ESP32 WebSocket Real Time Dashboard Kit with ESP32 + DHT22
Build a Real-Time Sensor Dashboard with ESP32 WebSocket Kit – Live Temp, Humidity & Distance
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform your desk into a live IoT command centre. This kit lets you build an ESP32‑powered WebSocket server that pushes DHT22 temperature‑humidity and HC‑SR04 ultrasonic distance readings to a browser dashboard every 100 milliseconds. You can even toggle a relay from the dashboard — bidirectional control, pure data magic without page refreshes.
What You'll Build
You'll create a fully functional web dashboard that updates live sensor values and responds to your commands. The ESP32 hosts a lightweight WebSocket server; open the dashboard on any phone or laptop connected to the same network and watch temperature, humidity, and distance values stream in. A relay switches an external device on or off with a button click on the dashboard — a real‑time control loop that works as smoothly as a commercial smart home panel.
What You'll Learn
- Establish a persistent WebSocket connection between an ESP32 server and a browser client for sub‑100ms data pushes.
- Read and calibrate DHT22 and HC‑SR04 sensors, parse their outputs, and format JSON payloads for the frontend.
- Code bidirectional logic — send sensor data to the dashboard and receive relay toggle commands back on the ESP32.
- Design a responsive HTML/CSS dashboard that updates fields in real time without reloading, using JavaScript DOM manipulation.

Who This Kit Is For
This intermediate project fits CBSE Class 11–12 students polishing their computer science or electronics portfolios, B.Tech ECE/EEE sophomores who want to crack IoT internships, and Smart India Hackathon teams building sensor‑network interfaces. ATL Tinkering Lab mentors and IIT/NIT/VIT/BITS makers will find the real‑time WebSocket angle a step beyond basic HTTP polling — exactly the kind of hands‑on depth that stands out in project reviews.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to chat with the AI build companion trained on this exact dashboard project. It can debug your code, suggest wiring fixes, or escalate you to our WhatsApp support team in minutes.
Do I need an internet connection for the dashboard to work?
No. The ESP32 creates its own Wi‑Fi network (or connects to your local router). The dashboard runs entirely on your browser inside that local network — no cloud dependency.
Can I modify the dashboard or add more sensors later?
Absolutely. The source code is fully open and modular. You can integrate additional I2C sensors, change the refresh rate, or style the dashboard with your own CSS after the first build.
Is this kit suitable for a CBSE or engineering project submission?
Yes. The real‑time WebSocket architecture, sensor fusion, and bidirectional control demonstrate concepts well beyond typical Bluetooth or LCD projects. It’s a strong demonstration of IoT fundamentals and embedded web development.
ESP32 WebSocket server pushes DHT22 and HC-SR04 data to browser dashboard every 100ms bidirectionally.
