Smart home design and ESP12e Nodes

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
