How To Make Non Contact Voltage Tester (Wireless AC Line Detector)

Non-Contact Voltage Tester
Skill Degree: novice
Assembly Time:: about 30 minutes

Non-Contact Voltage Tester Strength can purpose harm or even can become the reason for death this is why safety needs to come first whilst running with electric devices or electricity. In this article, we will display you a way to design an easy green Non-Contact Voltage Tester by way of the use of transistors. You could construct this circuit with the aid of using easy additives and test the presence of AC voltages. You need no longer worry about getting zapped because it’s far a Non-Contact Voltage Tester


Introduction


Non-Contact Voltage Tester

In this contemporary age nearly every aspect we use with an electric current. Before running with AC items we need to verify that cutting-edge is not present where we work. So we use the tester, A Non-Contact Voltage Tester is a secure way to make certain that the AC strength is off.

In this project, we’ve designed a completely simple Non-Contact Voltage Tester Circuit with the aid of using transistors. We have used the handiest one form of the transistor on this mission.

Additives Required

For Non-Contact Voltage Tester


3 Transistors BC547 (NPN)
1 LED, red or any shade
1 Buzzer (non-obligatory) 3v
1 transfer big apple type
1 9V Battery or 3v may be used additionally or supply
1 Battery Snap
1 Case any plastic cover plastic cowl


Required Gear:


Soldering Iron
Solder
Drill and drill bits (for making holes within the field)
Copper cord
Cutters (for copper twine)
Adhesive Tape

The circuit design of Non-Contact Voltage Tester

Make an antenna with a small piece of copper cord and is attached to the base of the first Transistor (BC547). The antenna detects the magnetic discipline whilst we located it near AC gadgets like cables and switches and so on, it gets a small quantity of cutting-edge and turns on the first transistor through the base.

The output of the first transistor drives the second transistor, it gets activated and 1/3 transistor activated with 2nd transistors output. As the 0.33 transistor turns on, the LED is grew to become ON.

We can use the small buzzer in the vicinity of the LED. The buzzer will warn you through voice, Buzzer should 3 volts because we are using a 3v battery.

A way to function Non-Contact Voltage Tester?

Make the connections as consistent with the circuit diagram.
Join the battery to the circuit.
You could vicinity the circuit in the small field.
The area the antenna near to the electric appliances.
LED will run if the voltages are passing through the objects.

Applications

This easy Tester can be used in many places and near close to many objects like switches, cables, retailers, cords, junction boxes, circuit breakers, fanatics, vehicles, and so on.
You may make it transportable by way of fixing it into a small box.
