Laser dust sensors can measure particulate matter (PM) concentrations in the air with high precision and are widely used in environmental monitoring and industrial applications. They are a key component of many modern electronic devices. Which electronic devices are laser dust sensors used in? Air purifiers Laser dust sensors provide continuous, real-time data on PM levels. This information is crucial for air purifiers to adjust fan speed and purification levels, ensuring they effectively remove pollutants. Air conditioners Some high-end air conditioners use dust sensors to manage airflow and filter maintenance, regulating air purification functions. Vacuum cleaners Laser dust sensors in vacuum cleaners detect and quantify dust levels in real time, allowing the cleaner to automatically adjust its cleaning performance. Industrial air quality monitoring In dust-prone industrial environments such as factories, chemical plants, and pharmaceutical factories, laser sensors monitor particula...

With the rapid development of industry, environmental pollution is becoming increasingly serious, especially air pollution, which has become a major hidden danger in people's daily lives. The incidence of respiratory diseases is rising, and severe weather such as haze is frequent, which has significantly increased the public's attention to air quality, and the demand for air monitoring and governance has become more urgent. The demand for purchasing electronic products such as air purifiers is increasing. The PM2.5 laser dust sensor can accurately detect the concentration of tiny particles in the air by using the principle of laser scattering. Therefore, the PM2.5 laser dust sensor has become an important electronic component for environmental monitoring instruments such as air purifiers, air detectors, and PM2.5 detectors. The demand for laser dust sensors in all walks of life is increasing. If you are a manufacturer of related products such as air purifiers, you need to purc...

An amplified airflow sensor is a device used to measure air flow rate. It is a sensor that can amplify weak airflow signals to more accurately measure and monitor airflow parameters. Working principle of the amplified airflow sensor Amplifier sensors are usually composed of sensors, preamplifiers, and post-amplifiers. When working, it first senses weak signals through sensors and converts them into electrical signals. Then, the preamplifier amplifies and filters the electrical signals to eliminate noise and interference. Finally, the post-amplifier further amplifies the signal output by the preamplifier and outputs it to external devices. Application of the amplified airflow sensors It has the characteristics of high precision, high stability, and small size. It can be widely used in HVAC systems, industrial automation, medical respiratory equipment, and other fields.

 The number of channels of a true RMS voltage transducer significantly affects its ability to accurately measure the RMS voltage of a signal. The more channels a true RMS transducer has, the more it can capture a wider range of signal waveforms, and the more it can fully analyze the changes in the signal over time, which may result in more accurate RMS calculation results. The following is an introduction to the classification of true RMS voltage transducers based on the number of channels and their application scenarios. Single-channel (single-phase) true RMS voltage transducer A single-channel true RMS voltage transducer measures the voltage on only one input line, one voltage waveform at a time. It is low-cost due to its simple, compact design, is very easy to install, and is highly compatible. It is mainly used in single-phase AC systems, HVAC systems, and battery management systems The CR4520 supplied by OFweek is a high-precision single-phase  true RMS AC voltage transdu...

Self-powered current transducers are widely used in industrial and energy monitoring because they do not require an external power supply and directly draw power from the conductor being measured. This reduces wiring complexity, installation time, and maintenance costs. The following will tell you some of the key parameters you should pay attention to when purchasing a self-powered current transducer to help you choose the right high-quality current transducer. Key parameters to be clear when purchasing a self-powered current transducer: Determine the type of current to be measured AC current: Choose a model designed for AC systems (50/60Hz). DC current: Look for a model that supports Hall effect sensing for accurate DC measurements. True RMS output: True RMS output is required if the current waveform is non-sinusoidal or distorted. Measurement range Choose a model with the current range that suits your application: Low range: 0–5A Mid range: 0–50A High range: 0–400A or higher Avoid u...

Different from other traditional current sensors, the self-powered current transducer is a device that can measure current and convert it into a proportional electrical signal without an external power supply. It has the characteristics of easy installation and strong environmental adaptability. Power Supply Mode of the Self-Powered Current Transducer Its working power mainly comes from the detection of current in the power transmission line or the power generated by the device under test. The electromagnetic induction or Hall effect principle is used to convert electrical energy into internal electrical energy of the sensor, thereby realizing the self-powered function. Benefits of Self-powered Current Transducer? Easy Installation The self-powered current transducer does not require a wired connection, reduces wiring complexity, and is quick to install. It is particularly suitable for non-contact detection in the transformation of old equipment or complex environments. No Externa...
