This project uses an esp32-cam developer board to build a system that allows the user to control electric devices, request a photo, control flash-LED and get temperature readings via WiFi, interfaced through a telegram bot API.
Further modifications can be added to include PIR Sensor triggered photo capture, LDR controlled lighting, staircase switching for manual over-ride and many more such features.
