Industry and organizations have long used a variety of sensors, but the invention of the Internet of Things has brought the development of sensors to a completely different level. The Internet of Things platform can use a variety of sensors to run and provide a variety of intelligence and data. They are used to collect data, push data and share data with the entire network of connected devices. All of these collected data enable devices to operate independently, and the entire ecosystem is becoming "smarter" every day.
Let's look at some of the key sensors that are widely used in the world of the Internet of Things.
"A device for measuring thermal energy, which allows the detection of physical changes in temperature from a particular source and converts data for the device or user, is called a temperature sensor." These sensors have been running in a variety of devices for a long time. However, with the advent of the Internet of Things, they found more space in more devices.
Only a few years ago, their use mainly included A/C control, similar equipment for environmental control. However, with the advent of the Internet of Things world, they have found their own roles in the manufacturing process, agriculture and health industries. In the manufacturing process, many machines need specific ambient temperature and equipment temperature. Through this measurement, the manufacturing process can always be in the best condition. On the other hand, soil temperature is very important for crop growth in agriculture. This helps plant production and maximizes yield.
It can detect the existence of nearby objects or their attributes and convert them into signals. Users or simple electronic instruments can easily read them without contacting them.
Proximity sensors are widely used in the retail industry because they detect movement and the correlation between customers and products they may be interested in. Inform users immediately about the discount and special price of nearby products.
Vehicles are another large and fairly old use case. You are reversing and you feel uncomfortable with obstacles when reversing. This is the work of proximity sensors. They are also used to provide parking spaces in shopping malls, stadiums or airports.
Pressure sensor is a device that senses pressure and converts it into electrical signal. Here, the amount depends on the level of pressure applied.
There are many devices that rely on liquid or other forms of pressure. These sensors make it possible to create an Internet of Things system that monitors pressure-driven systems and devices. In case of deviation from the standard pressure range, the equipment will notify the system administrator of any problems to be solved. Deployment of these sensors is not only very useful in manufacturing, but also in the maintenance of the entire water system and heating system, because it is easy to detect any fluctuations or decreases in pressure.
The water quality sensor is mainly used for water quality detection and ion monitoring in water distribution system.
Water is actually used everywhere. These sensors play an important role in monitoring water quality for different purposes. They are used in various industries.
Chemical sensors are used in many different industries. Their goal is to point out changes in liquids or chemical changes in the air. They play an important role in larger cities. In these cities, it is necessary to track changes and protect the population.
Chemical sensors can be mainly embodied in industrial environmental monitoring and process control, detection of hazardous chemicals released intentionally or unintentionally, detonation and radioactivity detection, space station, recovery process in pharmaceutical industry and laboratory.
Gas sensors are similar to chemical sensors, but they are specially designed to monitor changes in air quality and detect the presence of various gases. Like chemical sensors, they are widely used in manufacturing, agriculture and health industries, as well as in air quality monitoring, toxic or flammable gas detection, harmful gas monitoring in coal mines, oil and gas industry, chemical laboratory research, paint manufacturing, plastics, rubber, pharmaceuticals and petrochemical industries.
Smoke sensor is a device that senses smoke (particulates and gases in the air) and its level.
They have been in use for a long time. However, with the development of the Internet of Things, they are now more effective, because they have been inserted into the system, which can immediately inform users of any problems occurring in different industries.
Smoke sensors are widely used in manufacturing, HVAC, buildings and infrastructure to detect fire and gas accidents. This protects people working in dangerous environments because the whole system is much more effective than the old system.
Infrared sensor is used to detect some characteristics of the surrounding environment by transmitting or detecting infrared radiation. It can also measure the heat emitted by an object.
They are now used in various IoT projects, especially in the area of health care, because they make it easy to monitor blood flow and blood pressure. They are even used in various conventional intelligent devices, such as smart watches and smart phones. Other common uses include household appliances and remote controllers, breath analysis, infrared vision (i.e., thermal leakage in visual electronic devices, monitoring blood flow, art historians to view below the paint layer), wearable electronic devices, optical communications, non-contact temperature measurements, car blind angle detection.
A sensor used to determine the level or quantity of liquid, liquid or other substances flowing in an open or closed system is called a level sensor.
