How to build AC Line Current Detector - circuit diagram

Current is detected by passing one of the AC lines through an inductive pickup (L1) made with a 1 inch diameter U-bolt wound with 800 turns of #30 - #35 magnet wire. The pickup could be made from other iron type rings or transformer cores that allows enough space to pass one of the AC lines through the center.

How to Build a Current Sensor Circuit

A current sensor circuit is a circuit that can sense current going through it. If the current reaches a certain threshold, then an indicator, such as an LED, will turn on. This is not an ammeter circuit, where we know or are measuring the amount of current going through. That's a different thing entirely.

Alternating current - Wikipedia

The abbreviations AC and DC are often used to mean simply alternating and direct, as when they modify current or voltage. The usual waveform of alternating current in most electric power circuits is a sine wave, whose positive half-period corresponds with positive direction of the current and vice versa.

Using Hall Effect Sensors Detecting Alternating Current

Using an AC magnetic field simply produces about a 4-volt peak-to-peak sine wave (at maximum current) centered at 2.5 volts. Connecting a DC voltmeter will read only 2.5 volts, but on the AC setting one can read say 1.4 volts AC at best. None of this is very good.

How to Build a Simple Non-Contact AC Voltage Detector ...

Our domestic AC mains (house wiring) voltage is made up of alternating currents that keep shifting phase from positive half cycle to negative half cycle. This happens very fast, normally 50 to 60 times per second. Due to this rapid alteration in its phase, alternating currents generate a fair bit of electrical disturbance in the air.

How to detect AC voltage (not measuring)

Mains Voltage Sensor Circuit - ElectroSchematics.com

When AC mains input is available, the resulting input on the base of T1 through PC1 causes T1 to be driven into conduction by the current through PC1 and R4, thereby giving a ‘low’- level signal at the open-collector output of T1, if suitably interfaced to an external circuit with a pull-up resistor. In case of a power-down, the same is indicated by a ‘high’-level signal at the ...

Considering the "observer effect", what voltage drop is permitted in the detector. If order of current is in the milliamp range and you can afford to drop a volt or two, a pair of photo-couplers with the photo-diodes wired back to back(and suitable current limiting) will give you a logic output for either direction. I used to use this for testing for reversals in telephone circuits (detection ...

DCC - Current Sensing - trainelectronics

This sensor detected the current drawn when a 2k resistor was put across the track. That makes it a simple matter to add a resistor between the wheels on a piece of rolling stock to keep the block detector active as a train passes through it. Adding a light (an LED and a 470 ohm resistor) to a car would work, too. This is one of the test circuits that I built on a prototype board. The coil ...
