This article will provide a detailed introduction to the operating principles, main types, and application scenarios of rain sensors, providing a deeper understanding of how this technology can aid meteorological observation and water resource management.

Rain sensors are widely used in automotive intelligent driving systems, and automatic wipers have already occupied a certain share in most automotive-related fields. Rain sensors used to control wiper speed and frequency can not only improve comfort but also enhance driving safety.

With the deepening of smart environmental protection construction, the role of air quality sensors has become increasingly important. Based on actual application needs, this guide scientifically analyzes outdoor environmental factors, accurately determines monitoring height ranges, and standardizes installation and operation procedures to help users establish appropriate air quality monitoring points and ensure that each monitoring data accurately reflects the environmental quality status.

With the continuous advancement of industrial automation, electrical control technology is also undergoing continuous development and innovation. As essential components of electrical control, relays and contactors are playing an increasingly crucial role, especially in high-voltage electrical equipment, where safety and stability have a significant impact on production processes. In recent years, controlling 380V AC contactors with 24V DC relays has become a popular solution. This article will delve into the application principles, advantages, and vital role of this technology in modern industry.

In modern electric tricycles, the DC contactor, as a crucial circuit component, plays an indispensable role. It not only controls the start and stop of the motor but also plays a key role in switching the battery current. Improper DC contactor wiring can not only affect the performance of the electric tricycle but can also cause battery damage, control system failures, and even threaten driving safety in serious cases. Therefore, ATO Automation will provide essential and correct wiring methods for every electric tricycle user and maintenance technician.

Controlling a BLDC motor using a combination of RS-485 communication, PWM frequency, and I/O switching offers versatile and precise control over speed and direction. In this tutorial, we'll show you how to wire and configure a hybrid system that leverages all three control modes for smooth, scalable motor operation in automation and smart control systems.

In modern industrial and automation systems, precision motor control is essential. One highly effective method for achieving this is through the use of RS-485 and CAN bus communication protocols. In this guide, we'll walk you through setting up a BLDC (Brushless DC) motor control system using both RS-485 and CAN interfaces to enable accurate, real-time speed and direction control.

Have you ever wondered why some desk lamps can change the brightness of the bulb from dim to bright by just turning the knob? In this article, ATO Online Store will delve into the dimming circuit inside these desk lamps and uncover the technological secrets behind them.

Bearings are essential components in mechanical design and industrial manufacturing. Although they are small in size, they play a key role in transmission systems. Today we are going to talk about two common but very different types of bearings: Deep Groove Ball Bearings and Linear Ball Bearings. Although they both contain "Ball Bearings" in their names, they are very different in structure, function and usage scenarios. Understanding their differences will help engineers and designers make appropriate selections for different projects.

Density meter is an important instrument used to measure the mass per unit volume of a substance. It is widely used in petrochemical, food and beverage, pharmaceutical, metallurgy, material research and other fields. Due to different application scenarios and measurement objects, there are many types of density meters, which can easily confuse people when selecting. ATO will systematically classify density meters from three dimensions: usage scenarios, measurement media and working principles, and illustrate them with typical examples to help everyone quickly understand the characteristics and uses of various types of density meters.

A fire pump is a specialized device used to increase the pressure and flow rate of water in a fire protection system, such as a sprinkler system or standpipe system, to ensure an adequate water supply in the event of a fire. Fire pumps are designed to deliver large quantities of water at high pressures and are often installed in commercial or industrial buildings as well as in high-rise residential buildings.

An absolute encoder is a detector that outputs angular data to an external target within one revolution of the motor. Absolute encoders are typically capable of 360° output in 8 to 16 bits. ATO.com online store offers single-turn absolute encoders and multi-turn absolute rotary encoders for you to choose from, offering 10-bit/12-bit/14-bit rotary encoders. Below is a price list of some of the absolute encoders in our store for your reference.

A desoldering pump, also known as a solder sucker or tin suckers, is a hand or power tool widely used in electronic repair and assembly, mainly for removing excess solder from circuit boards and helping technicians safely remove electronic components. The desoldering pump is commonly used to repair old circuit boards, replace faulty components, reinstall soldered parts, or perform tin removal cleaning of circuit boards, and is one of the indispensable tools for electronic engineers, repairers, and DIY enthusiasts.

In the previous article, we explored how to control a BLDC (Brushless DC) motor using the I/O+SV control method. In this article, we will introduce another efficient approach: I/O+RV control.
