2B-TANK MOTOR CONTROLLER
Now-a days, in factories as well as houses, the over flowing of water tank creates a problem. The water over flows and spreads here and there. This project can solve this type of problem.
TECHNICAL DESCRIPTION AND WORKING
This project has been develped and successfully tested OK at TV Engineers Technical Lab.
As shown in the diagram below,attach the senser to the tank. Take two insulated material(e.g plastic) stick. Attach length copper wire to one stick and make two points (top and bottom) on other stick with copper wire;and mark them point A,B,C as shown in the diagram. Connect points A,B AND C to the main circuit . The IC 555 is used in the circuit as an astable multi vibrator . The IC is a 8 pin duel-in -line IC. When there is water in between the points A AND C, pin No 3 votage of the IC becomes high and transistor BC 148 operates the relay. As a result the motor starts and fills the tank. When the volts reaches the top level,A comes in contact with B and pin No3 voltage becomes low. The relay then changes the position and motor becomes OFF. When the water level becomes low, the motor starts again.
PRECAUTIONS WHILE ASSEMBLING
1.First of all cheak all the components as per the circuit.
2.The PCB prints should not touch each other. To avoid short circuit,be careful mole soldering
3.Use IC base while mounting IC
4.Use resistors of correct value as shown in the circuit
5.The insulation of the wire inside the modes should be of good quality
