Node-RED Dashboard Builder Kit with Raspberry Pi Zero + DHT22
Build a 5-Node IoT Dashboard with Node-RED on Raspberry Pi Zero
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn your Raspberry Pi Zero W into a live data visualization hub that monitors temperature and humidity from five different locations simultaneously. This kit walks you through setting up Node-RED on the Pi, flashing firmware onto five ESP8266 NodeMCU boards, connecting DHT22 sensors, and piping real-time readings into a web dashboard with gauges, charts, and text widgets. It is a complete stack for anyone fascinated by IoT data pipelines, tailor-made to demonstrate how distributed sensor networks work without drowning in complex networking code.
What You'll Build
You will assemble five wireless sensor nodes, each sending environmental readings to a central Raspberry Pi Zero W running Node-RED. The final dashboard—accessible on any device connected to the same Wi‑Fi—displays live temperature and humidity gauges, historical line charts, and numeric indicators that update every few seconds. By the end, you will have a fully functional multi-room climate monitoring system that showcases the core principles of modern IoT architecture.
What You'll Learn
- Install and configure Node-RED on a headless Raspberry Pi Zero W
- Flash ESP8266 boards with MQTT client firmware and connect them to a local broker
- Wire DHT22 sensors with proper pull‑up resistors and read calibrated values
- Design dashboard flows with gauges, charts, and real‑time text outputs

Who This Kit Is For
This intermediate kit is designed for CBSE Class 11–12 students pursuing Computer Science or Electronics, B.Tech ECE/EEE undergraduates tackling minor projects, and participants in events like Smart India Hackathon. It also fits seamlessly into ATL Tinkering Labs and IoT clubs at IIT, NIT, VIT, or BITS campuses where students need a reliable, end‑to‑end sensor dashboard without hunting for compatible components and firmware versions.
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 companion trained on this kit. If you need a human hand, send a WhatsApp message to our support team and we will walk you through the issue within hours.
Can I view the dashboard on my phone while it runs on the Pi?
Yes. Once Node-RED starts, the dashboard is served as a responsive web page. Connect any phone, tablet, or laptop on the same Wi‑Fi network and open the Pi's IP address to see live gauges and charts.
Do I need to know Python or JavaScript to complete this project?
No. Node-RED uses a visual drag‑and‑drop interface, and the ESP8266 nodes come with pre‑written firmware that you simply flash. Basic file editing is enough; the AI companion explains every step.
Can I add more sensors or swap the DHT22 for another type later?
Absolutely. Node-RED has a huge library of nodes for different sensors and actuators. Once you have the MQTT‑based architecture running, adding extra nodes or changing sensor types is a matter of dragging new blocks in the flow editor.
Pi Zero W runs Node-RED. Five ESP8266 sensor nodes feed live gauges, charts and text on web dashboard.
