MiCS-4514 sensor _ power supply
Julien.Moreau 2024-11-13 01:12:40 203 Views1 Replies Hi,
I would like to power the MiCS-4514 sensor with a Raspberry pi. In the doc it is indicated that you can wire it with 3.3V but it is written in all the drawings that it can only be in 5V.
Also it is not explained what to do with the 4th port (EN). If I connect the latest on a GPIO, I assume that I need to specify which one somewhere? However I didn't find where in the provided example scripts
Thanks for your help

Could you check if you write the wrong part number ?
The MICS-4514 can indeed be powered from 3.3~5v and does not have an EN pin
I'm guessing you're using the MICS-5524, which is really only 5V powered, and the EN pin is described in the documentation.
