SMS and Microcontroller based Smart Home Controller
The objective of this project is to improve the security performance in the house and to control the home appliances through mobile. This project is designed with Microcontroller, Flame sensor, Gas sensor, IR transmitter and receiver, signal conditioning unit, RS 232, and Data cable with mobile.
Flame sensor is the one type of transducer which is used to sense the flame. If any fire happens in the house the flame sensor will detect that one and send the signal to microcontroller through signal conditioning unit. Gas sensor is also one type of transducer which is used to sense the gas leakage in the house. If any gas leakage in the house it will sense that leakage and send the signal to microcontroller to signal conditioning unit.
Infrared transmitter and receiver are fixed in the entrance door. Initially the infrared transmitter transmits the rays to the receiver. If any one crosses the rays it sends the signal to microcontroller through the signal conditioning unit. Similarly the door breaking sensor is fixed in the entrance door. If any person breaks the door, the sensor will detect the vibration and send the signal to microcontroller through signal conditioning unit.
The signal conditioning unit is constructed with operational amplifier which acts as comparator. It receives the signal from all above mentioned transducer and generates the square pulse. Then this square pulse is given to microcontroller. Here the microcontroller may be Atmel or PIC both are flash type reprogrammable microcontroller in which we have already programmed with desired phone number.
The mobile phone is interfaced with microcontroller through data cable and RS 232. RS 232 converts TTL logic to RS 232 logic. If any one transducer is activated due to that corresponding microcontroller sends the related information to the mobile phone. The mobile phone sends this information as SMS to desired phone as per the phone number stored in the microcontroller.
