Live Sensor Data Web Charts Kit — ESP32 Feeds DHT22, BMP280, BH1750 into Your Browser with Zoomable Charts

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

Walk into your room and open a browser tab that streams live temperature, humidity, air pressure, and light intensity — no cloud, no polling, just a direct WebSocket pipe from an ESP32 to your screen. This kit equips you to build that dashboard, complete with zoom and pan controls on every chart. It’s the same approach used in professional monitoring consoles, tuned for a hands-on learning experience.

What You'll Build

You’ll flash an ESP32 with firmware that reads three I2C sensors every second, then pushes the data over WebSocket to a clean HTML page. On that page, Chart.js renders live line graphs for DHT22 temperature and humidity, BMP280 pressure, and BH1750 ambient light — all updating seamlessly. You’ll be able to pinch-to-zoom on mobile or mouse-drag on desktop to inspect spikes, dips, or trends precisely.

What You'll Learn

• Establish a local WebSocket server on ESP32 and stream sensor data without HTTP polling
• Interface three I2C sensors (DHT22, BMP280, BH1750) simultaneously, managing pull-up resistors and addresses
• Create dynamic, interactive line charts with Chart.js, enabling real-time zoom and pan interactions
• Integrate firmware, networking, and front-end code into a standalone IoT monitoring tool that runs entirely on your local network

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This intermediate kit suits CBSE Class 11-12 students tackling a physics or computer science project that demands real-time data acquisition and web visualization. B.Tech ECE/EEE undergraduates at IIT, NIT, VIT, or BITS campuses will find it a ready base for IoT lab assignments. ATL tinkering lab mentors and Smart India Hackathon teams appreciate how the entire stack — sensor to browser — is stripped of complexity so they can focus on innovating.

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.
