Hi there sir! i want to make a dc motor(25000 max rpm) rpm measure device. which sensor would be best for this range linear or non linear or bipolar. i dont know quite about this. i just heard that 3144 hall effect sensor work at low and high scheme and what type of sensor is this linear , non linear or bipolar. so would it be best for making a rpm measure device?
Hi, here read about the 3144 on the datasheet www.elecrow.com/download/A3141-2-3-4-Datasheet.pdf it is just a sensor. it is up to you to use as RPM counter or other application.
hi, can you help me please. i want know the units that use this Sensor, when i measure the magnetic field i see that when the sensor unaffectedly is 512 i use the sensor hall 94E but i don't understand the units that use and how i can messure the magnetic field in tesla
this is not precise. It is to demonstrate. Read the data sheet please.
Any way to use this to count magnets on a floor? say to guide an agv when it arrives to a number 3 as example it could turn 56 degree's and then when it hits magnet 4 it turns 34 degrees?
nice video, can this sensor be used to build a gaussmeter? o should i need i different module?
I am not sure because this works best with metal. but here is gesture sensor video th-cam.com/video/wH9HpP9bKwE/w-d-xo.html
Sir I'm working on project using hall sensor, 16*2 lcd, and relay for operating 2 way solenoid valve. hall sensor will convert the rpm of wheel into kilometers and at particular kilometers solenoid should open will you please share circuit diagram and code for this project. I'm beginner in arduino
Hi, This is a project and needs lots of work which I have no time for. May be someone else replay and help.
Thank you for a good explanation of how this sensor module works. Can you get the sensor by itself? It is very small compared to the module board.
the signal from receiver is being amplified by the op-amp chip. You won't get the same result with Ardouino.
This is good sir, thank you so much.
You are welcome.
Do you need an Arduino for each limit switch/Hall effect module? Thanks
You can connect multiple hall switches to the same arduino. But if you want to use them separately you need to use an Arduino board. Or you can use digispark board th-cam.com/video/eW9WgPlcPAw/w-d-xo.html
Thanks for detailed video, what to do if we want to switch on the buzzer while magnet is not near the hall sensor or its on the sensor switch.
you are welcome. Please watch this video to turn ON or OFF a buzzer th-cam.com/video/46Z-6MVxKnc/w-d-xo.html just watch and see how it work, and use the same method with hall sensor
@@robojax thanks a lot
you are welcome.
If I have conductor connected to the source (with resistor of course), how many ampers will I need to detect electromagnetic field by this Hall effect sensor?
Hi, I've provided the datasheet robojax.com/learn/arduino/?vid=robojax-hall-sensor on the page where the code is. the supply current can be 4-6ma shown on page 6
Can i used this sensor on an anemometer to measure wind speed?
if you know how to use it, yes. you would some rotating object with certain surface area and number of blades. Then you have magnet in one of the blades and this sensor is at the proximity of the blade detecting the magnet. you would have to make the delay in the loop to 1 delay(1) which is 1 millisecond or remove it completely if your application needs faster result. remove any serial monitor printing as it will slow the loop. good luck. I have not made any device like that but I believe that is the main principle or at least I will do it like that.
@@robojax thanks a lot
Can you do a video making a Hall Effect analog (or digital) module with the Arduino powering 10 LEDs, with each LED indicating the distance to the magnet as it passes the sensor?
that is possible and very interesting. I have to look at the components and make it. I will put it on my list. thanks
, Arduino has an example “LED Bar Graph”. The Arduino has 10 LEDs plugged directly into it. The LEDs are powered on one at a time using an analog signal from the potentiometer. I’m wondering if a guy swapped out the pot and instead used a KY-024 Hall Effect sensor using its analog output. Wouldn’t the KY-024 analog out (A0) signal from the KY-024 be doing the same thing as the potentiometer (1K or 10K???), except rather than turning the pot knob you would be moving a magnet across the KY-024 path. Would this work?
I have several LCD bargraph. search for them on my channel.
in theory, yes. but I don't know if the hall affect outputs analog signal and IF it is proportional to the input flux or magnetic field.
Yes, this particular Hall effect voltage output is directly proportional to its distance from the sensor, at least theSS49e is. That is why and how the LED dims and brightens when the magnet is pulled in close or pulled away. There are some hall effect sensors that only toggle off and on, some that latch, and some that are like the 49e.
I will see what videos you have. Thanks for your help.
hi, i need your help. how to do stepper homing system. Please give me complete detail. I don't know much about this process but if you help me then i can do this. Thanks
Hi, here is the best video on using stepper motor th-cam.com/video/cYTICj4DWYc/w-d-xo.html but search my channel as I have tones of options to control stepper over WiFi
@@robojax thanks for your reply. But I need to know about homing with limit switch
@@robojax please help me
never head of homing swtich
@@robojax why? Any reason. I need this for upcoming machine
nice.....but can you help me in connecting an lcd display and a hall sensor?
what do you want to display on the LCD screen?
+Robojax rpm
Does the output is a pwm signal?
Arduino can output PWM. you can learn it here th-cam.com/video/oo0v3wWbNIE/w-d-xo.html
Can this sensor be used to detect magnetic field to a person that is being electrocuted?
and also, can this sensor detect a magnetic field without contact?
I have provided the link to the datasheet please see that for full details of the chip.
What will happen, when I connect module to 8 Volts insted of 5Volts?
the components have been calculated for 5V. it might damage the OpAmp chip.
On the module at the end of video you said didn’t work..... I believe the hall sensor is installed backwards on the module.
perhaps you are right.
IC-MH16 Hall encoder, could you send software tutorial
Never heard it before. It looks interesting but I have no tutorial on that.
the output voltage is to low it is 2V and the arduino did not detect it :(
Yes it will. it can detect from 5mV (0.05V) to 5V.
i dont understand your proplem clearly but ypu can use dc - dc boost
