Device Marking of HTS221 Sensors

Hello, how can I identify HTS221TR sensor?

We've got some of them with marking H509.

Looks strange.

The device is correctly marked: H stands for HTS221, the following numbers are year (2015) and week of manufacture (09).

Hi @SNats.1 ,

did you just receive samples from a 2015 LOT? Or did you had it stored in your warehouse?

Hello, Eleon.

We've got sensors stored for some time (since '17-'18) as an emergency supply, so now their time has come.
