IoT

IoT stands for Internet of Things, which refers to the network of physical devices embedded with sensors, software, and other technologies that enable them to connect and exchange data over the internet.

Introduction of the 5″ CrowPanel ESP32 Display, featuring a capacitive touchscreen and a resolution of 800×480. As its main control processor, it uses the ESP32-S3-WROOM-1-N4R8 module. This is a dual-core 32-bit LX6 microprocessor with integrated wireless capabilities, supporting both Wi-Fi and Bluetooth. It runs at a main frequency of up to 240 MHz, delivering powerful performance suitable for IoT applications.

Is there an easy way to freely connect several music sources and their multiple receivers at home? Yes! Even if entire environment should be integrated with a COAXIAL-SPDIF switch for the audiophile sound quality? Sure, recently I built the switch that can do that. But now it's time for the main question, is there the easiest and most intuitive way in the world to manage required connecions? To allow anyone seeing it for the first time to control it without any learning? Of course, now there is! All I needed to breathe a new life into my music center is the HMI panel from Elecrow.

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.
