Uses of Infrared Technology Radiation

One of the most common uses of infrared radiation is in heat-sensitive thermal imaging cameras.

 These can be used to study human and animal body heat patterns, but more often, they are used as night-vision cameras.

 These have uses in warfare, as security cameras and in nocturnal animal research.

Most remote controls operate by sending pulses of infrared, spelling out codes that an electronic device will recognize.

 This includes TV remotes, DVD players, projectors, etc. Infrared is often used to send signals through fiber optic cables, particularly when using standard silica fibers. Fiber optic cables are commonly used to transmit audio to sound systems and for high-speed Internet connections.

Infrared is also widely used in astronomy. Taking pictures of the universe in infrared can lead to some amazing discoveries.

 Astronomers can look at an area of the sky that appears empty and dark in the visual part of the electromagnetic spectrum and find the area full of activity in the infrared. Since most objects that are at all hot produce infrared radiation, whereas plenty of objects do not produce visible light, it is a vital tool in observational astronomy.

Image
  Unmanned Power Sub Station System An Unmanned Power Substation System refers to a modern and technologically advanced electrical substation that operates without the need for constant on-site human presence. These unmanned substations utilize automation, remote monitoring, and control technologies to efficiently manage potential events. Automation and Remote Control The system is equipped with intelligent devices and sensors that automate various tasks such as monitoring voltage, current, temperature, and other parameters. Remote control capabilities allow operators to manage the substation from our command center. Reduced Operation and Maintenance Costs With the elimination of on-site personnel, the operational and maintenance costs associated with manned substations are significantly reduced. Routine maintenance tasks can be scheduled and monitored remotely. Enhanced Reliability and Safety The use of automated systems ensures greater reliability and minimizes the risk of human ...

  Arduino Uno (R3) The Uno is a huge option for your initial Arduino. This Arduino board depends on an ATmega328P based microcontroller. As compared with other types of arduino boards, it is very simple to use like the Arduino Mega type board. .It consists of 14-digital I/O pins, where 6-pins can be used as PWM( pulse width modulation  outputs), 6-analog inputs, a reset button, a power jack, a USB connection, an In-Circuit Serial Programming header (ICSP), etc. It includes everything required to hold up the microcontroller; simply attach it to a PC with the help of a USB cable and give the supply to get started with an AC-to-DC adapter or battery. Arduino Uno (R3) Arduino Uno is the most frequently used board and it is the standard form apart from all the existing Arduino Boards. This board is very useful for beginners. Please refer to this link to know more about  Arduino Uno Board
