Temperature Gradient Visualiser Kit: Map Vertical Air Temperature with Arduino

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

Mount five DS18B20 probes at measured heights on a sturdy 2-metre pole and map how air temperature changes from ground level upward. The OLED displays a live bar chart of the vertical gradient, revealing microclimate patterns that standard single-sensor projects miss. This kit turns a physics concept into a hands-on investigation suitable for CBSE practicals, B.Tech mini-projects, or Smart India Hackathon prototypes.

What You'll Build

You will assemble a 5-channel temperature datalogger with a DS3231 real-time clock and microSD logging. The Arduino reads each probe in sequence, compensating for any sensor offset, and draws a real-time bar chart on the 0.96-inch OLED. By mounting the probes at fixed heights, you can observe temperature inversions in the morning, cooling rates near the ground, or the effect of shade on different layers — all recorded with timestamps for later analysis.

What You'll Learn

• Calibrating multiple DS18B20 sensors over OneWire bus and addressing each probe uniquely
• Structuring Arduino code for multi-channel data acquisition and interval logging to SD card
• Interpreting environmental gradient data and correlating it with weather science concepts
• Designing a battery-powered field instrument with real-time clock and non-volatile storage

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

If you are a CBSE Class 11-12 student looking for a physics investigatory project on heat transfer, a B.Tech ECE or EEE first-year working on an environmental sensing assignment, or a team at Smart India Hackathon prototyping a smart agriculture device, this kit gives you a ready-to-assemble system with validated components. ATL Tinkering Lab facilitators and IIT/NIT/VIT/BITS mini-project groups can also use it to teach real-world sensor integration without sourcing headaches.
