IR sensor help

 

evening folks , Ion a quest for a small package IR sensor for a project
I'm working on .

??? Anyone here have a suggestion for one that they have used & are
happy with it ? I'm working with Arduino sized voltages .

thanks

Hi Mike,
Not sure what type of IR sensor your looking for, but I used one of these on my auto oiler system a few years back ...
?
?
It was an H92B4 photo interrupter.? It worked very well both for counting oil drips and with a small metal strip passing between the legs to measure rpm.

Haven't used them yet but I settled on QRE1113 (through hole) for track sensors for a N Scale layout.

I only need to detect at about 3mm max. About 3.6 x 2.9 x 1.7 mm ...

Thanks Julian . I need something that can could revolutions on the spindle on my lathe . I looked for that project in the files this weekend but all I found was like 3 pics . Is it still there & I'm just messed up ?

thanks

I used an Omron rotary encoder to measure spindle location and speed on my lathe. The positioning is useful and enabled me to do an electronic leadscrew (a good project down the line).? It's the thing attached with the orange belt below.? They spin very freely, so you don't need much belt tension and this is one of the poly belts that you cut to length and melt together.

My encoder is 360 pulses per revolution and cost me under $20 on eBay in 2020.? It looks like they might be $30ish now.

A encoder sounds like a much more stable unit than a pair of led's readin? line? or 4 on a spinning shaft . Probably get much less bounce that way .

thanks

I too struggle to find historic stuff on groups IO.

Alex, yes, I did the same.? I had a spare phase on my spindle encoder and used that.? I made a lash-up system with a photo interrupter just to prove it worked and for the benefit of anyone building the system who didn't have an available encoder phase.? I think the photo interrupters were only a couple of quid each and really easy to set up.

??? thats why I couldn't find it , now I remember it was never saved in the file section , just in Messages .

thanks Julian

Alex, would you share your code?

Interesting.? I sent two photos and neither of them showed up on the forum.
 

Hi John
Yes received the photos
Thanks
