Temperature & Humidity Monitor Kit

Overview

This DIY project builds a temperature and humidity monitor. An Arduino Nano reads a DHT11 sensor and shows live values on a 0.96 inch OLED display.

How It Works

1. The DHT11 sensor measures air temperature and relative humidity.
2. The Arduino Nano reads the values through a single data pin.
3. The readings are shown live on the OLED display and refresh every few seconds.

You Will Also Need

A USB-A to USB-C cable to connect the Arduino Nano C-Type to your computer and upload code — not included in this kit.

Applications

• Room monitoring - keep an eye on comfort at home or in the office
• Greenhouses and storage - track conditions for plants or equipment
• Sensor learning - a classic first project with a digital sensor

FAQ

Do I need coding experience? No prior experience is required - this kit is built around one specific project, and the full code is freely available. See the build guide above.

What tools do I need beyond what's included? A computer with the free Arduino IDE (or ESP8266 board support, where applicable) installed to upload the code. No soldering is required for this build. You'll also need a USB-A to USB-C cable to connect the board — not included.

Can I reuse the parts afterward? Yes - every component in this kit is a standard, reusable part you can use in future projects, not a single-use kit.
