Story

THIS PROJECT IS BASED ON GSM MODULE AND ULTRASONIC SENSOR

I HAVE USED -Arduino, GSM module, ultrasonic sensor, LEDs

the main idea is :

A GSM-based security system is a system that uses a GSM (Global System for Mobile Communications) modem and an Arduino board to provide security for a specific location. The system can be programmed to send an SMS/CALLS to a designated number in case of an intrusion or trigger an alarm. The system can also be controlled remotely through SMS commands....(USING AT COMMANds)

THE COMPONENTS I HAVE USED :

STEPS :

step1:

connecting the GSM module and try if it works using AT command

testing the network and weaking up the GSM module

I have used this data sheet

STEP2:

try sending calling and receiving sms from to the phone using this data sheet

STEP3:

Connect ultrasound and try it alone and display distance in serial monitor.. Once you have chosen the right distance for you, keep it in the code..

distance

STEP4:

Fasten the components together using the breadboard strip and install the LEDs as additional options (green for normal) (red for danger)..

THIS FOLLOWING PICTURES SHOWS THE FINAL RESULT OF THIS PROJECT

THAT WAS ALL STEPES THAT I HAVE FOLLOWED TO BUILD THIS SIMPLE PROJECT.
