MAN HOLE OPEN DETECTOR AND TEMPORARY PROTECTION EQUIPMENT

                                          FEATURES:

 1. Most economical than using sensors

2. Can be operated at any conditions.

 3. Quick operation without any time delay.

 4. When a fault occurs, the system alerts both in control unit  and surroundings of  the man hole.

 5. Less power consumption 

APPLICATIONS:

This project involves simple electronic equipment NOT GATE LOGIC INVERTER 7404 IC.When the input of the IC is less or zero it feds the system with high output and vice versa. In this module man hole placement ring acts as a conduction path for NOT GATE LOGIC. If there is any disturbances or damage and displacement of the top cover occurs the conduction path breaks and the logic circuit gives the output to the indicators and protection equipment. Protection equipment can be extended as per our requirement. Thus this project monitors man holes and prevents many of the accidents.
