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. 　　

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.

Speed sensor is a common sensor used to measure the speed of an object. It is divided into sensors that measure linear speed and sensors that measure rotational speed. Speed sensors can convert speed information into electrical signals, which can be converted into data through displays or smart devices. They are widely used in automobile and train manufacturing, industrial automation, robotics and medical equipment.

First, let’s briefly understand what a speed sensor is. A speed sensor is a device used to measure the speed of an object and can be widely used in automotive, aerospace and industrial fields. There are many different types and brands of speed sensors available in the domestic market. So, how much does a domestic speed sensor cost? To answer this question, we first need to understand that the price of a speed sensor is affected by many factors. Here are some of the main factors: 1. Brand and quality: Speed sensors of different brands will differ in price. Generally speaking, the price of products of well-known brands will be relatively higher, but their quality and stability may be better. This does not mean that low-priced brands are necessarily of poor quality, but everyone must pay attention when purchasing. 2. Functions and specifications: The functions and specifications of the speed sensor will also affect the price. For example, sensors with certain advanced features, such as tempe
