Best TH-cam explanation for this sensor.
one of the finest tutorial i hv seen thanks a lot ...
hi!
do you know whats the maximum detect-rate (with a raspberry pi and this sensor) if you want to measure the rpm of a motor?
i have a 10k rpm motor and i dont know if the sensor or the pi thinks there is a constant magnetic field above a specific rpm
Hey, nice guide! I was wondering if placing a magnet near the top side of the sensor triggers it?
is there any chance that the magnet displacement detect by the sensor to be used to calculate force?
hi thanks for your video, is it possible to use an arduino nano v3 with the ky 003 magnetic sensor and if it on which pin of the board to connect the signal ? also the voltage should be connect on the 5v?
Hey there, where did you get that mini protoboard on 0:32 ?
Thanks
This can be used to build a wind direction/speed sensor. Thanks for sharing, I learn a lot from your channel.
How???
Everything look easy to do with this channel..
Thomas Alexander True!
First, put the white wire in place. “Ok”
Next, put the red wire in place.
“Ok”
Finally, put the gray wire in place.
*looks at fist-sized spaghetti mass of wires, 7 different colors*
“WTF?!”
Can a hall effect sensor be used to display linear position as in a digital caliper? I want to make a digital measuring display for my mitre saw station's flip stop. I think and inexpensive magnetic encoder (like in cheap Chinese digital calipers) for measuring distance with digital display would be a cool Arduino project with digital display
I want to build a device that tells me when paddles on a machine stop, detecting this will trigger a light to say "im not working". whats my best approach? can you please give me some ideas? thank you
Thanks for such great tutorials !
can you build a magnetic levitation project using hall effect sensor
Such a nice explanation! Thank you!
Is it possible to use 3.3V as supply voltage? kann man den Sensor auch mit 3,3V versorgen?
Can you explain the software code if we want to make a speedometer by the hall effect sensor?
How shall We count the led glow while crossing magnet using hall sensor...I want only count of led glows per second..please advise the code
The good way of doing this is using attachInterrupt(0, isr, CHANGE);
void loop(){
delay(100);
}
void isr(){
here the code you want to run when pin 2 value changes;
}
can hall effect used in analog way? like to detect how close the magnet?
can you measure the range like 0%-100% or is it just two states on/off?
hello, good explanation, but how to get datasheet of such sensor module without which it is difficult to verify its parameters?
can we use it to measure field of 100kHz signal
Can you buld a pov display (persistance of vision)
I had to change one point in your code to work on my arduino UNO R3. My ledPin = 13; would stay on and just dim..
so on how you had it:
pinMode(ledPin, OUTPUT);
it would stay on and just dim or get brighter depending on if I had it set for HIGH or LOW
I switched it to this and it worked so much better with:
pinMode(13, OUTPUT);
the light didnt stay on as with the other..
I hope this helps someone.. Your tutorial was the best one so far.. It did exactly what I was looking for with a slight modification... Using a HE for just turning something off and on..
//////////////////////////////////////////////

int hallSensorPin = 2;
int ledPin = 13;
int state = 0;
void setup() {
pinMode(13, OUTPUT);
pinMode(hallSensorPin, INPUT);
}

