Gas sensors (SEN471, SEN472, SEN470, SEN466) stop working over time on ESP32-S3

I’m using multiple gas sensors (NO₂ – SEN471, O₃ – SEN472, SO₂ – SEN470, CO – SEN466) with an ESP32-S3.
Each sensor works fine individually, but when I use them together, they work at first and then stop responding after some period of time.
Has anyone experienced this or knows what might cause it?
Thanks!

Hi, it may be caused by insufficient power supply or ESP32 overload after long-term operation.
