The concept of IR sensors is not new but many people are not aware of the types and uses of such sensors and end up not getting the desired result from it. There are some amazing options like excelitas IR sensors that can work the best for different applications. But before that, it is important to understand what exactly an Infrared sensor is all about and why it has gained popularity over some time now.
What is an infrared Sensor:
Also referred popularly as an IR sensor, the infrared sensor is a component of a radiation-sensitive optoelectronic solution. It comes with spectral sensitivity in the infrared wavelength range of 780 nm. Whether it is the motion detectors or the taking the car in reverse while driving it is the Infrared sensor that is used. It also helps in building services or even to switch the lamps or shutting the alarm system or alerting when there are guests not expected.
There is an angle range well defined in which the elements of the sensor will detect the radiation of the head. This is infrared radiation. It would change by space and time because of the movement. There are not many high requirements of this sensor because it is even the low-cost mass product available.
Types of Infrared Sensors:
The basic types of infrared sensors are two. The first one is the active infrared sensor and the other one is the passive sensor. The active sensor can emit and even detect infrared radiation. This sensor has two main parts & functions in an important way. The first one is the light-emitting diode which is LED and the other one is the receiver. If the object gets closer to the sensor, then there will be an infrared light from the LED. It will reflect the object and thus the receiver will be able to detect it. A passive infrared sensor on the other hand will detect infrared radiation. It will not emit it from the LED.
There is also a pyroelectric IR sensor in which there is a wavelength used. It ranges from 2 to 14 µm. The pyroelectric IR sensor is used in detecting motion-based systems like an in-home security system. If there is a moving object that creates the infrared radiation, it enters the range of sensing of the detector. This way the IR level difference between the two elements of pyroelectric is measured. The sensor would then send the electronic signal to the computer that will then turn the alarm on. There are also other infrared sensor options such as bolometers, Golay cells, and even thermopiles.
There are so many companies that are considered to offer the most amazing solutions in terms of Infrared solutions. However, an option like excelitas IR sensors latest version is a must-try. The 4.1 version comes with the whole thermal detection solution that can be used for detecting gas, measuring the temperature, and even understanding the monitor presence. It is one cost-friendly option that should be chosen for betterment.
