I am interested in the EXPLORIR-M-E-100 CO₂ sensor (UART output) shown on your website.
Could you please confirm whether this product is supplied as a bare sensor only, or mounted on a PCB/module with pin headers or terminals, so that it can be directly connected to a microcontroller such as an ESP32 via UART?
If it is only the bare sensor, do you also offer a compatible interface or evaluation board for this model?
Thank you for your help.
