Water turbines convert the kinetic energy of flowing water into mechanical or electrical energy.  Whether used for micro-hydropower systems, small stream generators, or off-grid electricity supply, they offer clean, renewable energy with low operating costs. We offer a variety of water turbines ranging from micro DC generators to high-capacity AC turbines, designed for different flow rates, head heights, and environmental conditions.

This article demonstrates how to control dual stepper motors in both forward and reverse directions using PLC and HMI. It covers the setup, programming, and practical implementation, enabling automatic bidirectional motion for industrial applications. The guide is ideal for engineers and technicians looking to streamline stepper motor control with user-friendly HMI interfaces.

In industrial automation, temperature controllers adjust heating or cooling equipment based on temperature changes through different output methods. They don’t just read temperatures—they actively respond to them. The output method determines how the controller interacts with heaters, coolers, and alarms. Choosing the wrong one can lead to energy waste, unstable temperatures, or even equipment damage. Therefore, precise temperature control is not just about accuracy—it also requires selecting the right controller output method for your specific application. Below, we will explore the seven primary output types of temperature controllers and their impacts on system performance, efficiency, and service life.

Hydropower is a clean, renewable energy source, and while large hydroelectric plants require massive infrastructure, you can actually make a DIY water turbine at home with simple tools and recycled materials. This type of homemade hydropower generator is perfect for students, hobbyists, or anyone who wants to learn how renewable energy works in practice. In this guide, we’ll show you step by step how to build a small water turbine at home.

Shopping for the right DC-DC converter can be overwhelming—especially with so many options available. Whether you're building a smart home device, powering a robotics system, or working on an experimental project, selecting the best DC-DC converter is one of the most important purchasing decisions you'll make. Your choice directly impacts device stability, energy efficiency, and overall performance. This guide will help you understand what to look for when buying a DC-DC converter, so you can shop with confidence and power your projects successfully.

In modern electronic devices, different circuit modules often require different voltages to operate properly. For example, a microprocessor may require a stable 1.2V core voltage, a touchscreen may require a 3.3V drive voltage, and a motor may require 12V or even higher. However, our power supplies—whether batteries, adapters, or solar panels—typically only provide a fixed voltage (such as a 5V USB port or a 12V battery). So, how can we obtain these diverse, stable, and precise voltages from a single power source? The answer is the DC-DC converter.

A speed sensor is an electronic instrument used to detect the speed of an object or device. It converts the rotational speed of the sensor into a corresponding analog output electrical signal, thereby helping to measure the real-time speed of the target object. It is widely used in many industries and fields. For example, the automotive industry uses speed sensors to detect tire movement, the aircraft industry uses them to detect the movement of various aviation equipment, and this technology is also widely used in civilian electronic equipment to measure the rotational speed of materials or objects. To assist you in purchasing the most suitable speed sensor, we provide detailed specifications and pricing information for various types of speed sensors to support your value-driven selection process.

A variable DC power supply is a practical device that can adjust its output voltage based on demand. It's widely used in electronics experiments, lighting control, and regulating electric heating equipment. This article describes a simple method for making a 0-220V adjustable DC power supply, suitable for applications such as adjusting the brightness of an incandescent bulb or the temperature of a soldering iron.
