Questions

How big is the IR Proximity Sensor PCB?

It measures 30.1 × 13.1 mm and has 2 copper layers, 1.6 mm thick.

What parts does the IR Proximity Sensor use?

11 parts, built around the LM358. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the IR Proximity Sensor KiCad files?

From the harshakvp/PCBProjects repository on GitHub, at the commit this page was made from: the board is KiCAD/IR Proximity Sensor/IR Proximity Sensor.kicad_pcb and its schematic KiCAD/IR Proximity Sensor/IR Proximity Sensor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the IR Proximity Sensor design in my own project?

Its repository states no licence, so its author keeps all rights: ask harshakvp before reusing the design.
