Eltronicschool. - This is one of the detector circuit schematic for you that show you with building NE555 IC look like in Figure 1 below. The main circuit schematic here is NE555 IC.
Beside we will give you the circuit schematic of Non Contact AC Voltage Detector using NE555 IC, we also will give you the description of this circuit easily.
Circuit Schematic
Component Part
Circuit schematic like in Figure 1 above is Non Contact AC Voltage Detector using NE555 IC. According Circuitdiagram site describe that this is a very easy useful project of a non contact AC voltage detector circuit. The circuit will blink an LED and make beep beep sound when it detects any AC field. The circuit can be used to check AC voltage in wires, switches, plugs, wall sockets, electronic devices etc. without making a direct contact.
It will also show the phase and neutral wire from the two AC wires by making beep and blink LED only on phase wire and being in off state on neutral wire.
The circuit is using a 555 timer IC, a 2N3819 FET (Field effect transistor) with some resistors and capacitors. The 2N3819 transistor is working as AC field detector and the beeper circuit is built around the 555 timer IC.
The circuit can be operated from 6 to 12 volt DC. If you are operating the circuit with lower voltage then change the LED current limiting resistor according to the operating voltage to brightly blink the LED. On six volt you can use a 270 ohms resistor, On 9 volts use 320 ohms and on 12 volt use 470 ohms.

ReplyDeleteMobile Air conditioner is a compact, stylish, and powerful AC unit that plugs into a standard power plug for instant cooling. Mobile AC is the best solution for cooling any particular area quickly and conveniently. As Mobile Ac does not require any installation, movable AC has become the most sought after air conditioners in India for customized cooling and heating solutions.
