STEMinds Eduponics Mini is a smart agriculture and IoT board. With an ESP32 module at its core, Eduponics Mini features an array of built-in sensors - including temperature, humidity, air pressure, ambient light, water and soil moisture sensors - that work together to make smart farming simple and affordable. It supports Wi-Fi and Bluetooth connectivity and consumes very little power, making it ideal for real-world IoT applications. We believe that high-quality industrial IoT and smart agriculture technology should be accessible to everyone, not just those with significant resources and technical expertise. Using MicroPython or the Arduino IDE, you can design your smart garden in no time. We've collected all the documentation you need to guide you step by step into the world of electronics and programming.
In industrial control, it is often necessary to count and measure products to achieve automatic control of equipment. This article introduces a method of making a counter that can set the count value arbitrarily within the display range. Moreover, the current count value, set value, and magnification value will not be lost when power is turned off. It is compatible with a variety of input signals and has a magnification accuracy of up to 5 digits. It is easy to use, stable and reliable, and can be widely used in machine tools, rubber, printing, pharmaceuticals, and cables. , textile, complete sets of control equipment and other industries.
This reference design demonstrates totem pole bridgeless power factor correction (PFC) using the MC56F83783, MC56F81xxx, or MC56F82748 digital signal controller (DSC).
The demo board is designed for isolated 24 V, 5 V, and 3.3 V AC/DC SMPS, delivering up to 5 W to the load. On the input side, a single-phase, 2-phase or 3-phase universal power supply can be connected. The switch-mode converter operates in flyback mode with a maximum frequency of approximately 50 kHz. Built-in overcurrent and short circuit protection. Power consumption is less than 50 mW under no-load conditions. EMI filtering and surge protection using TVS diodes are implemented in this circuit. This application is intended for use as a three-phase low power SMPS and is particularly suitable for three-phase industrial and multi-phase electronic metering SMPS applications.
ANAVI Gas Detector is an open source, easy-to-use, Wi-Fi compatible development board for monitoring air quality and detecting hazardous gases. It supports popular analog MQ gas sensor modules such as MQ-135, MQ-2, MQ-3, etc. In addition, it comes with slots for a mini OLED display and up to three additional I²C sensor modules, including for the precise digital sensor HTU21D to measure temperature and humidity. Air pollution is a very serious problem. Monitoring air quality and detecting toxic gases can improve a person's quality of life. All these features make the ANAVI gas detector suitable for developers, manufacturers, students and open source enthusiasts interested in home automation and environmentally friendly lifestyles.
This provides a fully digital design of LLC resonant converter based on HVP-LLC. The HVP-LLC development board is part of the NXP® High Voltage Platform.
Combined with the HVP-KV46F150 control card, it provides a ready-made software development platform for a 250-watt power supply with an input voltage of 390V DC and an output of 12V/21A.
