🚰 Introduction

Welcome to another video on our Channel, where we discuss integrating consumption data into a smartphone. In today's video, we will focus on the water meter project. We have a water meter that can only be visually read since it lacks any interfaces for integration. However, we have an exciting project using an ESP32 module with a camera that allows us to read and transmit the meter value visually. Stay tuned to learn more about this cool project!

📱 Integrating Consumption Data into a Smartphone

Integrating consumption data into a smartphone is a convenient way to monitor and track resource usage. By connecting devices to your smartphone, you can easily access and analyze the data, providing insights into resource consumption Patterns. In this project, we will focus on integrating a water meter into a smartphone using an ESP32 module with a camera. This will allow us to visually read the meter and transmit the data for further analysis. Now, let's dive into the details of the water meter project!

🌊 Overview of the Water Meter Project

The water meter project aims to provide a solution for visually reading and integrating the data from a water meter into a smartphone. We will be using an ESP32 module with a camera to capture the meter reading visually. The ESP32 module will be installed above the water meter, and a 3D-printed housing will be used to position it properly. The module will illuminate the meter, capture the reading visually, and then transmit the data to the smart home system. This project offers a much cooler alternative to simply adding another meter for integration. Let's move forward and explore the installation and configuration of the necessary software for this project.

🔌 Choosing the ESP32 Module with Camera

To implement the water meter project, we need an ESP32 module with a camera. There are different options available, but for this project, we recommend using a specific module that functions well with the required software. We have provided a link to the module we suggest, and it contains all the necessary components, including a USB 2.0 adapter and an onboard chip. The adapter allows easy connection to your computer for flashing and configuration. Make sure to use a high-quality USB cable for a smooth flashing process. Once you have the module, we can proceed with installing the software.

💻 Installation and Configuration of Software

To start the water meter project, the required software needs to be installed and configured on the ESP32 module. We will use the ESP tool to flash the module with the software. You can find the necessary source code and instructions in the Git repository provided by the developer. Download the source code and the ESP tool, which can be found in the releases section of the repository. Once downloaded, follow the installation instructions to set up the software. Make sure to choose the appropriate port and flash the necessary files, including the bootloader, partitions, and firmware. Take note of the USB cable quality, as low-quality cables may cause issues during the flashing process. Once the flashing is complete, we can proceed to prepare the micro SD card.

📂 Creating the Reference Image

Next, we need to create a reference image that will be used to read the water meter visually. This image will be similar to what we will capture when reading the meter. Initially, the image may appear blurry due to the focus being set to infinity. To adjust the focus, a small point of adhesive needs to be removed from the camera module. This can be done carefully with a sharp object. After removing the adhesive, we can adjust the focus and create a sharp reference image. The software provides guidance on this process, and once we have a clear image, we can move on to positioning the markers on the meter.

🔍 Configuring the Analog Pointers

Configuring the analog pointers involves placing markers on the meter to accurately read the consumption. The software allows us to adjust and position four pointers on the meter. By selecting specific points on the meter and linking them in the software, we can ensure accurate readings. Carefully place the markers on the meter, referring to the reference image and the software. This step is crucial in ensuring precise readings and proper integration into the smart home system. Once the analog pointers are set, we can move forward to finalize the configuration.

✅ Finalizing the Configuration

With the analog pointers configured and the reference image created, we can finalize the configuration. In this step, we select two reference points and assign them to specific values on the meter. This allows the software to accurately read and interpret the consumption data. After setting the reference points, we save the configuration file to the micro SD card. This update ensures that the configuration is applied to the ESP32 module. We can now eject the micro SD card and insert it into the module, ready to test the setup.

🛠️ Troubleshooting and Alternative Solutions

Throughout the water meter project, there might be challenges and issues that arise. One common problem is the compatibility and reliability of the ESP32 modules. While we recommend a specific module, it's important to note that some units may not function as expected. If you encounter such issues, we suggest trying different modules or seeking alternative solutions. Additionally, troubleshooting steps and alternative solutions can be found in the comprehensive documentation provided by the developer. Feel free to explore these resources for further guidance.
