Hello, awesome video! Do you know how I can turn this into an ignition circuit for a homemade engine? The hall sensor circuit is good, but do you know how I can connect an ignition coil for a spark plug? 😀
Nice video, thank you sir. I am a hobist, I am trying (I am designing the circuit now) to drive an H bridge (2 X IRF4905 and 2 X IRFZ44N) with TWO HALL sensors, giving the GROUND OUTOUT of the Hall.. to the BRIDGE. Can I use this arregement OR something similar ?? ... what else have I to use.. to be suitable for the H BRIDGE ? Thanks a lot.
Easyandworkproject thank you another question. Can you make a printed circuit with all components attached I need to buy 10 boards. Please let me know the cost if you do. I am not good at soldering and circuits.
Hi, I like to use this hall sensor as a switch to an IRFZ44N mosfet. How can I wire this so that when the magnet passes by the sensor the Mosfet turns on, otherwise it is off. ( With the set up I have at the moment, the FET goes off when the magnet passes the hall. I have the hall's output go to the gate and also I have it connected to the positive rail with a 1K resistor)
@@Easyandworksproject Yea you said that. So the output of the Hall in default state is positive ( pull up resistor) the P mosfet is off ( opposite of the N mosfet) and then when the magnet passes the hall, its output is grounded/shorted/low, that will turn on P mosfet ( opposite of the N mosfet which turns off). In other words, is that what you are saying or you are saying something else, beside "use P mosfet". And where it says Drain on the leg of the P mosfet instead of hooking it up to the positive of power supply, I hook it up to the negative and where it says source on its pin I connect that to the positive side of the power supply...the opposite of N channel. or that is incorrect. Or do I hook up the pins of the P mosfet just like N mosfet, that is source to negative and drain to positive. I know you had no desire to clarify all this. I understand, it is dam time consuming. But I bet a diagram would take less than 5 minutes with no words spoken. And I keep the hall sensor in the same configuration. PUll up resistor to the positive of power supply with a 1k resistor.
@@Easyandworksproject I think I may have this figured out. The P channel mosfet the drain goes to ground and the source goes to the positive rail, the opposite of the N channel. So the Hall sensor held so called high with the resistor keeps the P mosfet off as the base/gate is positive and the source being positive. When the magnet is by the hall, its output gets at ground level and that will cause the P mosfet to conduct. The current from source can move through the gate since the gate is ground low voltage. Can't get lower than ground.
I want to sense 12V DC current through a wire (on a motorcycle). How strong of "magnet" is required? If I lay the A3144 sensor against the wire, is it sensitive enough to detect the magnetic field and turn on?
Yes just what I am looking. Except I need to turn on a 9V@500mA solenoid So I am wondering can I use 5V for the VCC and 9V on SOURCE pin, and the solenoid between DRAIN and gnd?
In lieu of magnets, hall sensors could also be used to detect DC current flow in a wire? (e.g. contactless detection to trigger a relay); Potential application: "strap" hall sensor to wire that is to be detected (heatshrinking may damage hall sensor)... typical 12VDC automotive relay has a coil winding resistance of roughly 80 Ohms, giving 150mA current (1.8W), "passive" control of said 12VDC relay... up 20A (12VDC) current switching.... kinda-sorta like a reed switch. As Hall sensors are "fast acting", I came here in search of measuring/displaying AC current output of the individual - pre-rectified - phases of a 3-phase (motorcycle) alternator; alternator current output is roughly 20A (240W), voltage output is roughly 12 to 15Volts... AC current output frequency is estimated to be between 16 and 300HZ... it is very difficult to find digital AC Ammeters that operate in this range (FWIW, this will be installed in a fixed, instructional display...not in a car or on a motorcycle)... this posting is intended for those that understand this better... and may have some recommendations on applicable components/schematic. (wondering about using BJTs (2N3055?)
Dc current make very small magnetic field in a wire and it not enough to trig the hall sensor. If you want to detect dc magnetic field, you may need analog hall effect sensor.
Bjt has low input impedance, so I use mosfet because a mosfet use very small input current, that make hall effect sensor temperature low when it turn on.
How about if I want it in reverse, I mean I'd like the fan to run when there's no magnetic field? In other words I want the magnet to turn off the fan.
Hello Nice video is it possible for you to make me 10 of this in a neat package. I want to use it to led strip. Please let me know the cost. Circuit board needs to be small and neat. Thanks Ajay
Sorry, I don't make pcb board but you can make it by find online PCB design. A3144 is very low cost and you can use smaller size mosfet if you use it with led strip.
Easyandworkproject thank you very much I have a hard time reading the little script it's on my cell phone so that's probably why I didn't recognize the values of the resistors you have yourself a nice day

