water level automatic control by programmable logic controller

this video show you explains the working principle of the water level sensor and the difference between the floating switch sensor and the water level sensor. How to use KC868-COL + KC868-H32L relay board program to control water tank level by ifttt command automatically.
details about KC868-COL : www.kincony.co...

instead kc868 H32L and Kc868 COL can we use only KC868-A32 ESP32 relay module?

Is there a video about a carbon dioxide sensor and a fan?

[@KinCony]

I think we will take a new video for you to show carbon dioxide raising then open fan.

we have make the new video for co2 auto control fan run and stop. you can see; czcams.com/video/GlKCX0qvSXM/video.html
