4 in 1 LED Light

Image
First  project idea from  Project Blank  to see the light of consideration. Proposed by the PFT department, specifically Mr. Real Barua. I contributed with the feature of Main & dream light in a single bulb and the PFT department suggested the gas ditection feature. The last existing & well adapted feature is giving a backup support. The system  can trigger motors to open the ventilators, breakers in the case of a gas leakage. Also by adding some  GSM  capabilities to it we can send warning messages to the user.  Though the group is kind of discontinuing or holding this project, I'd love to build it. Especially cause I have the wiring diagram ready.
