In <a href=\"https:\/\/www.linkedin.com\/in\/ronibandini\/\" target=\"_blank\" rel=\"noreferrer noopener\">Roni Bandini<\/a>&#8216;s situation, he encountered an issue with a traditional wired doorbell that consistently failed to function correctly. On occasion, it remained completely silent, and even when it did chime, its sound could not reach certain areas within my home. This predicament prompted Roni to contemplate a comprehensive solution: he conceived the idea of crafting a bespoke doorbell system using an ESP32, a push button, Wi-Fi notifications, and two or possibly three buzzers or speakers to address these shortcomings.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img decoding=\"async\" width=\"416\" height=\"555\" src=\"https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2023\/09\/\u4f01\u4e1a\u5fae\u4fe1\u622a\u56fe_16952768523388.png\" alt=\"\" class=\"wp-image-85370\" srcset=\"https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2023\/09\/\u4f01\u4e1a\u5fae\u4fe1\u622a\u56fe_16952768523388.png 416w, https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2023\/09\/\u4f01\u4e1a\u5fae\u4fe1\u622a\u56fe_16952768523388-225x300.png 225w\" sizes=\"(max-width: 416px) 100vw, 416px\" \/><\/figure><\/div>\n\n\n<h2 class=\"wp-block-heading\">The Solution<\/h2>\n\n\n\n<p>Roni decided to address the issue by creating a custom-made doorbell system, utilizing an ESP32, a push button, WiFi alerts, and a pair of buzzers or speakers.<\/p>\n\n\n\n<p>As he pondered the project further, he realized he could enhance its functionality by implementing facial recognition technology to capture visitors&#8217; images, eliminating the need for relying solely on their voices. This innovation even made the push button redundant, thanks to the capabilities of Machine Learning in identifying faces at the door.<\/p>\n\n\n\n<p>Roni found the XIAO ESP32S3 is a compact yet fully-equipped board and ideally suited for this task.

Edge Impulse offers a powerful algorithm called FOMO (Faster Objects, More Objects) designed for precisely this purpose. FOMO is an innovative machine learning algorithm that enables object detection on resource-constrained devices. It empowers you to identify and count objects, pinpoint their locations within an image, and track multiple objects in real-time.<\/p>\n\n\n\n<p>You don&#8217;t necessarily need to capture your own images for this task, as there are numerous face datasets readily available. I recently duplicated an existing Edge Impulse project that already included a dataset of faces, and that proved sufficient. However, if you prefer to use your own images and train a new model, here are the steps to follow:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Collect approximately 400 pictures of faces.<\/li>\n\n\n\n<li>Annotate these images by selecting the facial region and labeling them as &#8220;face.&#8221;<\/li>\n\n\n\n<li>Create an Impulse with image data sized at 96&#215;96 pixels and set up an image processing block.<\/li>\n\n\n\n<li>Implement object detection as a learning block within the Impulse.<\/li>\n\n\n\n<li>Perform 70 training cycles with a learning rate of 0.00015.<\/li>\n\n\n\n<li>Finally, deploy the trained model as an Arduino library and save the resulting Zip file.<\/li>\n<\/ol>\n\n\n\n<p>By following these instructions, you can effectively train a custom model for face detection using your own images.