ESP32 WebSocket Real-Time Control Kit: Build a Bi-Directional IoT Dashboard

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

This kit takes you from wiring a breadboard to running a live dashboard where DHT22 temperature and HC-SR04 distance readings refresh every 100 milliseconds — and a button click from your browser instantly toggles a relay. Designed for engineering students and hackathon participants, it demystifies full-duplex communication between an ESP32 server and a web client, exactly the architecture used in industrial monitoring and smart home gateways.

What You'll Build

You will assemble an ESP32 WebSocket server that streams DHT22 humidity/temperature and HC-SR04 ultrasonic distance data in real time to a custom HTML dashboard you code yourself. A bi-directional control layer lets you click an on-screen button to activate the 5V relay or toggle an onboard LED, while the OLED displays local readings. You will walk away with a fully documented project that can serve as an IoT lab prototype or a Smart India Hackathon entry.

What You'll Learn

• Write and deploy ESP32 Arduino code that establishes a WebSocket server capable of handling multiple simultaneous clients.
• Parse and display DHT22 humidity/temperature and HC-SR04 ultrasonic distance data on a dynamic web dashboard.
• Implement bi-directional communication: sending GPIO commands from the browser to toggle a relay or LED.
• Debug real-time network latency and optimize refresh rates for sub‑second updates across local Wi‑Fi.
