Full Fledge Home Automation Using NodeMCU (Blynk)

This system is to make entire building Automated starting from evening laps all the way to Terrace water management system. With only one Access Point (wifi). This will make you feel like you have built Tony stark lab.

There is a Mains MCB which triggers the power supply of building. This one MCB controls everything. We have to make this also Controlled via Phone so we will make first Board which is quiet simple and this board will always be on this will turn off only when MCB is turned off.

Terrace setup with solar panel, water level and flow. This is a place where getting Internet access is tricky so we are going to add Powerline adaptor to solve the issue of internet access. This adaptor is reliable and useful and it will extend internet till you have 3 phone power wire routing in the building.

• the solar panel is a small 5v panel which is given to input of the controller. Based on the brightness of the sun the voltage is varied and hence forth the controller gets to know what is status of the time and based on any weather it will work accurately.
• Flow sensor is to make amount of water consumption and water level sensor shows the level.

Main channel we can add as Many outputs to this channel
