ULTRA CHEEP HOME AUTOMATION UNDER $5

Hello friends

Today I am back with another project called ultra cheep home automation under $5

Home automation means you can control home applies more easily. You can control your fan lights exits’ with tip of your finger or allow them to work automatically

The project contains three different switching circuits

1. IR remote controlled switch

2. Automatic water level controller

3. Automatic night light

Step 1: My Goal

“To make a cheap and efficient home automation circuits under $5”

Step 2: The Circuit :IR REMOTE CONTROLLED SWITCH

This is the driving circuit of the IR remote controlled switch

To make this circuit you need

1. BC 547 & BC 558 Transistors = 9 INR

2. CD4017 IC & 16 Pin IC holder = 15

3. TSOP 1738 = 17

4. 100 Ohm resistor = 0.50

5. 100K Ohm resistor = 0.50

6. 4.7 K Ohm resistors x2 = 1

7. 10uf Electrolytic Capacitor = 10

8. 0.1uF Film Box Capacitor = 5

9. 1N4148 Diode High-speed diode = 2

10. 5V relay = 20

11. 2-Pin PCB connector x2 = 10

12. Wires = 5

13. PCB = 10

Total = 105 INR

Total cost of this circuit is equals to 105Rs or 105INR (70 INR = 1 USD).that means this circuit is under $5 budget

Step 3: The Circuit :AUTOMATIC WATER LEVEL CONTROLLER

This is the driving circuit of the Automatic water level controller

To make this circuit you need

1. BC 547 Transistor X 3 = 9 INR

2. 220 K Ohm & 5.4 K Ohm resistors = 1

3. 1N4007 Diode = 1

4. 12V relay = 12

5. One, 3-pin PCD connector & two, 2-Pin PCB connector = 25

6. Wires = 5

7. PCB = 10

Total = 66 INR

Total cost of this circuit is equals to 66Rs or 66INR (70 INR = 1 USD).that means this circuit is under $5 budget

Step 4: The Circuit : AUTOMATIC NIGHT LIGHT

This is the driving circuit of the Automatic night light

To make this circuit you need

1. IRFZ44 MOFSET = 17 INR

2. 150 K Ohm resistor = 0.50

3. LDR = 2

4. 1N4007 Diode = 1

5. 12V relay = 12

6. 2-Pin PCB connector X 3 = 25

7. Wires = 5

8. PCB = 10

Total = 72.50 INR

Total cost of this circuit is equals to 72.50Rs or 72.50 INR (70 INR = 1 USD).that means this circuit is under $5 budget

Total cost of the these circuits are under 5$ budget

Step 5: Fitting and Wiring

IR REMOTE CONTROLLED SWITCH need an 5 V DC to operate.you can use any IR blaster as switch

AUTOMATIC WATER LEVEL CONTROLLER need 12V DC to operate.you can control any water pump Max load is 1.4kW).use stainless steel bolts as sensor

AUTOMATIC NIGHT LIGHT need 12v DC to operate

Step 6: The Moment of Truth

Sorry im a newbee. Where do i connect this switch? Am i gonna tap it to the wire of the appliance im using?

[vina1991]

like this

[vina1991]

it's a switch.you can replace any ordinary switch with this IR switch

[wreckekek10]

Hi. I have a question. What are the other things that i can connect to the ir remote controlled switch?

[vina1991]

any thing under 4Kw :)

beware!! not use with any device that use an IR remote

[wreckekek10]

Where do i put the 5v dc?

[vina1991]

put 5 volt hear :)

[beardoo]

Hi, im new in electronics and i have a question, maybe is a fool one, but what am i have to connect to ve+ and ve- ?

[vina1991]

+ve means positive. usually a red or white wire & -ve means negative. usually a black wire.use a multimeter to ensure the polarity

IR REMOTE CONTROLLED SWITCH - 5 VDC

AUTOMATIC WATER LEVEL CONTROLLER - 12VDC

AUTOMATIC NIGHT LIGHT - 12VDC

[vina1991]

Yes You Can!

TSOP1838 and 1738 are same.18 series comes with small size package

[SasukeU]

Can I use TSOP 1838?

[tn.]

What a great idea! I'd put circuits for all lights in the apartment on a board in direct sightline to the entrance so when i leave or enter, it's one click to kill or activate all lights. Great for families whose kids keep forgetting to shut off the lights and those who have anxiety disorders.

[tn.]

Also, the water controller would be a terrific backup for a sump pump or a painless way to maintain aquarium water levels.

[vina1991]

i don't know the the water level controller is safe to fish.but i know it's not harmful to human because i am still alive ;)

[tn.]

Generally speaking, stainless is safe for freshwater fish.

Saltwater might be a different story, however, since salt is corrosive and also changes the conductivity of the water. I have zero experience with marine tanks, so perhaps someone else can chime in.

[fred_]

It's probably not the best circuit for a few reasons. You'd probably get corrosion where the copper wire attaches to the bolt. A DC current is likely to corrode the ss bolts and would make a small amount of chlorine. Chlorine and copper are two things you'd want to keep away from a marine tank. You could probably use a cheap pressure sensor and a pic/duino etc to analyze rational level measurements and other logic tests to trap system failures. That way you'd only have a plastic tube exposed to the water with the electronics away from the moisture/salt. Might be $10+ range though.

Great! ?

[vina1991]

WHAT "?"

Thank you for your comment :)

[Raphango]

Sorry, this "?" is a emoticon from my phone hehe

I really enjoyed the water level controller, electronics is a world class hobby that needs projects like this to spread the joy of being able to actually fix things. ebay has some fantastic bargains on electronic relays capable of handling 20, 40, even 100 amps of ac (triggered by 3-to 36v dc)at low prices. i do a lot of simple projects living in the country , and used the water level controller on my evaporation cooler . they have a little float valve that gets plugged easily and floods the ground or goes dry and quits cooling. I substituted the water inlet valve (110ac) from a discarded washing machine for the pump and solved the problem. While relays can be salvaged from automobiles where they control fuel pumps and lots of other items,(0$ cost), the solid state stuff will last for decades... if the electrical storms and tornadoes don't get them first, .... i live in Oklahoma! thanks for doing what you can to make electronics useful to ordinary folk who are missing out on a great hobby.
