Automatic Switching Of Induction Motor Abstract:

INTRODUCTION:  Now-a-days, water crisis in India has been reached to alarm proportions and its wastage during transmission is identified as the major cause responsible for the problem. So in order to resolve the issue to some extent we have come up with Automatic switching of induction motor in houses, this project which is a simple model used to conserve water as well as electricity, and can be implemented in the real time work.

Automatic Switching Of Induction MotorEXISTENCE:

The basic idea for the project is water level indicating circuit. The water level indicator is operated with the help of IC 555 timer. The IC 555 timer is provided with inputs as soon as the level of the water in the sump or reserve tank reaches to a predetermined level. As soon as the water touches the predetermined level, the water level indicating circuit indicates its users by alerting through a beep sound.

PROPOSAL:

The above existed idea of water level indicator circuit is used twice to indicate the levels in the sump as well as the overhead tank and the output of the two water level indicators are given as the input signals to microcontroller. The Microcontroller is programmed in such a way that if water level is above the minimum water level in lower tank, water gets pumped to upper tank and as soon as the upper tank gets filled, motor switches off automatically.

TOOLS REQUIRED:

  1. Two water level indicators Software required:
  2. An overhead and underground tank Keil C Software.
  3. 8051 Microcontroller
  4. Power supply

  FEATURES AND ADVANTAGES:

  1. Constant and reliable water supply.
  2. Functions with minimal or no human interface.
    3. Easy maintenance; install and forget for years.
  3. Low cost and it is absolutely affordable by all.
  4. Prevents dry running of motor and so water, energy, power not get wasted.

APPLICATIONS:

  1. Monitoring and controlling of water level in reservoirs, dams are important in applications related to agriculture, flood prevention etc.
  2. Domestic, industrial, medical fields etc.

CONCLUSION:

The main objective of the project is to automate process of water pumping in a tank, ability to detect the level of water in a tank, switch on/off the pump. Hence from our proposal of “Automatic switching of induction motor,” water wastage gets controlled by constant and reliable water supply.

 RFID tags:

The data is transferred by means of RFID tags, the power for the tags are obtained from the electromagnetic field by means of micro chip. The voltage is caused due to the resultant interaction of RF fields at the transceiver antenna. This phenomenon is used for the transfer of data to the reader.
