Help With 100mV Inputs with B2S

Archiver

I'm trying to take in 13 inputs that average around with a voltage
drop of only 100-200 mV.

Basically these are a bunch of aftermarket car sensors. They all
have one wire that drops to low when the sensor is triggered.
However after hooking up a voltage meter to these sensors..it seems
that they only drop 100mV. Either I'm not doing something correct on
the stamp (I'm brand new at this). Or that drop is too little for
the stamp to detect it.

If anyone has suggestions on this..it would be great!

Thanks.

The stamp cannot recognize a 100mv Drop. However, I suspect there may be a
problem with your measurement technique......

What kind of automotive sensors are you using? MAP sensor? ECT? Knock sensor?
TPS?.....???

Please elaborate on what sensors you are looking at....I work in the
automotive industry for a major vehicle manufacturer R&D center and should be
able to help....

Also, can you paste a link to the sensors you are using?
