If you want me to explain a certain topic in a video let me know in the comments!
Thanks for watching and see you in the next video 😊

Your videos are well made, and are ideal for beginners. Keep the good work going. Clicking the code link takes to KY 002 example.

Good video, thank you

I have a project I need to design. I want to use this hall sensor system to drive a solenoid when closed and instant return when not. Attached to the solenoid is a weighted plunger. Have any ideas?

[@rongeernaert1208]

Thanks for this lesson, I go to put such a Hall sensor in my selfbild rain gauge, should I put a resistor 200 ohm in this setup ?

[@ud4458]

can the sensor be used to note the rotation position of the magnet , 0 to 360 deg ?

[@prototype8861]

High signal is only 3.5 volts. When magnet is near it takes Signal output to low but the high signal is not 5V but only 3.5V. Not enough for Mach3 to use as home switches.

[@welltronic8216]

Hello, Emre,
yes, the output voltage is only 3.5V. maybe you can amplify the signal to 5V or use a reed sensor.
If you want to switch on the light in a room with a magnet, you can use a reed sensor with a relay or something similar. :)

Every thing i want

[@eugenebrown9803]

just use a 3v to 5v translator its simple

[@kangzero4873]

can we use this module as an Analog input? instead of digital input.

[@FPChris]

Can you detect the range strength like 0% to 100% or just on/off?

[@bluehong2395]

This is a good question which I'm seeking for an answer too

[@williamfraser]

The digital hall sensor simply gives on/off output. An analogue hall sensor has a voltage of around 2.5V on the output pin far from any magnets. The voltage will gradually increase if one polarity is brought near and decrease if the opposite polarity is brought near.

Thanks

I write your code but my serial monitor is not showing any thing although the sensor is working and code is also correct

[@ubairsofi7568]

why you stop making videos.

[@welltronic8216]

I am currently very busy with other projects, work and study. But I'm trying to make more vidoes. The next video will be about infrared sensors. Hope you will like it 😉

[@jamnagarlos2944]

This little gadget. Is dangerous

[@welltronic8216]

😅 Why ?

[@ShinjiCarlos]

Actually your explanation about the Hall effect is not correct. :/
You can address your followers to some Physics text book instead. Halliday or even Friedman could do the job quite nicely. The math is quite simple.
Even your animation at 2:10 is misleading. I'm sorry. Electrons are not attracted by magnetic fields this way. They need to be in motion!
Put simple, a magnetic field pointing perpendicular to the electrons velocity vector will cause them to deflect in a circular motion.
If a magnetic field points perpendicular to the plate where electrons move, they will be deflected into the sidewalls of the sensor, so accumulating in them and therefore generating a voltage difference accross the mentioned walls. If you switch the sense of the magnetic fields, electrons will be deposited in the opposite wall, so causing a switch in the signal of the voltage difference.
