DIY Smart Home Security Arduino+SIM800L+Infrared

Gsm based Home Automation are used to control Home devices Like TV , Lights , AC etc.

just take an example , if there are sunny day and you want to Turn on your AC Before you Even Walk In the Door.

So for this you have to send a SMS then AC will be turn on.

It is simple way to save electricity and make our home smart.
