This project detects hidden cameras using IR light. The photodiode continuously reads the surrounding light and the system first checks the normal light level when it starts. Then it compares new readings with this normal value, and if the value suddenly increases, it means there is a strong reflection which may come from a camera lens. When this happens, the device triggers a buzzer and shows “DETECTED” on the OLED display.

Questions
How big is the Campo PCB?
It measures 65 × 43 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Campo use?
12 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 Campo KiCad files?
From the sohamboyythrdh6/campo repository on GitHub, at the commit this page was made from: the board is pcb/22.kicad_pcb and its schematic pcb/22.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Campo design in my own project?
Its repository states no licence, so its author keeps all rights: ask sohamboyythrdh6 before reusing the design.
