This afternoon I've received 5 sensors of a certain type¹ I've bought in the weekend.

They were in individual plastic bags (purple), I've put them all in a single plastic bag, and put the bag back in the box they came in.

In the last hour or so I've taken one of them out, connected it to the microcontroller on a breadboard I use for these things, programmed it to use it, it worked. Then I decided to take another microcontroller whose sensor² was broken, and change it with one of these.

So I picked up the soldering iron, all of the accessories, and changed³ the board that connects the microcontroller and the sensor, soldered headers to *another* one of the new sensors, and update the firmware, and everything worked.

And now I wanted to put away the remaining ones in their right place, and I can't find them anymore.

They aren't near in the box, they aren't near the upgraded microcontroller, they aren't in the plastic box where they are supposed to end up

Aaaand thanks everybody, while writing this I looked under the soldering mat (which I had put back into its place) and the sensors were there!

¹ BME280 on a breakout board, but that's not the issue
² SHT20, it had started to give absurd humidity values
³ it's an I2C device. There are 4 pins. *why* is everybody putting them in different combinations??? why can't they settle on something like always putting them in the same order??? (maybe the one used by easyC / StemmaQT, since it's already out there?)
