Drug test

I was drug tested at work today and the swab and testing unit looked interesting.

The swab and receptacle

The unit it plugged into was a Druglizer LE5 drug tester.

The swab when inserted into the receptical , which then squeezes a predefined amount t of saliva onto the strips to look for the specific antibodies for the drugs they are related to.

The open disposable part of the drug testing unit.

The ic appears to be an i2c eeprom, not sure who from at this stage. pin out aligned with CAT24C32 eeprom


The chip selects are all tied low, the write protect is floating and the SDA and SCL pins are brought out with the power.

Possible datasheet of eeprom
