Smart home design and ESP12e Nodes

A Smart_home system with ESP 12E sensor and activator nodes. Which i can monitör 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

About This Project

A Smart_home system with ESP 12E sensor and activator nodes. Which i can monitör 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
