Wireless AC Line Tester Circuit

 

Introduction:

                        This Circuit Project is “Wireless AC Line Tester”. This Project is used to wire’s working condition and wire’s phase identifier without touching the wire. It is very useful for the Electricians and Plumbers. It’s Total cost with battery is Rs.75 only.

Working:

                In this Circuit, we used the NE 555 Timer IC. This IC generate and detecting the Abnormal frequency. So, this circuit detect frequency via 2^nd pin of the IC. After, It Transfer the frequency to the 6^th&7^th of the IC detected frequency is converted into low intimation and it send to the IC. Then, IC emitted the voltage on output pin of the IC (3^rd Pin). Thus, the LED was glowing.

Part List:

1)  NE 555 IC=1

2)  8 pin IC base=1

3)  LED=1(any colour)

4)  10KΩ ¼ watt Resistor=1

5)  4.7µF/16V Capacitor=1

6)  Zero Board=1

7)  9-volt power supply

Uses of The Project:

                This project is used to detect the AC Line on wires in PVC pipes and Behind the walls. So, it is very useful for electrical works.
