RFID

-

 Radio Frequency Identification (RFID) is a form of wireless communication that incorporates the use of electromagnetic or electrostatic coupling in the radio frequency portion of the electromagnetic spectrum to uniquely identify an object, animal or person.

 It uses radio frequency to search ,identify, track and communicate with items and people. 

it is a method that is used to track or identify an object by radio transmission uses over the web. 

Data digitally encoded in an RFID tag which might be read by the reader. 

This device work as a tag or label during which data read from tags that are stored in the database through the reader as compared to traditional barcodes and QR codes.

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
