In this article, you will learn how to build a pocket weather station using an Arduino Nano board. It will be a compact device that you can carry anywhere, right in your pocket; and it will be capable of displaying the live temperature and humidity on the OLED display present on it. This is a great self-care device as you will always know when to take an umbrella out with you, both for the rain and the scorching heat! The device has a built-in rechargeable 160-mAh LiPo battery. It is a really great project for learning and is also fun to make.

Portable Temperature- and Humidity-Measuring Device

Step 1: Gather Components

The first thing to do when beginning with any project is gathering the required components, as shown in Figure 1. The required components for this project are:

  • Arduino Nano with cable
  • DHT11 Temperature Sensor Module
  • 0.96" OLED Display
  • TP4056 Battery Charging Module
  • Small Battery (I used a 160-mAh LiPo battery)
  • Slide Switch
