Anyway played with infrared temperature modules?

@foone i think this is power+- and JFET+- but not sure
@whitequark @foone I wonder. Could you connect it to something like a HX711? Given it’s tuned for bridges.

Anyway played with infrared temperature modules? I have one I tore out of a cheap infrared temperature-gun, but the 4 pins are labeled S+, P+, P-, S-
Every single IR sensor I can find that looks anything like this is I²C, which this clearly isn't. Anyone have a datasheet for anything like this?
@foone 4-wire RS-485?

@foone got a bag of wacky assorted ones like this at surplus, some of them are built like this

@petrillic @foone no (the "crudely" part is there for good reason)

@petrillic @foone but it should have a logic level compatible output i think

@foone thats an analog PIR sensor, it's sort of like a whetstone bridge but made out of photodiodes (to crudely simplify)
@whitequark thanks!

which also doesn't match the pinout of these when you get them in module form, since all of those I've seen go VCC,GND,SDA,SCL

I was gonna say that "the reverse is weird, because they labeled it different: +d and -d instead of +p and -p!
then I realized I'm an idiot who needs her caffeine

who thought it was a good idea for the english language to contain letters that look like other letters when rotated or mirrored? that's clearly a bug to be fixed

@foone sorry, Bob was having a bad day. I hope you understand.

@0 amusingly catgirl detection IS part of what I'm doing with this project!

@foone this made me laugh a lot

@foone let me warn you about the Shavian alphabet then

@chordtoll @foone looks compatible with the info given by Alice.

@whitequark I just learned about Whetstone bridges from curiousmarc: https://youtu.be/0GpT4YlAeTo?is=h5OGlJkzcmyrk2xk
Fascinating stuff.

this looks like a close match, I'm not sure what variant of the family you might have
