A true Smart Home is one that seeks to take full

advantage of Smart technology within a wider, yet

focused, specification allowing service providers and

occupiers to benefit in many ways - from convenience

and better living standards to energy saving and device

communication. The house is also economical.

Automatic LighteningIn this system whenever a person enters a room the light automatically turns on

and when the person moves out the light turns off.

Functioning

For this we have used a simple on and off circuit.

There is a wire at the back of the door. When the person pushes the door the wire

comes in contact with another wire present on the wall. This completes the circuit

and the bulb glows.

When the person comes out and closes the door the wire detaches and the bulb stops

glowing.

Regular Energy Consumption Monitoring

This system gives hour by hour details of electricity

consumption by different appliances in different rooms

of the house.

This helps us to diagnose the wastage of electricity in the

house and accordingly take necessary steps to reduce the

wastage.

Solar Water HeatingA black tank with glass covering is placed in east

direction.

Scientific Principle Used:

Black color is the best absorber of heat. The

container receives the light directly from the sun.

The black walls absorb the light energy of the sun.

Due to the presence of glass greenhouse effect

takes place. The heat of the sun is not allowed to

move out. This heats the water.

Light Sensitive Bulb

It is often observed that lights of backyard, car sheds ,storehouse etc

remain switched on by mistake even during daytime.

This results in wastage of lot of electricity.

So we have used a light sensitive bulb in our car shed. When there is

dim light the bulb automatically switches on and when bright light

falls on it ,it switches off.


9/31

Functioning

Light dependent resistor(LDR) is used to

sense the ambient light level to switch the

triac on or off. When light falls on the LDR,its resistance becomes so low that the voltage

drop across it is negligible and the voltage at

pin2 of the IC is little less than that of the

supply.

Water Conservation Measures

Rainwater harvesting

Grey water harvesting


12/31

Rainwater HarvestingRainwater harvestingis the accumulating and storing, of

rainwater. It has been used to provide drinking water,

water for livestock, water for irrigation or to refill

aquifers in a process called groundwater recharge.

There are two types of rainwater harvesting system-

Rooftop

Groundwater recharge


13/31

Rooftop Rainwater Harvesting

Rooftop Rain WaterHarvesting is the

technique through whichrain water is capturedfrom the roof catchments

and stored in reservoirs.


14/31

Groundwater RechargeHere the collected water is taken below the

ground to recharge ground water


15/31

Greywater Harvesting

It refers to using of wastewater from kitchen and

bathroom for various purposes such as irrigation.

This method reduces wastage of water in irrigation

of kitchen garden.

17/31

Thermal Chimney

The solar chimney consists of a black-painted chimney

or basement. During the day solar energy heats the

chimney and the air within it, creating an updraft of air

in the chimney. The suction created at the chimney's

base can be used to ventilate and cool the building below

. Generally trees are planted at leeward side.

Use of Hollow BricksHollow bricks are used to maintain temperature of the room.

Working principle-

Air is a bad conductor of heat. During summers hollow bricks

containing air do not allow heat from outside to enter the room.

During winters they dont allow the heat from the room to go out.

In both these cases it maintains the temperature of the room.

Security System

Burglar alarm

Fire alarm


21/31

Burglar Alarm

It is an electronic device which starts ringing

when the copper plate is touched.

This has been placed under the doormat of the

main gate of the house.


22/31

FunctioningThe circuit comprises of two stages.

The first stage having t1 and t2 transistors forms the triggercircuit. When the copper plate is touched, the transistort1

conducts and produces feeble pulses which are amplifiedby t2.

The second circuit is an audio oscillator made by t3 and

t4.The signal from the trigger part becomes an audio signalwhich is converted into sound by the loudspeaker.

Fire alarmThis alarm starts ringing in case of fire.

Functioning-

Here, an IC based fire alarm is described. This circuit is made

around 555 IC (timer). A reverse biased germanium diode is usedhere as heat sensor.At room temperature the diode has very high reverse resistance (over 10 k ohm). No effect is produced by it on transistor T1 whichconducts and beeps the reset pin 4 of IC -1 at ground level and sothe alarm does not sound.

When temperature in the vicinity of diode D1 (the sensor) increasesin case of fire, the reverse resistance of D1 drops. At about 70 degreecentigrade its resistance drops to a value below 1 k ohm. This stopsT1s conduction, the Ics reset pin 4 becomes positive throughresistor R2,which sounds the alarm

Positioning Of Rooms Positioning according to Indian Vaastu.

Bathroom on east side for proper sunlight

Isolated bedroom in north west direction withsound absorbing material

Kitchen away from bathroom for proper hygiene

Ventilated bathroom and toilet

Location of kitchen near the main door

Some New Features

Energy saving utensils.

Insulation of pipes and location insidebricks.

Planting of mosquito repellent plants.


28/31

Energy Saving UtensilWe have created a special type of utensil

which saves a lot of LPG.

Functioning

The utensil has a 2in1 structure. It contains

two utensils piled over on another. So at the

same time you can perform cooking of two

substances. It utilizes the heat from the

steam of the utensil which is placed below.

For Eg-You can make tea and boil milk at

the same time.

Mosquito Repellent PlantsSome plants have natural mosquito

repellent properties like marigold, garlic,neem,tulsi.

We have planted these trees outside thehouse to reduce mosquitoes.


30/31

Plumbing Design To Provide Cool Water in Summer

In our house we have made our tank with light

colors. Also the pipes are placed inside the

house and are insulated so that the heat from

outside does not reach the water and heat it.
