device from being in a constant loop state.

Other than that I have to commend Luc Volders for making an excellent tutorial.
