What are the iot sensors

The Internet of Things sensor network can be: 1, according to the sensing principle of classification; 2. According to different types of output control signals; 3, according to the management function classification; 4, according to the actual application of the research field classification. automatic probe station The core of the Internet of Things is the sensor, which can sense and measure various relevant data in the work environment and convert it into a digital signal for subsequent processing and analysis.

First, Internet of Things sensors

The Internet of Things is a technology that connects various physical devices through the network to achieve information exchange and cooperation. At the heart of iot are sensors that can sense and measure various data in the environment and convert it into digital signals for subsequent processing and analysis. The types and functions of iot sensors are very rich, involving temperature, humidity, pressure, light, sound, gas, image and other fields.

Depending on the criteria, iot sensors can be classified differently. private 5g Here are some common ways to categorize:

1. Classification according to the sensing principle

According to the sensing principle, the sensor can be divided into resistance type, capacitance type, inductance type, piezoelectric type, thermoelectric type, photoelectric type, Hall effect type, magnetic sensitive type, etc. Different sensing principles determine the sensitivity and accuracy of the sensor to different physical parameters, as well as its resistance to environmental interference.

2. according to the type of output signal classification

According to the classification of output control signal data types, iot sensor networks can be developed into analog signal system output type and digital signal input and output type. private lte Analog signal output sensors output continuously changing voltage or current signals, which need to be converted into digital signal processing by analog-to-digital converters (ADCs) in order to be recognized by computers or other corporate digital electronic devices. Digital signal output type sensors output discrete-time varying binary signals and can optionally communicate directly with digital devices without the need for additional converters.

3. Classification according to function

According to functional classification, sensors can be divided into active sensors and passive sensors. Active sensors emit energy to objects (such as light, sound, electromagnetic waves, etc.) and detect target information based on reflection or refraction effects. Passive sensors do not transmit energy to the measured object, but detect target information based on the energy emitted by the measured object or the energy affecting the surrounding environment.

4. according to the application field classification

According to the classification of application fields, IOT sensors can be divided into temperature sensors, humidity sensors, pressure sensors, optical sensors, sound sensors, gas sensors, image sensors, etc. Different application fields have different performance requirements and technical difficulties for sensors.

Iot has long been a concern for consumers, who are concerned about the privacy and security issues that come with constant connectivity when using technology such as wearable smartwatches. This consumer concern is common in all types of enterprise iot projects, especially when the end user is the general public.

Enterprise iot solutions can enable companies to improve existing business models and build new connections with customers and partners, but the process may not be easy. The amount of data generated by smart device systems can be extremely large (often referred to as big data). Integrating big data into existing systems and building data analytics to act on it can also be very complex.

When building an iot management system, iot technology security is a very important factor to consider. Nevertheless, for the development of many listed companies in our country, the Internet of Things is still worth a try, and almost all walks of life have their own successful cases of enterprise Internet of Things applications.
