This kit turns an ordinary doorway into a live counting system using an invisible infrared beam. When someone or something crosses the beam, the ESP32-S3 increments a counter, updates a crisp OLED display, and pushes the latest value to a browser dashboard over WiFi-giving you real-time monitoring from any device on the same network. Perfect for school labs, home aquaponics setups, or Smart India Hackathon prototypes.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Build\u003c\/h2\u003e\n\u003cp\u003eYou'll assemble a complete entry counter that mounts across a door frame. An IR LED emits a beam toward a photodiode; when interrupted, the LM393 comparator sends a clean pulse to the ESP32-S3. The microcontroller displays the count locally and hosts a lightweight web page you can check from a laptop or phone. In under three hours, you'll have a functional IoT monitoring tool ready to deploy in your aquaponics system.\u003c\/p\u003e\n\n\u003ch2\u003eWhat You'll Learn\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eBuild a stable IR break-beam sensor circuit using an LED, photodiode, and voltage comparator\u003c\/li\u003e\n  \u003cli\u003eProgram an ESP32-S3 to handle GPIO interrupts and maintain a reliable count\u003c\/li\u003e\n  \u003cli\u003eCreate a built-in web server that refreshes live sensor data on a browser dashboard\u003c\/li\u003e\n  \u003cli\u003eIntegrate an OLED screen for local readout and troubleshoot signal noise with decoupling capacitors\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eKit Contents\u003c\/h2\u003e\n\u003ctable\u003e\n  \u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eComponent\u003c\/th\u003e\n\u003cth\u003eQuantity\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n  \u003ctbody\u003e\n    \u003ctr\u003e\n\u003ctd\u003eESP32-S3 Dev Board\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eIR LED 940nm\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eIR Photodiode\u003c\/td\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003eLM393 Comparator\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e0.96in OLED\u003c\/td\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e220?
