What is meant by smart sensor?
A smart sensor is a device that takes input from the physical environment and uses built-in compute resources to perform predefined functions upon detection of specific input and then process data before passing it on. Compute resources are typically provided by low-power mobile microprocessors.
What is smart sensors Wikipedia?
From Wikipedia, the free encyclopedia. Smart sensor may refer to. Smart transducer, an analog or digital transducer or actuator combined with a processing unit and a communication interface. A more general term for smart cameras.
What is the importance of smart sensor?
With smart sensors, it is possible to improve the efficiency of building utilities like electricity, cooling, heating, lighting, and more through a connected environment that allows remote control and monitoring of all the devices.
What is the difference between sensor and smart sensor?
The difference between a normal sensor and a smart sensor is that a smart sensor is embedded with a Digital Motion Processor or DMP. A smart sensor can accept input from external sources and use pre-built functions to detect a specific combination of inputs. A regular sensor does not include a DMP.
What are the features of smart sensor?
Smart sensors provide the features – self identification, smart calibration and compensation, digital sensor data, multi sensing ability, sensor communication for remote monitoring and remote configuration, etc…
Which sensor is intelligent sensor?
To qualify as an intelligent sensor, the sensor and processor must be part of the same physical unit. A sensor whose only function is to detect and send an unprocessed signal to an external system which performs some action is not considered intelligent.
What are the characteristics of intelligent sensor?
While the basic sensor can only sense and emit unprocessed signals to an outer system, the intelligent sensor is designed with numerous functions such as self-identification, self-testing, self-confirmation or self-adaptation. It can perceive, reason, compute, and communicate.
What are the characteristics of smart sensors?
Where smart sensors are used?
Smart sensor technologies have been used for monitoring and control mechanisms in a wide variety of environments, including smart grids, flood and water level monitoring systems, environmental monitoring, traffic monitoring and control, energy saving in artificial lighting, remote system monitoring and equipment fault …
What is a smart sensor?
In the machine vision field, a single compact unit which combines the imaging functions and the complete image processing functions is often called a smart sensor. They are often made using CMOS, VLSI technology and may contain MEMS devices leading to lower cost.
What is an intelligent image sensor?
The vision system and the image sensor can be integrated into one single piece of hardware known as intelligent image sensor or smart image sensor.
What is a smart camera?
A smart camera is a self-contained, standalone vision system with built-in image sensor in the housing of an industrial video camera. The vision system and the image sensor can be integrated into one single piece of hardware known as intelligent image sensor or smart image sensor.
What is a smart transducer?
A smart transducer is an analog or digital transducer, actuator or sensor combined with a processing unit and a communication interface. As sensors and actuators become more complex they provide support for various modes of operation and interfacing. Some applications require additionally fault-tolerance and distributed computing.
