The calibration of conductivity sensor is the key operation to ensure the measurement accuracy. Its core is to correct the measurement deviation of the sensor through the standard solution of known conductivity. The following are common calibration steps, which are suitable for laboratory and industrial online sensors.

The accuracy of rain sensor data is highly dependent on proper installation. This article aims to provide a complete guide from site selection and installation to calibration to ensure your sensor performs optimally.

Air quality sensors are important devices for monitoring pollutants such as PM2.5, PM10, VOCs, and CO₂ in the environment. They are widely used in homes, offices, industrial sites, and smart city systems. Sensor performance may decline due to dust, humidity, chemical contamination, or prolonged use. Therefore, regular maintenance is essential to ensure long-term stable operation and accurate data.

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.

Controlling a Brushless DC (BLDC) motor via RS485 communication provides a highly precise, noise-resistant, and scalable method for industrial automation, robotics, and smart machinery. In this tutorial, we’ll walk you through how to set up a BLDC motor control circuit using RS485 communication, including how to connect and configure a BLDC motor controller with an RS485-to-USB converter for seamless PC-based motor control.

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.

The I/O + SV method can efficiently control the speed and direction of the BLDC motor. This method controls the start and stop and direction of the motor through input signals, and adjusts the speed through variable voltage. In this guide, ATO online store will guide you on how to create a BLDC (brushless DC) motor controller circuit using the input/output (I/O) + speed voltage (SV) control method.

Origin point return control is the control process in the automation system that makes the motion axis return to the preset mechanical origin. It is a standard operation when industrial automation equipment is started or reset. Realizing this function through the cooperation of HMI and PLC is a typical application in industrial automation. Today, ATO Automation will walk you through the complete setup process, from component introduction to system testing.

In industrial automation, communication between a Programmable Logic Controller (PLC) and a Variable Frequency Drive (VFD) is essential for controlling motors and adjusting their speed, torque, and other parameters. Here are the general communication types between a PLC and a VFD.

In many cases, we may need to run three-phase motors on a single-phase power source, especially in residential or small industrial environments without a three-phase power source. Although three-phase motors are more efficient and powerful, simply making some changes to the wiring and adding the correct components can make them suitable for single-phase 220V power supply. In this guide, ATO online store will guide you through the necessary steps to convert a three-phase motor to a single-phase power source for operation.

When converting a three-phase induction motor into a generator, correctly sizing the capacitors is crucial to ensure efficient operation. Capacitors are used to offset the inductive characteristics of the motor, improving its power factor and overall efficiency. If you're wondering, “What size capacitor should I use?”, this guide will walk you through the process of determining the correct capacitor size for your generator conversion project. In this tutorial, ATO industrial automation will explain what ‘capacitor size’ implies and provide you with all necessary formulas and important considerations you would need to figure it out yourself.

Time delay relays play a crucial role in controlling the timing of various electrical processes. But like other electromechanical devices, time relays can become faulty as time goes on and it is vital to check a time delay relay to ensure that it is functioning correctly and maintaining the desired time delay. Now, ATO Automation will introduce you to how to check a time delay relay.

In industrial applications, soft starters are essential for ensuring smooth motor startups. However, there may be instances when a bypass output failure occurs, preventing the motor from functioning properly. This article will guide you on how to rely on an external bypass contactor to continue operating the motor in the event of such a failure, ensuring uninterrupted functionality.

DC-DC boost converter is a power converter used to boost DC voltage to a higher DC voltage. Its working principle is based on the cooperation between energy storage components and switching components (such as transistors), usually controlled by pulse width modulation (PWM) to turn on and off the switches. In this article, we will explore the evaluation tests conducted to assess the performance and reliability of the ATO DC-DC boost converter.

In various applications, you may find the need to power devices that require higher voltages than what your current power supply can provide. A DC-DC boost converter is a device that steps up a lower DC voltage (like 12V) to a higher DC voltage (such as 24V). This type of converter is essential in various applications, especially when powering high-voltage devices from low-voltage sources.
