In this project, when a motion sensor (PIR) detects a movement of an intruder, an SMS will be sent to a predefined number which could be you or your security reaction company and if it is not disarmed within 30 seconds, a relay will be triggered to switch ON the siren or any other sound device. When the device is turned on, it needs to be armed by pressing the push button then it will give you one minute to allow you to safely exit your home or sleep without triggering the alarm. After that, the program enters the alarm mode, the program will constantly monitors the input from the PIR. When motion is detected, the device will send an SMS message to a predefined phone number stating: "Alarm!! Intruder Detected in your House!!! Siren will be activated in few seconds.".
In this project, The ambient Temperature is read every Hour then sent to a specified mobile phone number as SMS Text Messages. When the device is turned on, The GSM module is initialized, then the program goes into an endless loop. The Temperature is read, sent to a specified mobile phone number as an SMS Text Message, then the program wait for one hour before reading the next temperature value. The LM35 Precision Temperature sensor is used to read the ambient Temperature, the Telit GM862-QUAD GSM/GPRS module is used to send the SMS Text Messages. The project uses MikroC Pro for PIC Compiler
A GSM modem is a wireless modem that works with a GSM wireless network. GSM stands for Global System for Mobile communications, this architecture is used for mobile communication in most of the countries in the world. A wireless modem acts basically like the traditional dial-up modem, the main difference is that a dial-up modem sends and receives data through a fixed telephone line while a wireless modem sends and receives data through radio waves. Besides the dial-up connection, GSM modem can also be used for sending and receiving SMS which is also one of the key features of GSM modem. In this article we are going to learn how to send an SMS text Message from a PIC Microcontroller using Flowcode for PIC.