state = digitalRead(hallSensorPin);
if (state == LOW) {
digitalWrite(ledPin, HIGH);
}
else {
digitalWrite(ledPin, LOW);
}
}
Such a great tutorial thanks so much!!!
This was first time we could see you (in cell phone screen). I like your channel.
ahahahha yes
Is it able to detect the electro magnetic field?
Can I use this for buttons switches?
can we measure voltage by Hall effect sensor?
is it possible to use a large breadboard?
Can u please tell me how to measure dc current using ARDUINO AND CURRENT SENSOR
Series suggestion.
Bicycle right left flashers using 3 8x8 led modules video one.
Add an lcd or a tft display Hall effect speed sensor and distance on wheel video two.
Add a sensor to automatically turn it on and off, senses activity. Video three.
You could even add a data log or gps video four
HUGE FAN!!!! Thanks
+Mark Greco Thank you, that's a very nice idea. I will try to build it in order to "improve" my nephew's bike!
The sensors i bought don't have that circuit board. is that needed? any other electronics on the board that are needed? I only hav ethe black top part with 3 prongs sticking out. they were like 60 cents each.
you'll only need a 10k resistor (or similar value, above 1k). If you have knowledge about analogic electronics you can use this resistor as a Pull-up resistor (the video uses it as pull-down), connecting the resistor between the pin "gnd" of the sensor and the real gnd, connecting the "signal" pin to 5V and measuring the output of the "gnd" pin, between the pin and the resistor.
I mean can be int state; without giving value 0 ?
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
There's an online calculator. If you want, tell me. I'll try to pass the link.
Nice video and explanation. I'd like to know how hall effect sensors are used to replace potentiometers in joysticks.
Sorry to be so offtopic but does someone know a trick to log back into an Instagram account?
I stupidly forgot the login password. I appreciate any tips you can give me
@Jedidiah Elijah instablaster =)
Does anyone the minimum clearance required between the sensor and the magnet?
what if instead of led ... i will use a buzzer and say, a magnet is put in the lid and if the lid is opened the buzzer will turned off.
Hi sir pls make a video about how to make staircase auto light system. I'm looking for make one. (Using MM5451/ mini pro / and ultrasonic sensor. )
Wind speed: by monitoring distance (the number of revolutions x circumference) over time
as ez as that
Does it detects metal?
Ρε πατριωτη, το θεμα ειναι οτι ο σενσορας φτυνει αναλογικο ρευμα. Δεν ξερω αν ηταν καλυτερο να υπαρχει ολοκληρο το κυκλωμα 1 or 0 για παραπανω ακριβεια.
Excellent video. I have 1 question though. If a stronger magnet is used will this increase the range that the hall sensor activates or do i need a different sensor? Ευχαριστώ.
Yes, the stronger the magnet the bigger the distance it can be detected. Παρακαλώ ;-)
@@Educ8s thank you!
What is the furthest distance that the hall effect sensor will work? Will it detect an electromagnet from a distance away?
It depends on how strong the magnet is. The stronger the magnet the more distance it can be detected.
by using hall effect sensor to measure a rpm of motor
Very nice video.
I think of using hall effect sensors instead of potentiometers. Not sure how, yet.
like how? potentiometers are basically a resistor that you can choose the resistance. A hall effect sensor detects magnetic fields.
How to do for esp8266?
Use the Hall effect sensor for the zero point in a turntable powered by a stepper motor...
How to i make the project which is calculate the how many kilometers is left for reach the destination?
You can use a GPS module
I need to read engine speed this will help
I want to calculate strength of magnetic field . How?
I think this is only output 0 or 1 logic state. To measure of magnetic strength you must use another sensor.
would help if you showed yourself connecting the wires and slowing down when talking. Thank you
siempre me pregunte para que servia ,,

how far can the sensor sense the magnet?
can it sense it within a 10cm radius?
It depends on how strong the magnet is
Hello, it depends of the magnet. There is a online calculator where you can find the magnet type to use with the sensor.
Does anybody know Fernando from Vice City? Since when has he been doing this videos?
hi
could you please make a high frequency (13.56 MHz) three axis magnetic field sensor with arduino.
With this speed you need an extra ADC, capable to samples the signal, almost a 27 MHz, but there is a problem, you will generate a large amount of data, exactly 27 milions of measures any second.
1. Pulse sensor
2. Weight sensor
3. Magnetic hall effect sensor
hi, can you upload a video of sim 900 gprs like server? very good your channel
+rodrigo l Yes I will try to prepare a video on that.
yes I am having trouble to. Even bought another board. Says it working but dosen`t do anything
what tools can be used for a project like this ?
www.koso.com.tw/products-detail.php?id=43
I want to make that tool use arduino
I am very beginner in this case , I hope your help...thanks..
what is State for?
State is creating the variable for digital read. you always create a variable with the value of zero before you use it within the code.
This code could have been written without it yes. i have a video on digital read that might help you.
I AM GOING TO USE IT TO TRIGGER MYPULSE MOTOR COILS !! and then charge batterries with negative energy ! : )
Is his store legit? Seems like a good price
window security ;(
+Hans Müller Yes!
i mean :)
👍❤️
