Plot Real-Time Temperature Graphs on Your PC with Arduino Uno & DHT22 Serial Plotter Kit

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 temperature readings into moving line graphs on your computer screen—no extra components, displays, or complicated software needed. This kit uses Arduino's built-in Serial Plotter tool to transform the DHT22 sensor’s data into a live waveform graph on any Windows, macOS, or Linux machine. It’s the simplest way to see sensor data in action and understand how analog signals translate to digital visualization.

What You'll Build

A complete temperature monitoring system that streams real-time data from the DHT22 sensor to the Arduino IDE's Serial Plotter. You'll see the temperature rise and fall as a continuous line graph updated every second—perfect for observing trends, testing heat sources, or demonstrating data acquisition in school projects. The setup takes under two hours and requires only a USB connection.

What You'll Learn

• How to wire a digital temperature and humidity sensor to Arduino and read precise data
• Using Arduino’s Serial Plotter to graph live sensor values without external software
• Understanding serial communication and baud rates for clean data streams
• Troubleshooting sensor timing and floating input issues in real-world circuits

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This kit is ideal for CBSE Class 11–12 students exploring data visualization in Physics or Computer Science, B.Tech ECE/EEE first-years learning sensor integration, and participants in Smart India Hackathon or ATL Tinkering Labs who need a quick data-logging prototype. With age-appropriate guidance, even students as young as 10 can experience the thrill of seeing real-world measurements turn into live graphs.

Built and Backed by Compoden
