Home Automation and Security System Using GSM

Description

This kit's Home automation and security system are designed with the idea to use the mobile handset as a long-distance remote controller. The mobile sets are now a day’s used most widely and very commonly. The SMS can be sent to any mobile user of any service provider with no or a minimum charge.

This Home automation and security circuit is designed using a GSM modem. The GSM modem is configured as a receiver. The SMS sent by the user is written in a particular format. The controller receives the message and decodes it and identifies the task to be done. The advantage of SMS-based control is as follows.

The Home automation and security system kit to control any device (on or off), we have to send just an SMS in a particular format, as soon as the SMS gets received by the microcontroller; it fetches the particular data from the SMS and controls the device accordingly. A proper message is also displayed on the LCD for the same (Optional). An in the device interfacing part we will be needed a relay for each device, and ULN2803 IC to interface those relays with the microcontroller. If some intruder is sensed by the sensor, then also an SMS is sent to the registered user.
