Projects include an air quality monitoring system using a PMS7003 sensor, a smart plant moisture monitor with automatic watering potential, a PIR motion sensor for presence detection, a DIY surveillance camera using an OV2640 sensor, and an e-ink personal dashboard. Most projects use either ESPHome with YAML configuration or the Arduino IDE, and leverage the ESP32's built-in Wi-Fi for web server or Home Assistant integration. Total component costs are low, typically under $30 per project. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### What sensor do I need to build an air quality monitor with an ESP32? A PMS7003 digital particle concentration sensor measures PM1.0, PM2.5, and PM10 levels using laser scattering and pairs with a standard ESP32 30-pin board. The sensor costs around $20, and adding an ESP32 board plus a 5V battery brings total project cost to about $30. Configuration is done through ESPHome using a YAML template, with readings displayed on a Home Assistant dashboard. _For hands-on ESP32 sensor builds like this, daily.dev surfaces practical hardware project guides for makers._ ### How do I set up a PIR motion sensor with ESPHome on an ESP32? Declare the PIR sensor in ESPHome's YAML configuration with the device class set to "motion" along with the appropriate GPIO pin. Adding a short delay of a few milliseconds in the YAML configuration reduces false positives from the sensor, making the setup more reliable for presence detection projects. _Makers tuning ESPHome sensor configs can find similar troubleshooting tips on daily.dev._ ### What camera module works with an ESP32 for a DIY surveillance camera? An OV2640 2MP camera sensor paired with an ESP32 board provides basic CCTV functionality at low cost. Configuration uses the CameraWebServer example file in Arduino IDE's Examples tab, requiring only SSID and password changes before uploading. Adding a PIR motion sensor and a light-dependent resistor enables motion-triggered capture and night vision. _Anyone piecing together a budget ESP32 camera build can track similar DIY guides on daily.dev._ ## Similar posts on daily.dev - [11 Interesting ESP32 Microcontroller Projects Beginners Can Try](https://daily.dev/posts/11-interesting-esp32-microcontroller-projects-beginners-can-try-ppanguwyh) · It's Foss · 1 upvotes · 0 comments - [5 ESP32 projects that punch way above their weight](https://daily.dev/posts/5-esp32-projects-that-punch-way-above-their-weight-iayhbilf9) · XDA Developers · 0 upvotes · 0 comments - [4 simple ESP32 projects you can build without any sensors](https://daily.dev/posts/4-simple-esp32-projects-you-can-build-without-any-sensors-pllldxlzb) · XDA Developers · 0 upvotes · 0 comments - [Your first ESP32 project doesn't require coding — it just needs 3 simple tools and one afternoon](https://daily.dev/posts/your-first-esp32-project-doesn-t-require-coding-it-just-needs-3-simple-tools-and-one-afternoon-yovicfcaf) · XDA Developers · 0 upvotes · 0 comments - [DIY ESP32-P4 weather station & air quality monitor connects to LoRa and ESP-NOW sensors, various weather APIs](https://daily.dev/posts/diy-esp32-p4-weather-station-air-quality-monitor-connects-to-lora-and-esp-now-sensors-various-wea-fyniccq3k) · CNX Software · 0 upvotes · 0 comments --- Tags: [#iot](https://daily.dev/tags/iot), [#embedded](https://daily.dev/tags/embedded) [View this post on daily.dev](https://daily.dev/posts/5-esp32-projects-a-total-beginner-can-finish-in-an-afternoon-mo2inkqke) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"5 ESP32 projects a total beginner can finish in an afternoon","url":"https://daily.dev/posts/5-esp32-projects-a-total-beginner-can-finish-in-an-afternoon-mo2inkqke","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/5-esp32-projects-a-total-beginner-can-finish-in-an-afternoon-mo2inkqke"},"datePublished":"2026-07-23T15:00:40.329Z","dateModified":"2026-09-13T19:29:01.294Z","description":"Five beginner-friendly ESP32 projects that can be completed in an afternoon, each with practical real-world utility.
