Types of Sensors with Their Circuit Diagrams
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.
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 example we are talking about here is the Autopilot System in aircrafts. Almost all civilian and military aircrafts have the feature of Automatic Flight Control system or sometimes called as Autopilot.

History has shown that advancements in materials science and engineering have been important drivers in the development of sensor technologies. For instance, the temperature sensitivity of electrical resistance in a variety of materials was noted in the early s and was applied by Wilhelm von Siemens in to develop a temperature sensor based on a copper resistor. The high resonance stability of single-crystal quartz, as well as its piezoelectric properties, have made possible an extraordinarily wide range of high performance, affordable sensors that have played an important role in everyday life and national defense. More recently, a new era in sensor technology was ushered in by the development of large-scale silicon processing, permitting the exploitation of silicon to create new methods for transducing physical phenomena into electrical output that can be readily processed by a computer. Ongoing developments in materials technology will permit better control of material properties and behavior, thereby offering possibilities for new sensors with advanced features, such as greater fidelity, lower cost, and increased reliability.
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.
Different Types of Sensors
The world is full of sensors. In our day-to-day life, we come across automation in all the activities. Automation includes turning on lights and fans using mobile phones, controlling TV using mobile apps, adjusting the room temperature, smoke detectors, etc. All these are done with help of sensors.

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.
