High-precision digital display counter

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.

Eduponics Mini: ESP32-powered smart agriculture IoT kit with user-customizable mobile app

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.

GoWired Multiprotocol Gateway: The versatile hub for all wired communications

The GoWired Multi-Protocol Gateway is an evolution of one of our previous development boards, the GetWired Ethernet Gateway, with more power, more features, more functionality and a better solution for wired automation systems. It features a powerful ARM M0+ microcontroller with 8x the ROM and 16x the RAM memory. We doubled the RS485 transceiver to be able to use two different communication protocols simultaneously (MySensors, MODBUS, etc.) and added a CAN transceiver as it is also widely used in home automation. USB obviously has to be included as well. To ensure reliable Ethernet communication, we use the market-leading Wiznet W5500 chip. The microcontroller internal memory can be expanded via SD card, for example. G. Used to collect debugging information. The GoWired multi-protocol gateway also features improved power circuitry and can now handle a voltage range of 7-26 VDC. Onboard current and power monitors can periodically share power-related data, as well as other information about device status. For example, an e-ink screen can be used to display this information. All of this is designed with reliability and safety in mind, especially in terms of power supply (ESD, overcurrent, overvoltage, reverse polarity protection) and EMC and EMI precautions. The device is housed in a compact four-slot DIN rail enclosure.
