What is a sensor?
A sensor is a device or element that collects information on an
object and converts it to a signal that can be processed by a
machine.
Like humans that behave based on information obtained from their
senses (visual, auditory, taste, touch, smell), machines operate
(controls/processes) utilizing information from sensors.
Signals (physical quantities) that sensors collect and convert are
varied and include temperature, light, color, atmospheric pressure,
acceleration, and speed.
These types generally take advantage of material changes in
semiconductors. There are also bio sensors that adopt biological
substances such as enzymes and microorganisms.
IoT and Sensors
IoT (Internet of Things) refers to a network of devices connected to
the Internet.
In addition to communications equipment such as smartphones and PCs,
medical devices, wearables, vehicles, the natural environment, and
infrastructure share information on the web, resulting in a
connected society that leads to greater convenience, comfort, and
security.
What is needed to achieve this are sensors that can detect various
conditions.
[Terminology related to IoT]
IoT: Internet of Things
A concept that involves embedding sensors in wearable devices and connecting them to the Internet to enable communication between each other, people, and other devices.
Industry 4.0 (Germany)
A project jointly promoted by the government, industry, and academia
in Germany aimed at the advancement of the manufacturing
industry.
The goal is to revitalize businesses by creating new concepts and
value through connected factories.
M2M: Machine to Machine
Technology used to enable networked devices to communicate directly
without human intervention.
P2M: People to Machine
M2P: Machine to People
Industrial Internet
IoT strategies in industries advocating GE (General Electric Corp.)
as its core.
Data collected from a variety of devices, termed ‘Big Data’ is
analyzed and utilized for next-generation product development. The
emphasis is on products and services.
