How To Non Contact AC Wireless Detector DIY
In this video we’ll make a simple wireless PC tester, which then we did the live and so this project will be very helpful to detect live and neutral work in your home. And if you enjoyed this video, of wireless PC tester. It consists of three transmitter which is specified for seven npn transistor, and the value of a study is 120. And there is an LED to indicate live and neutral and will separate the circuit with the nine volt battery. Now, there is a switch which, if you want you can use it as will make the circuit on the breadboard will not use this switch. Now first applied and divided three terminals of this transistor DC five foot seven. Now, I have placed the car portion in the side. So the terminal will be from the site collector base and emitter. As you can identify this T terminal of the transistor. Now I’m going to place this transistor on the breadboard. So you can see I have placed one transistor on this breadboard pieces connector base, and this is. Now, same way. Other transistor can see the tree transistor.
In the same manner. On the car portion in the side. Now you can see I have placed the r1 register which is one mega ohm resistor. With the connector of the first transistor and positive eight. Now you can see I have placed the second raised, which is 100 K. With the collector of the second transistor and the positive rail of the breadboard. Now this is a transistor, which is odd people don’t do I placed a register with the conductor of the transistor. And another of the breadboard cathode of the LED will be connected. Now, this is a led the red LED is the anode and cathode. Go to the positive. And we’ll connect the cathode, which is. Now you can see I’ve connected the anode of the LED with the positive rail. And I’ve connected the cathode of the LED with another formula. I’ve connected. The first transistor with the base of the second transistor connection. You can see a meter of the second transistor is connected with the base of the transistor.
This will act as an antenna to since the neutral or Livewire. Now our circuit is ready to be supplied with a nine volt battery. Now you can see I have connected the battery connector with this breadboard, the positive terminal of the battery will go to positive rail of the breadboard and negative terminal of the battery will go to emitter of the transistor. As you can see, this is our emitter of the canister. And this is a positive rail does complete the circuit. Now, we’ll place the battery, and see how this circuit work. Now I’m using both sides, tape to place this battery on this breadboard. Now, our wireless AC detector circuit is ready. We can test it right now. Now we are going to test this wireless AC tester for that I have connected this AC lamp, and these two were with this plug point. Now, as this is in turn of condition, if I take this antenna close to this where you can see the LED is not going.
And same for these two were also, as no current flowing through this web. Now if I turn on this lamp, you can see as soon as I turn on the lamp. The LED start glowing, as it sensing current through this work. So, it can easily sense whether the current is flowing through this wire or not. Now, if I take away the antenna from this where you can see the LED struggling. Again I’m taking closer to this where the LED starts flowing. So this is a very helpful wireless tester, which you can use in your home. Now we have to identify the neutral and library with this tester. So for that, I will use these two where one of them is live and one of them is neutral. So, we can easily identify it with this tester for that I have to take closer, this antenna, with one of these two wires. You can see for this red dial it is not going. So this is neutral. And for this, if I take the antenna closer to this where tallit start glowing. So, this is live with this we can easily identify an internal library in every circuit with this tester. Now if I talk about the warden principal officer key.
First, when we take this antenna close to any current carrying conductor, a small current induce English copper wire, which can only stand disturbed and current can flow collector to emitter, the emitter point of this first run is 31. We’ll turn on the second transistor T two. So, current can also flow through this T two. And this emitter current of T two transistor will turn on this TT transistor. Now when these tea tree turn on and can flow through this LED. So led start blowing. So, this mall induced current amplified by D street transistor, and which Hill. This led to flow as soon as it sends any current carrying conductor. Does this circuit work to sense any current carrying conductor. I hope this is very helpful project, you can easily identify it and you can live well in your home, and it is also very safe to use as no party is connected with the light system.
