Automatic Water Level Controller

• The one described here is built around timer NE555 and inverter buffer CMOS IC CD4049.
• It uses readily-available, low-cost components, and is easy to build and install on the over-head tank (OHT) to prevent wastage of water.
• The circuit works off a 12V battery or 230V AC mains using a 12V adaptor.
• The three sensors built from non-corrosive metal are fitted to the over head tank to prevent wastage.
• As water is consumed and its level falls below sensor,the motor restart.
• Also can manually start and stop motor using switch.

SMART SINK

Specificatian :-
- This Smart Sink have 3 pipe  that function using motion sensor.
- Every pipe have its function, the function of the first pipe is flow out the water,
   the soap and the last pipe operate to dry the hand.

-  I made this project for help people easy to clean their hand because our      

   product will flow out water, soap, and dry the hand automatically.

-This product also save  water because it control by the sensor.

Hardware and Software :-

- PIC 16F87X 28/40-Pin 8-Bit CMOS FLASH microcontroller

- DC Water pump motor

- Infrared sensor

- Transformers 240V to 24V

- C coding, Protues

Electric Cook

This project involves making an electric device which functions to cook rice, cuisines, deserts etc. The cooker's functionalities and benefits are:

-Use electricity to heat
-Adjustable temperature
-Set timer
-Set temperature limit
-Cooking faster
-Auto-stir
-Safety
-Mobile (friendly especially for college students)

Active Voice

I came up with this idea of activating almost every electrical items in a house (or maybe just a room) -eg: lamp, fan etc- via some sort of a voice recognition system. I'm not quite sure about the costs and sensors required to accomplish this but perhaps, it may need a few sensitive voice detectors (microphones). This system works just like the voice recognition software used in OS Windows Vista and se7en.
