Optical sensors and their applications
Generally, we use conventional wall socket switchboards for switching on industrial appliances or home appliances such as fan, cooler, industrial motors, and so on. But, it is very difficult to operate the switches regularly. Hence, home automation and industrial automation systems are developed for ease of controlling all the required electrical and electronics loads. This automation in a power system can be designed using various types of sensors and sensor circuits. So, this article gives a comprehensive overview of what is a sensor, different types, principle along with circuit diagrams.
Welcome to Thomasnet. Below you will find comprehensive information on the types of products, their suppliers and manufacturers, sensor applications in industry, considerations, and important attributes. Many types of sensors, detectors, and transducers are available including those for detecting a physical presence such as flame, metals, leaks, levels, or gas and chemicals, among others. Some are designed to sense physical properties such as temperature, pressure, or radiation, while others can detect motion or proximity. They operate in a variety of manners depending on the application and may include electromagnetic fields, or optics, among others. Many applications over a wide range of industries use sensors, detectors, and transducers of many kinds to test, measure, and control various processes and machine functions.
Sensors are sophisticated devices that are frequently used to detect and respond to electrical or optical signals. A Sensor converts the physical parameter for example: temperature, blood pressure, humidity, speed, etc. This device collects information about temperature from a source and converts into a form that is understandable by other device or person. The best illustration of a temperature sensor is mercury in glass thermometer. The mercury in the glass expands and contracts depending on the alterations in temperature.
Know about Different Types of Sensors with their Applications
The sensor is an electronic device that measures physical attributes such as temperature, pressure, distance, speed, torque, acceleration, etc. These Signals are either interpreted into a readable format or passed on to the next stage for further processing. Sensors are broadly grouped into analog and digital sensors. Analog sensors measure the exact value of physical variables, whereas digital sensors measure the status. Applications classify sensors, Property sensed, Technology used and Systems where they are deployed. The ability of Sensors is to measure multi various data on the activities taking place within a system that throws open plenty of use cases. For example, the temperature sensor installed in a furnace measures the temperature data on a periodic interval and sends it to the controlling unit.
In our day-to-day life we fre quently use different types of sensors in several applications such as IR sensor used for operating television remote, Passive Infrared sensor used for automatic door opening system of shopping malls and LDR sensor used for outdoor lighting or street lighting system, and so on. In this article we will discuss about a few types of sensors and their applications in brief. But, primarily we must know what is a sensor. A device that detects the changes in electrical or physical or other quantities and thereby produces an output as an acknowledgement of change in the quantity is called as a Sensor. Generally, this sensor output will be in the form of electrical or optical signal. The most frequently used different types of sensors are classified based on the quantities such as Electric current or Potential or Magnetic or Radio sensors, Humidity sensor, Fluid velocity or Flow sensors, Pressure sensors, Thermal or Heat or Temperature sensors, Proximity sensors, Optical sensors, Position sensors, Chemical sensor, Environment sensor, Magnetic switch sensor , etc. Typical applications of different types of sensors such as application of Speed sensor for synchronizing the speed of multiple motors, Temperature sensor application for industrial temperature control, application of the PIR sensor for automatic-door-opening system, Ultrasonic sensor application for distance measurement, etc.

DOI: Optical Sensors are used in numerous research, and commercial applications today. These sensors are used for quality and process control, medico technologies, metrology, imaging, and remote sensing to mention a few examples.
We live in a World of Sensors. You can find different types of Sensors in our homes, offices, cars etc. All these and many other automation tasks are possible because of Sensors. Before going in to the details of What is a Sensor, What are the Different Types of Sensors and Applications of these different types of Sensors, we will first take a look at a simple example of an automated system, which is possible because of Sensors and many other components as well.
The world is full of sensors. In our day-to-day life, we come across automation in all the activities.
List of Sensors
Типичная для Испании туалетная комната: квадратная форма, белый кафель, с потолка свисает единственная лампочка. Как всегда, одна кабинка и один писсуар. Пользуются ли писсуаром в дамском туалете -неважно, главное, что сэкономили на лишней кабинке. Беккер с отвращением оглядел комнату. Грязь, в раковине мутная коричневатая вода. Повсюду разбросаны грязные бумажные полотенца, лужи воды на полу.
Дайте ему минутку прийти в. - Н-но… - Сьюзан произнесла слова медленно. - Я видела сообщение… в нем говорилось… Смит кивнул: - Мы тоже прочитали это сообщение. Халохот рано принялся считать цыплят. - Но кровь… - Поверхностная царапина, мадам. Мы залепили ее пластырем. Сьюзан лишилась дара речи.
Ему сказали, что бортовой телефон вышел из строя, поэтому позвонить Сьюзан не удастся. - Что я здесь делаю? - пробормотал. Ответ был очень простым: есть люди, которым не принято отвечать. - Мистер Беккер, - возвестил громкоговоритель. - Мы прибываем через полчаса. Беккер мрачно кивнул невидимому голосу. Замечательно.
