Sensors - the key components behind automation and control in modern industrial systems. In the increasingly complex environment of industry and automation, sensors play a vital role in collecting data, measuring technical parameters and helping to ensure the efficient operation of equipment and processes submit.
We'll begin this journey by exploring the basics of sensors, as well as how they work to convert information from their surroundings into electrical signals. At the same time, we will learn about the widespread application of sensors in the field of Automation Equipment and their important contributions to technological and manufacturing advancement.
Let's explore more deeply with Amazen about common sensor lines in today's production life!
1. What is a sensor? Sensor classification - Common types of sensors today
Sensors are devices capable of converting a form of energy from the surrounding environment into an electrical signal, providing information about parameters such as temperature, pressure, humidity, light, or other variables. other. They are commonly used for measurement, monitoring, and control in many fields, including industrial automation, medical, automotive, and many other applications.
Sensors are classified based on many different criteria, including:
-
According to the operating principle
- Electrical sensors: Based on electrical phenomena such as Hall effect, capacitive effect, thermoelectric effect,...
Optical sensors: Based on optical phenomena such as photoelectric effect, photoconductivity effect, photoluminescence effect,...
Magnetic sensor: Based on magnetic phenomena such as Hall effect, electromagnetic effect,...
Thermal sensor: Based on thermal phenomena such as thermoelectric effect, thermal resistance effect,...
Force sensor: Based on force phenomena such as electric piezo effect, magnetoelectric effect,...
Chemical sensors: Based on chemical reactions to measure the concentration and composition of chemicals.
Biosensor: Based on biological phenomena to measure biological parameters such as blood pressure, heart rate,...
-
According to the output signal
- Analog sensor: The output of the sensor is a continuous signal.
Digital sensor: The output of the sensor is a discrete signal.
-
According to the operating environment
- Sensor in atmospheric environment: Sensor operates in atmospheric environment.
Sensor in water environment: Sensor operates in water environment.
Sensor in solid medium: Sensor operates in solid medium.
Below are some common types of sensors today:
- Temperature sensor: Measures the temperature of the surrounding environment and converts it into an electrical signal. Common types include thermocouples, thermistors, and infrared sensors.
Pressure sensor: Measures the pressure of a liquid or gas and converts it into an electrical signal. Piezoelectric sensors and steam bridge pressure sensors are some examples.
Humidity sensor: Measures the humidity of the environment and converts it into an electrical signal. Humidity sensors can use capacitive, resistive, or electronic technology.
Light sensor: Measures light intensity and converts it into an electrical signal. Photodiode sensors and CCD sensors are some common types.
Motion Sensor: Detects object movement and converts it into an electrical signal. Passive infrared (PIR) sensors and ultrasonic sensors are examples.
Accelerometer: Measures acceleration and converts it into an electrical signal. They are commonly used in applications such as measuring speed and direction of motion.
Positioning sensors: Used to determine the location of an object or device. GPS sensors are an example.
Magnetic Sensor (Inductive Sensor): Magnetic sensors are used to detect metallic objects. When a metal object comes into contact with or comes close to the sensor, it creates a change in the current or frequency and sensor size, which in turn is converted into an electrical signal.
Proximity Sensor: Proximity Sensor is designed to detect the presence or location of an object in a specific area without touching the object. Infrared sensors and ultrasonic sensors are often used to meet this need.
Rain Sensor: Rain sensors are often used in automotive systems to automatically turn on lights or activate autopilot when rain is detected. This sensor works by detecting water droplets on the sensor surface, converting this perception into an electrical signal to activate the corresponding systems.
Optical Sensor: Optical sensors use light to detect changes in the surrounding environment. Types of optical sensors include water level sensors, oil level sensors, or liquid level sensors in industrial applications.
2. Structure and operating principles of various types of sensors
Rain sensor
Structure
The rain sensor consists of two parts, the sensor pad and the sensor module. Whenever rain falls on the surface of the sensor plate, the sensor module reads the data from the sensor plate to process and convert it into analog output (Analog) or digital output (Digital). . Therefore, the output generated by the rain sensor will have two signal types, analog (Analog-AO) and digital (Digital-DO).
For the rain sensor circuit, it will consist of 2 parts:
The rain sensor is mounted outdoors
The programming circuit and sensitivity adjustment need to be shielded
Principle of operation
The rain sensor operates on the principle of comparing the voltage of the outdoor sensor circuit with a predetermined value (this value can be changed through a blue variable resistor), thereby emitting a relay on/off signal. crawl over DO's leg.
When there is water on the sensor surface (it rains), the conductivity is better and creates less resistance, the DO pin is pulled low (0V), the red LED will light up. Similarly, when the sensor is dry (it is not raining), the conductivity is poor and the resistance is high, the DO pin of the rain sensor module is kept high (5V-12V). So the output of the rain sensor mainly depends on the resistance. We should use low level relays with sensors.
Magnetic sensors
Structure
Structure of magnetic sensor: magnetic sensor will be divided into inductor, sensor and signal processor; control output.
Principle of operation
When powered, current will flow through a circuit containing an inductor as the magnetic field across it changes. This effect is used to detect metallic objects interacting with magnetic fields. Non-metallic substances such as liquids or dirt will not interact with the magnetic field. Therefore, magnetic sensors can work well in dusty environments or in humid conditions.
The larger the size and cross-section of the magnetic sensor, the stronger the magnetic field emitted; This means the larger the area it can detect objects; The efficiency it brings will be higher.
Optical sensors
Structure
Optical sensors are made up of 3 parts: light emitter, light receiver and electrical signal processing board.
Light emitter: This part takes on the position of the photothermal sensor, emitting pulsed light. Depending on each manufacturer, there will be a separate light frequency designed. This part complements the light receiver part to distinguish light sources from sensors and many other sources.
Light receiver: This part is the part that receives light and then transmits the signal to the processing part.
Electrical signal processing circuit: This part receives the signal from the light receiver and converts the signal according to the transistor ratio into ON/OFF mode, this signal has a wider amplification.