Thanks for taking the time to make this video! I'm using the circuit in a project now.
Great!!!😊
Hello, awesome video! Do you know how I can turn this into an ignition circuit for a homemade engine? The hall sensor circuit is good, but do you know how I can connect an ignition coil for a spark plug? 😀
Mayby I connect the output from the transistor directly through the coil to the spark plug?
You can but you need to use output to trick the ignition circuit.
@@Easyandworksproject So I just wire directly from output on the transistor to positive on the ignition coil?
No,output from hall effect doesn't has power enough to drive ignition coil directly.
I need to know the coil datasheet before answer you.

Ok I find the circuit now. You can use the hall as my video. Build it and ask me if you have anyproblem.
thank you so much .from Algeria
You're welcome.
nice and clear schematic!thanks.
Thank you.
Thank you very much for this video!!!
You're welcome!!! Enjoy your electronic hobby!!!
I like your incredible easy project and diagram video
Thank you.😊
please more easy project video
please make a digital led display clock
It's is easy with Arduino but I don't have real time clock module😐
please make a emergency light
Hello exactly what I was looking for thanks. Just a quick question can I use this power 12v 2amp. Led strip light.
Sure, Irf 540 can handle it, attach small heatsink if you plan to use more power.
Easyandworkproject thank you another question. Can you make a printed circuit with all components attached I need to buy 10 boards. Please let me know the cost if you do. I am not good at soldering and circuits.
Sorry, I don't do pcb work. You can find it on google search.
Easyandworkproject thank you for all your help
What changes should i make if i am using n channel mosfet?
The circuit should be use p channel mosfet because a hall effect sensor output low when detect magnetic field.
@@Easyandworksproject ok thankyou i used a p type transistor in between n mosfet and the hall sensor that should work.

Use p chanel mosfet.
@@Easyandworksproject You mean all the other component and circuit wiring remain in the same configuration?
No, you need to send output from a3144 to p channel mosfet.
@@Easyandworksproject Yea you said that. So the output of the Hall in default state is positive ( pull up resistor) the P mosfet is off ( opposite of the N mosfet) and then when the magnet passes the hall, its output is grounded/shorted/low, that will turn on P mosfet ( opposite of the N mosfet which turns off).

I will test it when I come home😉
The hall effect sensor a3144 not sensitive enough to detect small dc current🙁
Yes just what I am looking. Except I need to turn on a 9V@500mA solenoid So I am wondering can I use 5V for the VCC and 9V on SOURCE pin, and the solenoid between DRAIN and gnd?
Yes!!! It will works.😊
A 3144 hall effect sensor can works with 9 volts vcc, so you don't need a separate powet supply.😁
I need 5V VCC for a digital logic circuit that controls another 9V device.
Also I want thank you for the quick response
Ok, I got it!!!
You're welcome.
Please tell me any other similar mosfet
Any PNP MOSFET is ok.

Connect ic output to arduino analog input.
@@Easyandworksproject would I still need the resistor there?
Yes.
It is pull down resistor.

I will answer you when I come home😉
That's really kind of you!

Can use BC547 transistor and TIP42C transistor
Yes, you can😀
Without resistor, can or not
I only have TIP42C transistor only and a3144 hall effect sensor
Yes, but TIP42C current gain around 100.
No.😅
Big like 👍 👍 👍
Thank you.
I apologize for my ignorance but where is the value for the resistors
