Hall Sensor SS495A does not work.

[Spectre]

Hi,

I'm a bit desprate.
First of all, I'm from Germany, so I have to deal with the hall sensor I can get here easily.
Somewhere used the SS495A and got good results.

So i brought one, and tested it quick on a breadboard, before I even made the case for my megadrum kit.
The hall sensor and the neodym magnet worked. I was happy.
Ok, the range did't fit, but I have to adjust it, when it is in a case.

Now I put the megadrum kit, with the positional sensing board in a proper housing.
Before I wanted to solder in the hall sensor in its own housing, I tested its function again with a breadboard.
Nothing happend.

I double checked everything.
I looked up in the data sheet of the SS495, i got the pins right.
I traced the wires from pins on the hall sensor to the pins on the positional sensing board.:

V+ -> pin 40
V- -> GND
Output - > pin 38

It is all as it should be, but it does nothing at all.
Nothing.

I even unplugged the positional sensing board ( the jumper in mind) and tried it, again nothing.
Oh jeah, I even got another SS495, just in case I damaged the first one. The same: nothing.

Has anyone any clue?

Or can anyone recoment a good hihat controller?
Roland, Yamaha, Alesis, the cheap Millenium Stuff?

Thx.

Does voltage on the sensor output vary when you move a magnet around?

[Spectre]

Thx for pointing that out.
In my crazyness I didn't thought of measuring the voltage


First: the supply voltage is 3.46 V.

The output of the SS495A goes from 1.7V to 3.25V when I move the magnet over a distance of about 3cm.

Then make sure you have correctly connected it to HiHat pedal input with good wires and configured MegaDrum properly. When in LowLevel/HiLevel Pedal menu you can see raw values read from the pedal.

I'know that I had similar problems ....no movement.

Even when I turn the magnet and change the high- /low level correctly I got a proper range.

Here a small experience guidline....

@Nepo

I think your postings were the reason why I got an SS495A

@Dmitri and ALL

The the raw values (in min/max menu) say 87, this did not change. Like there is no sensor connected.
But I tested if the pins from the SS495 go to the pins of the pad conector on the positional sensing board.

From SS485 to pad connector:
V+ -> pin 40
V- -> GND
Output - > pin 38

The megadrum just acts like there is no sensor.

But when I first testet it, aber I got the sensor and before I build the housing, It worked a bit.



Or can anyone recommend me a hihad pedal controller, that works fine with the megadrum

[dmitri]

From SS485 to pad connector:
V+ -> pin 40
V- -> GND
Output - > pin 38

Pin 38 (AltIn) is for High Impedance pedal controllers. Did you also set AltIn to Yes in Pedal settings?
Besides, Hall Sensor based pedal controllers are low impedance so you really should connect your controller to pin 39 and leave AltIn as No (default).

Besides, Halss Sensor based pedal controllers are low impedance so you really should connect yours to pin 39 and leave AltIn as No (default).

Thats what I tried, about 2 minutes ago, and now it works.
I now have raw values from 534 to about 1000.
Thank you.

Edit:
But didn't you wrote, that with the positional sensing board, input 38 can handle both, high and low impedance?
