While most AI systems rely on powerful processors or cloud computing, **edge computing** brings AI closer to the end user by utilizing the capabilities of modern processors. This project demonstrates edge computing using the **ESP32**, a low-cost, AI-capable device, to digitize your analog meters—whether water, gas, or electricity. With affordable hardware and simple instructions, you can turn any standard meter into a smart device. Let's explore how to make **AI on the Edge** a reality! 🌟 All you need is an [ESP32 board with a supported camera](https://jomjol.github.io/AI-on-the-edge-device-docs/Hardware-Compatibility/) and some practical skills. 🛠️ --- <br> ## Key Features 🚀 - 🔗 **Tensorflow Lite (TFLite) integration** – including an easy-to-use wrapper. - 📸 **Inline image processing** (feature detection, alignment, ROI extraction). - 💡 **Small** and **affordable** device (3 x 4.5 x 2 cm³, less than 10 EUR). - 📷 Integrated camera and illumination. - 🌐 Web interface for administration and control. - 🔄 OTA interface for updating directly via the web interface. - 🏠 Full integration with Home Assistant. - 📊 Support for **Influx DB 1** and **2**. - 📡 **MQTT protocol** support. - 📥 **REST API** available for data access. <br> ## Workflow 🔧 The device captures a photo of your meter at set intervals. It then extracts the Regions of Interest (ROIs) from the image and runs them through artificial intelligence. As a result, you get the digitized value of your meter. There are several options for what to do with that value: - 📤 Send it to a **MQTT broker**. - 📝 Write it to an **InfluxDb**. - 🔗 Provide access via a **REST API**. <p align="center"> <img src="images/idea.jpg" width="600"> </p> --- <br> ## Impressions 📷 + ### AI-on-the-edge-device on a Water Meter 💧 <p align="center"> <img src="images/watermeter_all.jpg" width="200"><img src="images/main.jpg" width="200"><img src="images/size.png" width="200"> </p> + ### Web Interface (Water Meter) 💻 <p align="center"> <img src="images/watermeter.jpg" width="600"> </p> + ### AI-on-the-edge-device on an Electrical Power Meter ⚡ <p align="center"> <img src="images/powermeter.jpg" width="600"> </p> --- <br> ## Setup 🛠️ There is growing [documentation](https://jomjol.github.io/AI-on-the-edge-device-docs/) which provides you with a lot of information. Head there to get started, set it up, and configure it. There are also articles in the German Heise magazine "make:" about the setup and technical background (behind a paywall): [DIY - Setup](https://www.heise.de/select/make/2021/2/2103513300897420296) 📰 A lot of people have created useful YouTube videos that might help you get started: - 🎥 [youtube.com/watch?v=HKBofb1cnNc](https://www.youtube.com/watch?v=HKBofb1cnNc) - 🎥 [youtube.com/watch?v=yyf0ORNLCk4](https://www.youtube.com/watch?v=yyf0ORNLCk4) - 🎥 [youtube.com/watch?v=XxmTubGek6M](https://www.youtube.com/watch?v=XxmTubGek6M) - 🎥 [youtube.com/watch?v=mDIJEyElkAU](https://www.youtube.com/watch?v=mDIJEyElkAU) - 🎥 [youtube.com/watch?v=SssiPkyKVVs](https://www.youtube.com/watch?v=SssiPkyKVVs) - 🎥 [youtube.com/watch?v=MAHE_QyHZFQ](https://www.youtube.com/watch?v=MAHE_QyHZFQ) - 🎥 [youtube.com/watch?v=Uap_6bwtILQ](https://www.youtube.com/watch?v=Uap_6bwtILQ) For further background information, head to: - [Neural Networks](https://www.heise.de/select/make/2021/6/2126410443385102621) - [Training Neural Networks](https://www.heise.de/select/make/2022/1/2134114065999161585) - [Programming on the ESP32](https://www.heise.de/select/make/2022/2/2204010051597422030) --- <br> ## Download 🔽 The latest available version can be found on the [Releases page](https://github.com/jomjol/AI-on-the-edge-device/releases). --- <br> ## Flashing the ESP32 💾 Initially, you will have to flash the ESP32 via a USB connection. Later updates are possible directly over the air (OTA using Wi-Fi). There are different ways to flash your ESP32: - The preferred way is the [Web Installer and Console](https://jomjol.github.io/AI-on-the-edge-device/index.html), a browser-based tool to flash the ESP32 and extract the log over USB:  - Flash Tool from Espressif - ESPtool (command-line tool) See the [documentation](https://jomjol.github.io/AI-on-the-edge-device-docs/Installation/) for more information. --- <br> ## Flashing the SD Card 💾 The SD card can be set up automatically after the firmware is installed. See the [documentation](https://jomjol.github.io/AI-on-the-edge-device-docs/Installation/#remote-setup-using-the-built-in-access-point) for details. For this to work, the SD card must be FAT formatted (which is the default on a new SD card). Alternatively, the SD card can still be set up manually. See the [documentation](https://jomjol.github.io/AI-on-the-edge-device-docs/Installation/#3-sd-card) for details. --- <br> ## Casing 🛠️ Various 3D-printable housings can be found here: - 💧 [Water Meter](https://www.thingiverse.com/thing:4573481) - ⚡ [Power Meter](https://www.thingiverse.com/thing:5028229) - 🔥 [Gas Meter](https://www.thingiverse.com/thing:5224101) - 📷 [ESP32-cam housing only](https://www.thingiverse.com/thing:4571627) - 📡 [Top cover and Antenna Holder](https://www.printables.com/model/452139-cover-for-esp32-cam-water-meter) --- <br> ## Donate ☕ If you'd like to support the developer with a cup of coffee, you can do so via [PayPal](https://www.paypal.com/donate?hosted_button_id=8TRSVYNYKDSWL). <p align="center"> <a href="https://www.paypal.com/donate?hosted_button_id=8TRSVYNYKDSWL"><img border="0" src="images/paypal.png" width="200px" target="_blank"></a> </p> --- <br> ## Support 💬 If you have any technical problems, please search the [discussions](https://github.com/jomjol/AI-on-the-edge-device/discussions).
