Introduction: DIY Motion Detection SMS Alarm System

About: Awesome Electronics Tutorials, Projects and How To´s

In this project I will combine a cheap PIR motion sensor with a TC35 GSM module to build an alarm system which sends you an "INTRUDER ALERT" SMS whenever somebody tries to steal your stuff. Let's get started!

Step 1: Watch the Video !

This video gives you all basic information you need to get this build right. But I will give you some additional advice in the next steps.