<\/p>\n\n\n\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-2 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"740\" height=\"343\" data-id=\"85405\" src=\"https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2023\/09\/\u4f01\u4e1a\u5fae\u4fe1\u622a\u56fe_16953635075096.png\" alt=\"\" class=\"wp-image-85405\" srcset=\"https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2023\/09\/\u4f01\u4e1a\u5fae\u4fe1\u622a\u56fe_16953635075096.png 740w, https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2023\/09\/\u4f01\u4e1a\u5fae\u4fe1\u622a\u56fe_16953635075096-300x139.png 300w\" sizes=\"(max-width: 740px) 100vw, 740px\" \/><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"740\" height=\"354\" data-id=\"85406\" src=\"https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2023\/09\/\u4f01\u4e1a\u5fae\u4fe1\u622a\u56fe_16953635121697.png\" alt=\"\" class=\"wp-image-85406\" srcset=\"https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2023\/09\/\u4f01\u4e1a\u5fae\u4fe1\u622a\u56fe_16953635121697.png 740w, https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2023\/09\/\u4f01\u4e1a\u5fae\u4fe1\u622a\u56fe_16953635121697-300x144.png 300w\" sizes=\"(max-width: 740px) 100vw, 740px\" \/><\/figure>\n<\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Software settings<\/h3>\n\n\n\n<p>Enter your Wi-Fi credentials<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>#define WIFI_SSID \"\"<br>#define WIFI_PASSWORD \"\"<\/code><\/pre>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Go to Telegram App, search botfather, send \/start send \/newbot<\/li>\n\n\n\n<li>Go to t.me\/sandoombot and get your token<\/li>\n\n\n\n<li>Search idBot in Telegram App<\/li>\n\n\n\n<li>Send \/getId<\/li>\n\n\n\n<li>Send a message to the bot created searching by link<\/li>\n\n\n\n<li>Create a Group and add the bot<\/li>\n\n\n\n<li>Load https:\/\/api.telegram.org\/botXXXXXXX:YYYYYYY\/getUpdates<\/li>\n\n\n\n<li>Extract the ID, like id: -1234567890<\/li>\n\n\n\n<li>Enter Token and ID in these settings<\/li>\n\n\n\n<li>Upload the ino to the Xiao ESP32S3 Sense board.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">The Conclusion<\/h2>\n\n\n\n<p>In summary, the XIAO ESP32S3 Sense device captures images, runs them through a facial detection model, and takes action when a face is found. If it detects a face, it lights up an LED, saves the image, and sends a notification to a family Telegram group.<\/p>\n\n\n\n<p>These tasks may sound complex, but they were relatively easy to implement. This small device, with the help of Machine Learning, not only serves as a doorbell but also offers extra features.<\/p>\n\n\n\n<p>While it doesn&#8217;t include a traditional doorbell sound yet, you can easily add one locally or remotely. You can also improve it by counting people at the door, recognizing friends, and playing a message for visitors.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"250\" height=\"555\" src=\"https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2023\/09\/\u4f01\u4e1a\u5fae\u4fe1\u622a\u56fe_16953645183238.png\" alt=\"\" class=\"wp-image-85409\" srcset=\"https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2023\/09\/\u4f01\u4e1a\u5fae\u4fe1\u622a\u56fe_16953645183238.png 250w, https:\/\/www.seeedstudio.com\/blog\/wp-content\/uploads\/2023\/09\/\u4f01\u4e1a\u5fae\u4fe1\u622a\u56fe_16953645183238-135x300.png 135w\" sizes=\"(max-width: 250px) 100vw, 250px\" \/><\/figure><\/div>\n\n\n<h2 class=\"wp-block-heading\">More Information<\/h2>\n\n\n\n<p><strong>Learn More Project Details on<\/strong>&nbsp;<strong>Hackster:<\/strong>&nbsp;<a href=\"https:\/\/www.hackster.io\/roni-bandini\/machine-learning-doorbell-with-xiao-esp32s3-sense-aa08d0\" target=\"_blank\" rel=\"noreferrer noopener\">Machine Learning doorbell with XIAO ESP32S3 Sense<\/a><\/p>\n\n\n\n<p><a href=\"https:\/\/www.seeedstudio.com\/xiao-series-page\" target=\"_blank\" rel=\"noreferrer noopener\">Seeed Studio XIAO Series<\/a><\/p>\n\n\n\n<p><em>Please feel free to reach out to\u00a0<strong>maker.team@seeed.cc<\/strong>\u00a0for any inquiries or if you\u2019d like to engage in further project discussions.
