I just finished my second NodeMCU project, which is a companion for my ESP8266 remote camera trigger.
It uses a PIR sensor to detect movement and a ESP82266 (client) to send trigger command to another ESP (server) coupled with the camera.
Code is available at:
Feedback is welcome.
FYI, I know about nothing concerning electronic, just trying to learn and reproduce what others have shared, and giving back when possible (oh, and english is not my natural language, so feel free to point language issues too ).
