This is an era where everything is connected. Sensing technology has established a close connection between people and everything. IoT (Internet of Things), this invisible network - physical objects or "things" connected through embedded sensors, software and networks. "Form a network to quickly collect and exchange data, further making people's lives more convenient and their work more efficient.Sensors play a vital role in IoT devices by detecting changes or movements in the environment and collecting data, allowing the device to function accordingly.This article will introduce you to the 10 most commonly used sensors in IoT: temperature sensor, proximity sensor, accelerometer sensor, gyroscope sensor, pressure sensor, liquid level sensor, light sensor, humidity sensor, gas sensor, sound sensor.　　1. Temperature sensorAs the name suggests, temperature sensors measure the temperature of an object or its surroundings and can convert temperature changes into data. Temperature sensors are widely used in environmental temperature monitoring in smart homes, factories, warehouses, etc.2. Proximity sensorThe proximity sensor is called a proximity switch. It detects the proximity of an object through electromagnetic induction. The proximity can indicate the arrival, approach or appearance, departure or disappearance of the object. Proximity sensors are widely used in the Internet of Things, such as common cases in life: smartphones use proximity sensors to detect the proximity of the user's face, and can turn off the screen when the user answers the phone to prevent accidental touching of the face.3. Accelerometer sensorAccelerometer sensors are used to detect the movement or acceleration of an object. It can also be used to detect gravity, and acceleration sensors can be used for smart pedometers and monitoring driving fleets. They can also be used as anti-theft protection, alerting the system when a supposedly stationary object is moved.4. Gyro sensorGyro sensors measure angular rate or velocity, usually defined as measuring speed and rotation about an axis. Gyro sensors are often used in automobiles, such as car navigation and electronic stability control (anti-skid) systems. Other use cases include motion sensing for video games, and camera shake detection systems.5. Pressure sensorPressure sensors are used to measure ambient pressure. Pressure sensors are the most commonly used sensors in industrial practice. They are widely used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military industry, petrochemicals, oil wells, electric power, ships, and machine tools. , pipelines and many other industries. For example, in the automotive industry, it is used to monitor tire pressure and fuel pressure.6. Liquid level sensorLiquid level sensors, divided into contact and non-contact types, are used to detect the level of substances such as liquids, powders and granular materials. Liquid level sensors are often used in manufacturing plants such as water treatment, petroleum, and food plants.7.Light sensorThe light sensor is used to detect the light intensity of the environment. , and convert it into a signal. For example, when a mobile phone is in use, it can detect the intensity of ambient light through an optical sensor, thereby automatically adjusting the brightness of the mobile phone screen. Light sensors also play an important role in the development of driverless car technology.8.Humidity sensorHumidity sensors are used to measure the moisture content of the environment, can monitor soil moisture levels, and are also used in heating, ventilation, and air conditioning (HVAC) systems in industrial and residential areas. Humidity sensors are used in a variety of applications, such as weather stations reporting and predicting weather.9. Gas sensorGas sensors monitor and detect changes in air quality, including the presence of toxic, flammable or harmful gases. Industries using gas sensors include mining, oil and gas, chemical research and manufacturing. Household carbon dioxide detectors, which are very common in life, are also monitored by gas sensors.10. Sound sensorSound sensors are used to detect the sound levels of the environment. It is widely used in smart homes to detect the presence of intruders and in industry to monitor noise levels.

Inductive sensors use the mutual induction principle of metal conductors and alternating electromagnetic fields. The detection coil located at the front end of the sensor generates a high-frequency magnetic field. When a metal object approaches the magnetic field, eddy currents are generated inside the metal object, causing the magnetic field energy to attenuate. When the metal object continues to approach the sensing surface of the sensor, the energy is absorbed and attenuated. When the attenuation reaches At a certain level, the sensor switch is triggered to output a signal, thereby achieving the purpose of non-contact detection.

The sensing surface of the capacitive sensor consists of two coaxial metal electrodes, which form a capacitor and are connected in series in the RC oscillation circuit. When the power is turned on, the RC oscillator does not oscillate. When a target approaches the sensor surface, the capacitance increases and the oscillator starts to oscillate. It is converted into a switch signal through the processing of the downstream circuit, thereby achieving the purpose of detecting the presence or absence of objects. Capacitive sensors can detect metal objects as well as non-metallic objects. For metal objects, they can obtain a suitable large operating distance. For non-metallic objects, the operating distance depends on the dielectric constant of the material. The greater the dielectric constant of the material, the greater the operating distance. The greater the action distance.

As a modern industrial automation equipment, safety light curtains and gratings have attracted more and more attention. As a safety device to prevent robots from accidentally injuring people, safety light curtains are widely used in many production lines and manufacturing industries.What is the working principle of safety light curtain grating? Very simple, the working principle of safety light curtain grating is to detect the position and size of an object through the light reflection between two gratings, thereby determining whether it is an obstacle or a human body. When a human body or other obstacles are detected, the machine will automatically stop running to ensure the safety of the production line and workers.What aspects should be paid attention to when using safety light curtain grating? First, ensure that the installation position of the grating is correct, so that the position and size of the object can be accurately detected and false alarms can be avoided. Secondly, clean and maintain the grille regularly to ensure its normal operation. Finally, during installation and use, you need to pay attention to waterproofing, dustproofing and other issues to extend the service life of the grating as much as possible.What should you pay attention to when using safety light curtains and gratings? First of all, we need to understand the working principle of safety light curtains and gratings. Only by understanding how it works can we better understand how to use it. Secondly, we need to pay attention to the installation location and regular maintenance of the safety light curtain grating to ensure its normal operation. Finally, we need to pay attention to waterproofing, dustproofing and other issues to extend the service life of the grating as much as possible.Safety light curtain grating is a very important industrial safety equipment and has been widely used in modern automated production. Only by correctly using and maintaining safety light curtains can we ensure the safety of machines and workers, and further improve production efficiency and quality. I hope that through the introduction of this article, everyone can better understand the working principle and use of safety light curtain gratings and contribute to the development of industrial automation.
