ELECTRONICS CIRCUIT FOR DETECTION OF ELECTRICAL ENERGY BY USING       MOBILE PHONE

This circuit is made up by the following materials:

i.                   Timer Delay Relay.

ii. Relay.

iii. One way switch one gang.

iv. Rectifier.

v.                 Indicator (Bulbs).

vi. Mobile Phone.

vii. Cables.

viii. Phone charger.

This circuit is designed for the purpose of detection of electrical energy by using mobile phone to gives information.

PRINCIPLE OPERATION

When the current flow pass through the mobile phone by using charging system in order to unlock mobile phone to start the operation. Also when power is on indicator (B1) show the presence of electrical energy.

After unlock the phone the current pass through Re1 and Re2. Then AC Voltage is stepped down to DC Voltage i.s 220V AC to 12v - 25v DC by using Rectifier. Then T1 and T2 start to operate mobile phone frequently it can redial more than four times, until operator has got the information.

ADVANTAGE OF THE CIRCUIT

i.                   Easy to control.

ii. Provide information in fast way.

iii. It protect Machines e.g. Generator.

iv. The circuit is light, portable and inexpensive.

v.                  It can be used in security system.
