Abstract

The Project is mainly to protect homes from rising threat of being robbed. It provides the ability to sense motion/activity in your home and alert you with an image of current status in your home. It also has the ability to sense if there is any kind of gas leakage and sends notification to you. The Project is also created with automation, which provides the ability to control your household electrical appliances through internet with password verification with SHA-256 Algorithm.

SMPS (Switched Mode Power Supply)

Specifications

• Input 220V AC/DC• Output 12V DC 2A

About

The Switched Mode Power Supply is a kind of AC to DC Buck Converter with transformer which reduces 220V AC Input Supply to 12V DC with the capacity to handle 2A. The main purpose of using a SMPS in this project is for the siren which requires 12V DC Supply. Which is in turn connected to the Relay.

Conclusion

The Project provides us the ability to control any house hold electrical equipment anywhere from the world. The Project is also focused on anti-theft & security to places that are prone to gas leakage , the device is equipped with the most advanced MQ-6 Gas sensor which detects smokes which are of commercial use in wide range of places. It also senses/detects activity around 20 meters from where the device is mounted. The user is notified through SMS & internet if any of these changes are detected in the preferred location. With prior to detection of motion user is requested to activate alarm through 4 digit passcode which is encrypted with SHA-256 algorithm.

The Project is aimed at providing global security to the upcoming generation with the power of Cloud & Electronics.
