Identify noxious air bubbles lurking in the substrate w/ ultrasonic scans and assess water pollution based on chemical tests simultaneously.

Weather Crow is an ESP32-S3 based weather station featuring an E-paper display that shows current weather conditions and forecasts. This initial release provides a complete solution for monitoring local weather with minimal power consumption through efficient deep sleep cycles. the project is under the MIT license, so you can modify or chage as you want!!

This project is the development of a fully integrated, standalone Voice Assistant built upon the ESP32-C6 microcontroller. It leverages two major cloud AI services—Gemini 2.0 Flash for intelligence and Murf AI for realistic speech generation—to create a seamless, conversational experience for the user.

The DIY Heating Booster helps you get more out of your existing radiator – without modifying your heating system. An ESP32 controls 12V fans mounted underneath the radiator, automatically turning them on when the radiator gets warm to efficiently distribute heat throughout the room. The control logic works standalone with a local temperature sensor, but can also be fully integrated into Home Assistant. Perfect for cold spots, smart upgrades, and energy-saving DIY solutions.

A custom IoT controller that manages street lighting over LoRaWAN and turns each streetlight into a fixed BLE beacon for proximity-based smart city services.

Discover the potential of the 2.8” ESP32 Miner Display by Elecrow: a compact development board that integrates a powerful ESP32 microcontroller with a TFT touchscreen, Wi-Fi, and Bluetooth connectivity. In this project we explore its features, hardware architecture, and development possibilities using the Arduino IDE. The tutorial shows how to configure the board, upload example code, and create graphical interfaces, turning this device into a versatile platform for IoT dashboards, smart home control panels, and embedded HMI applications.

One of the best Chinese produced Energy Monitor ASICs now easier than ever to use

A ready-to-use weather station. Quick setup: flash the prebuilt firmware and start testing in under a minute, no coding required. Open-source and customizable for your own weather-based projects. Firmware and source code available on GitHub.

Turn your CrowPanel 5.79" into a dedicated desktop command center. While ultra-wide displays often live in landscape, flipping this 272×792 panoramic e-paper display vertically unlocks the ultimate low-power, zero-glare dashboard for real-time task management, live crypto/stock tickers, and smart home telemetry. Engineered specifically for makers, this modular 3-piece enclosure features an ergonomic desktop tilt, zero-strain glass bezel clearance, integrated rear cable management, and side port access. Optimized for Bambu Studio to print flat without wasteful supports, this project bridges functional industrial design with open-source ESP32 firmware—bringing clean aesthetics and practical desktop utility to the Elecrow ecosystem.
