WiFi Strength and Speed Meter V2.0 – DIY Guide

Hi Geeks 🙂,This is my first project which I am posting on Instructables So here I am Introducing you the wifi strength and speed meter - a device born out of necessity! 📶⚡️


Have you ever been frustrated by sudden internet dropouts or slow WiFi speeds? I certainly have! That’s why I created this WiFi Strength and Speed Meter v2.0, a compact device that constantly monitors and updates your WiFi signal strength and speed every 3 seconds. With real-time feedback, you can quickly identify weak connections, troubleshoot network issues, and switch to a better network if needed.

Why This Project?

In my previous version, I built a free-form circuit using ESP8266 and a 16x2 LCD display, powered by a micro-USB adapter. While it worked well, I wanted a more compact and battery-powered version with a modern UI and improved aesthetics.

With this upgraded version, I’ve added:

  1. A sleek and modern design
  2. A vibrant display with custom fonts and animations
  3. A 3.7V 500mAh LiPo rechargeable battery for portability
  4. Seeed Studio XIAO ESP32S3, which includes an onboard LiPo charging circuit, enabling direct charging via a Type-C cable

Let’s dive into the step-by-step process of building this WiFi Strength and Speed Meter!

Gathering Components

For this project, you will need:

Electronics

  1. Seeed Studio XIAO ESP32S3
  2. 1.28" Seeed Studio round display (you can use any display)
  3. 3.7V 500mAh LiPo Battery
  4. 3D Printed Enclosure (Optional)

Software & Tools

  1. Arduino IDE (for programming ESP32S3)
  2. TFT_eSPI Library (for display control)
  3. WiFi & HTTPClient Libraries (for fetching network data)

Setting Up the Circuit

  1. Connect the Display to ESP32S3
  2. Display is direct plug and play so no need to connect any external wire from esp32s3 to Display.
  3. Connect the LiPo Battery
  4. The Seeed Studio XIAO ESP32S3 includes a built-in LiPo charging circuit, so simply connect the battery to the provided JST port.
  5. Assemble in a 3D Printed Case (Optional)
  6. If you designed a custom case, fit the components inside securely

Writing the Code

We need to program the ESP32S3 to:

  1. Connect to WiFi
  2. Measure Signal Strength (RSSI in dBm)
  3. Check Internet Connectivity (HTTP Response Code 200 = Success)
  4. Update the Display with Strength & Speed Information

Here you can find the code to convert image(PNG, JPEG, JPG) and GIF into frames that script generate file for you just copy the and create new .h file at the location of your arduino/esp code location and you are good to go.
