# Smart home design and ESP12e Nodes

> Smart home design and ESP12e Nodes

Original author: george (source: https://community.mydevices.com/t/smart-home-design-and-esp12e-nodes/2010)

## Components

- **Arduino uno r3** x 1
- **ethernet shield** x 1
- Software: **Arduino IDE** ([docs](https://www.arduino.cc/en/software))

## Documents and links

- [ESP12E Dimmer code](https://community.mydevices.com/t/smart-home-design-and-esp12e-nodes/2010/3) (code)

## About This Project

A Smart_home system with ESP 12E sensor and activator nodes. Which i can monitor inside outside temps, unlock entrance door, open-close central heating and enable-disable corridor pir lights. If anybody intrested i can share the codes of arduino and ESP12e nodes

## What’s Connected

*For central unit* Arduino uno r3 PC817 optocoupler 4 channel relay board Ds18b20 sensor 1K resistor 4.7K resistor 9v power supply jumper wires *For outside temp node* Nodemcu v0.9 board Ds18b20 sensor 4.7k resistor 5v usb phone charger micro usb cable jumper cables *For dimmable led controller* ESP 12E 12v power supply LM317T 220R 360R BC327 LED strip

## Triggers & Alerts

I was using 2 Pir sersors externally which triggers 12v to led strip on corridor, i connected one optocoupler to this 12v output and triggers to arduino input. If any motion detected, arduino input trigers and cayanne sends sms

## Scheduling

none used
