This sensor reads QR codes!
This tiny sensor from "Useful Sensors" reads QR codes... or it's supposed to. In practice this I2C sensor is just very finnicky, it's hard to get it to read consistently, most likely due to the low resolution camera which it uses to gather image data.
There may be some very specific uses for this device in your arduino or raspberry pi project, but it feels a bit too rough around the edges for me.
