I enjoyed your clear voice, reasonable pace, and no annoying music. Good for slow learners like myself. :-) I came here via 'Instructables' while looking for a hall effect tachometer with LCD display. Thank you.
Strangest comment I've ever left, but your hands look the same as mine and it felt really weird watching them move around 😅 interested video though, subscribed.
Nice explanation. Thank you. I am using the hall sensor output to read the rpm of 8 pole BLDC motor. I am trying the formula but not getting the relevant reading. May I know how the interrupt and counter function should be used for the same?
I'm glad you like it. There is no capacitor required in the circuit. You only need the pull-up resistor across VCC and output, or pins 1 and 3. You can add an additional 100pF capacitor between VCC and GND but that is not required at all.
Well that explains it as what you have is a Switching Bipolar Sensor. One pole of the magnet turns it on and the other turns it off. You can see the behavior in the datasheet at page 5 on the graph. What is it that you are trying to build? Any specific project?
Many thanks for sharing this. I learn a lot from wonderful people like you. I think this can be used to build a weather station that records wind direction and speed. For wind direction, I think I will be needing 8 hall affect sensors to detect changes in wind from N, NW, W, SW, S, SE, E and NE plus maybe another sensor to record wind speed. Would it be possible to connect all 9 hall sensors to arduino and use interrupts to process the incoming data?
That is a really good idea. However, the Uno has only 2 external interrupts so you'll need have them connected to regular digital pins. Definitely doable 👌

You are welcomed! I'm glad you linked it!
This was a great tutorial. I was wondering if you have used the 3144 for reading analog values. Sort of like a magnetometer.
Thanks! No I haven't! I've only used it as a general on/off switch.
Nice explanation. I’m planning on a Hall effect interrupt for a select fire nerf blaster shot counter
Cool. That sounds like a fun project! Good luck with it!
Could a hall sensor mounted to next to a flywheel close a normally open pneumatic valve?
The hall effect sensor can provide the signal but something else must activate the pneumatic valve depending on how it is controlled.

Hhahhahaahahah well that is for sure a strange comment 😅😅😅 but I guess I would have felt the same. Thanks!
This is very helpful information. Thank you.

Sorry but I'm not familiar with how it should be done for motor control.
Nice video, thanks. Not being a electronics guy, I was wondering if you could tell me where to connect the capacitor. Cheers

Hello, I tried the code with CHANGE, but the diode wont turn off until I come close with other side of the magnet. Could you please help me?
Sure, can you confirm that you have the same sensor?
@@TasteTheCode Unfortunately I use TLE 4935 L (heres datasheet www.gme.cz/data/attachments/dsh.533-442.1.pdf )
