ESP32-S3 Wi-Fi Motion Sensor

I’m building a small device around an ESP32-S3 that must detect motion and push the readings over Wi-Fi. The board will interface only with motion-type sensors (PIR, microwave or similar), no other sensing is required. Once motion is detected the event should be timestamped, packaged and sent through the on-board Wi-Fi interface to a configurable endpoint on my LAN. Key points you will handle • Initialise and read the chosen motion sensor reliably. • Set up stable Wi-Fi connectivity on the ESP32-S3 (station mode, WPA2). • Publish each motion event to an HTTP or MQTT endpoint – I’m open to whichever you can implement fastest. • Keep the firmware lightweight; power-saving features such as deep-sleep after inactivity are a plus. Deliverables 1. Well-commented source code for the ESP32-S3 (ESP-IDF or Arduino-ESP32). 2. Pin-out and wiring diagram for the motion sensor. 3. Build & flash instructions that let me reproduce the firmware from a clean install. 4. A short document or video clip showing the system detecting motion and sending data over Wi-Fi. Acceptance criteria • Motion events appear on my endpoint within one second of detection. • No false triggers during a 4-hour idle test. • Wi-Fi reconnect routine must recover automatically after a router reboot. If you have prior work with ESP32-S3, Wi-Fi stacks or motion sensing, let me know and feel free to suggest improvements before we start.
