To develop security system for houses and to save electric power.
Scope: This project and implimentation proposes the development of security system for farm houses and residential houses.
In an extremely mechanized world such as today’s it is necessary to make our life better, convertible and economical. This is the purpose for which the Electronic house is developed.
Electronic house consists of six major units.
1. Remote operated gate control
2. Automatic gate light, call bell system
3. Auto adjustable timer unit
4. Remote operated electrical equipments
5. Touch sensitive burglar alarm for internal security
6. Water level indicator and controller in a tank
Remote operated gate control:
This unit is responsible for opening and closing the gates at the pressing of a button on remote transmitter.
Automatic gate light, call bell system:
During day time, this unit generates a musical alarm, when anyone entering the compound of the house. During night time, at the entry of any person through the gate, the compound lights are switched ON together with musical bell.
Auto adjustable timer unit:
This unit can be used to operate an electrical equipment for a fixed period of time. The circuit can be used for street lightning, billboard illumination and water supply to the garden where pump can be set to switch ON at one time and switch OFF at another tome.
Remote operated electrical equipments:
This unit replaces the conventional switchboards. Fans, lights and other equipments can be operated and controlled using remote controlled unit.
Touch sensitive burglar alarm for internal security:
This simple circuit when connected to a metal locker or cupboard generates an alarm when touched by an undesired entity.
Water level indicator and controller:
This indicates the water level in the water tank at four steps F, H, L, E, i.e., Full, Half, Low, Empty. When the tank is empty the unit automatically switches ON the water pump and switches OFF when the water level reaches to full.
This electronic circuit explained above is only a model, and incorporated in a cardboard model house. These circuits can be incorporated, and realized in a large scale.
All the above circuits are explained in the following pages.
