Build a High-Accuracy Climate Monitor with SHT31, Arduino Uno, and Live OLED Comparison

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

Most classrooms and hobby setups rely on a DHT22 for temperature and humidity. But when accuracy matters-say for a controlled environment study or a science exhibit-the SHT31 offers �0.3�C precision. This kit lets you build a dual-sensor climate monitor that displays live readings and the difference between them on an OLED screen, teaching you how to benchmark and calibrate sensors.

What You'll Build

You will assemble a compact climate monitor powered by an Arduino Uno that reads the SHT31 and DHT22 simultaneously. A 0.96-inch OLED flashes real-time temperature and humidity from both sensors, along with a rolling comparison of the offset. By the end, you'll have a reliable benchmarking tool that proves how production-grade sensors outperform hobbyist alternatives.

What You'll Learn

• Interface two I2C devices (SHT31 and OLED) via a TCA9548A multiplexer on a single Arduino bus
• Calibrate sensor readings by quantifying offsets between a precision instrument (SHT31) and a common reference (DHT22)
• Design real-time data dashboards on an OLED using Arduino libraries
• Diagnose I2C address conflicts and power stability issues in a mixed-sensor circuit