They are mainly used to measure fuel consumption, but also for companies dealing with liquid materials. For example, the recycling industry and the juice and alcohol industries rely on these sensors to measure the amount of liquid assets they own. The best use cases of liquid level sensors are to open or close the electrical monitoring and liquid level in containers, sea level monitoring and tsunami warning, water tanks, medical equipment, compressors, hydraulic tanks, machine tools, beverage and drug processing, high or low level detection, etc.
Image sensor is an instrument for converting optical images into electronic signals to display or store documents electronically.
Image sensors are mainly used in digital cameras and modules, medical imaging and night vision equipment, thermal imaging equipment, radar, sonar, media room, biometric and IRIS equipment.
There are two main types of sensors: CCD (Charge Coupled Device) and CMOS (Complementary Metal Oxide Semiconductor) imagery. Although each type of sensor uses different techniques to capture images, both CCD and CMOS imagers use metal oxide semiconductors with the same sensitivity to light and no inherent quality differences.
Motion detector is an electronic device that detects physical motion (motion) in a given area and converts it into electrical signals. The movement of any object or human being.
Motion detection plays an important role in the safety industry. Enterprises should never use these sensors in areas where movement is detected, and it is easy to notice the presence of anyone who installs them. These are mainly used in intrusion detection system, automatic door control, arm barrier, intelligent camera (i.e. motion-based capture/video recording), toll plaza, automatic parking system, automatic flume/toilet washer, hand dryer, energy management system (i.e., automatic lighting, AC, fan, electrical control, etc.).
Accelerometer is a kind of sensor, which is used to measure the physical or measurable acceleration of an object due to inertial force, and to convert mechanical motion into electrical output. Defined as the rate of change of velocity relative to time
These sensors are now in millions of devices, such as smart phones. Their use usually involves the detection of vibration, tilt and acceleration. This is ideal for monitoring your driving team or using an intelligent pedometer. In some cases, it is used as a form of anti-theft protection, because if an object is moved that should remain stationary, the sensor can send an alarm through the system.
They are widely used in honeycomb and media equipment, vibration measurement, automobile control and detection, free fall detection, aircraft and aviation industry, sports detection, sports institute/athlete behavior monitoring, consumer electronics products, industrial and construction sites, etc.
Sensors or devices used to measure angular velocity or angular velocity are called gyroscope sensors. Angular velocity is simply defined as the measurement of rotational speed around an axis. The device is mainly used for navigation and measurement of angular velocity and rotation speed in 3-axis direction. The most important application is to monitor the direction of the object.
Their main applications include automobile navigation system, game controller, cellular and camera equipment, consumer electronics products, robot control, UAV and RC control helicopter or UAV control, vehicle control/ADAS, etc.
Humidity is defined as the amount of water vapor in air or other gaseous atmosphere. The most commonly used term is "relative humidity (RH)".
These sensors usually follow the use of temperature sensors, because many manufacturing processes require perfect working conditions. By measuring humidity, the whole process can be ensured to run smoothly, and when any sudden change occurs, measures can be taken immediately, because the sensor can detect the change almost immediately. Their applications and applications can be used in heating, ventilation and air conditioning system control in industrial and residential areas.
A sensor that measures the physical quantity of light and converts it into an easy-to-read electrical signal for users or electronic instruments/devices is called an optical sensor. Optical sensors are popular with Internet of Things experts because they can measure different objects at the same time. The technology behind the sensor enables it to monitor electromagnetic energy, including electricity, light and so on.
These sensors have been used in health care, environmental monitoring, energy, aerospace and many other industries. With the presence of oil companies, pharmaceutical companies and operators, they can better track environmental changes while maintaining staff safety.
Their main uses can be found in environmental light detection, digital optical switch and optical fiber communication, because they are most suitable for oil and natural gas applications, civil and transportation fields, high-speed network systems, elevator door control, assembly line counters and electrical isolation. Safety system.
As the platform becomes smarter by fusing all the sensors mentioned above, we have not yet seen the full potential of this technology. Given the fact that all measurements have been collected and analyzed, it is clear that the Internet of Things will become more intelligent in the future.
