The ENS210 is an uncategorised made by Sciosense in a QFN-4-EP(2x2) package with 5 pins. QFN-4-EP(2x2) Temperature and Humidity Sensor ROHS.
PCBKit's library has its KiCad symbol (Sensor_Humidity:ENS210, from KiCad's library) and its footprint (Package_DFN_QFN:AMS_QFN-4-1EP_2x2mm_P0.95mm_EP0.7x1.6mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C2912570). 25 open-source boards in 23 repositories on GitHub use it.

I'm thinking that this repo can be a collection of everything we are up to with code, PCB design, 3D models and also general planning.

The symbol is Sensor_Humidity:ENS210 and the footprint Package_DFN_QFN:AMS_QFN-4-1EP_2x2mm_P0.95mm_EP0.7x1.6mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
QFN-4-EP(2x2), with 5 pins. Its footprint is drawn on this page.
JLCPCB lists it as part C2912570, with 0 in stock; the sellers' links on this page open their listings.
Parts like it in the library: the ENS210A-LQFM by Sciosense. Check their datasheets: a part that fits the footprint may still differ in its ratings.
