IOT

A scenario I which objects, animals, and people are provided with unique identifiers and the ability to automatically transfer data over a network without requiring human to human or human to computer interaction

Universal Product Code (UPC)

A typical bar code made up of 12 digits that are batched in various groups. The first digit identifies the item type, the next five digits identify the manufacturer, and the next five identify the product. The last digit is a check digit for error detection.

Two basic types of RFID Tags

Active RFID: tags that use internal batteries for power, and they broadcast radio waves to a reader. Passive RFID: tags rely entirely on readers for their power, less expensive than active tags, and can be read only up to 20 feet.

Examples of IoT Use

Coke machines A heart monitor implant A farm animal with a biochip transmitter An automobile tire pressure

Advantages of QR codes (over bar codes)

QR codes can store much more information. • Data types stored in QR codes include numbers, text, URLs, and even Japanese characters. • QR codes are smaller because they store information both horizontally and vertically. • QR codes can be read from any direction or angle, so they are less likely to be misread. • QR codes are more resistant to damage.

Capabilities of IoT

Reducing waste, loss, and cost Identifying the need for repair, replacement, or recall Tracking expiration data on perishable items

Limitations of Bar codes

Require a line of sight to the scanning device Pose substantial problems in a manufacturing plant, warehouse or shipping/receiving dock can be ripped, soiled, or lost identifies the manufacturer and product but not the actual item

QR code

a two-dimensional code, readable by dedicated QR readers and camera phones

IOT

also called the Internet of everything, the Internet if anythung, the industrial internet, and machine to machine communication, is a system in which any object, natural or manmade has a unique identity(ie) it's own IP address and is able to send and rescieve info over a network (the Internet) without human interaction

wireless sensor networks (WSNs)

networks of interconnected, battery-powered, wireless sensors called motes placed in the physical environment

RFID Systems

tags have embedded microchips, which contain data, and antennas to transmit radio signals over a short distance to RFID readers including information that uniquely identifies an item (location and when it was made).

Radio Frequency Identification (RFID)

technology that allows manufacturers to attach tags with antennas and computer chips on goods and then track their movement through radio signals. RFID was developed to replace bar codes.
