Trying to find an obscure sensor

Oldbitcollector (Jeff) · 2021-08-23 08:23

I'm on the hunt for a source of an obscure sensor. It's used in cheap e-cigs.
It detects a slight vacuum (when the user inhales) as the trigger.

Attached is an image of the rear of this sensor.
If someone knows the correct name or better yet a source, I'd really appreciate!
it.

Thanks
Jeff

Hi @"Oldbitcollector (Jeff)", nice to "see" you again!

Isn't it, just the sensor you're looking for?

Capacitive... Does it "sounds" similar to an electret microphone???

Hope it helps

P.S. Yep, they seem to be a byproduct from mike engineering/design:
