Next Generation Sensor

-

What are Next Generation Sensor and state their needs in industry 4.0.

It is the "smart sensors" which allows:

Integration of sensors and actuators with a processor and a communication module.

Defined in IEEE 1451 Standard as:

“Sensors with small memory and standardized physical connection to enable the communication with processor and data network”.

Functionalities - Self calibration, Communication, Computation, Multi-
sensing, Cost improvement.

It allows interoperability of networks, transducers and control systems of different manufacturers.

Compatibility of sensors with multiple sensor actuator bus standards, reducing wiring cost and complexity.

Interconnection of analog transducers with digital networks.

Increasing usage of existing networks instead of proposing new standards.

State the limitations of smart sensors.

Pre-defined embedded functions, customization not possible.
Narrow application spectrum.
Sensor data aggregation not possible.
External processor for sensor calibration.
Basic communication protocols.

To overcome these we can use "Intelligent sensors".

What is "Intelligent Sensors"?

"Intelligent Sensors" are:
Capable of processing sensed data and performing pre-defined functions by processing data.

Capable of customizing embedded algorithms on the fly.

Capable of managing and controlling external sensors/devices.

Comprises of a sensor, a microcontroller, a memory unit comprising of flash, RAM and ROM, and a platform for running sensor applications.

Write the advantages of "Intelligent Sensor".

Reduce data communication.
Reduced power consumption.
Application-specific customization of sensor nodes.
Continuous calibrating and monitoring of the sensors.
Adaptive sampling rate and sleep-wake cycles.
Shorter software development time.
Improved compatibility of sensors.

Introduction Of Sensing And Actuation

Que. What is Transducer? Imagine a translator , but for energy instead of languages . That's basically what a transducer is! It's a device that takes energy in one form and converts it into another form. In other words transducer convert a signal from one physical form to another physical form . (Physical form: thermal, electric, mechanical, magnetic, chemical and optical.) Example: Microphone: Convert electrical to sound signal. Speaker: Convert sound signal to electrical signal Antenna: Convert electromagnetic energy into electricity and vice versa. Que. What is Sensor? The characteristic of any device or material to detect a presence of a particular physical quantity . The output of a sensor is signal which is converted to human readable form. It performs some functions to input by sensing or feeling some physical changes in the characteristics of a system in response to the physical parameters such as temperature, sound, pressure, light, gas etc. Output: Response to phy...

What is Augmented Reality and Virtual Reality? From the technological perspective, Augmented Reality (AR) and   Virtual Reality (VR) are used in several contexts and sectors in  Industry 4.0. AR and VR plays important role in the primary stages where optimization   and productivity are important in manufacturing industry. The efficiency of warehouses are improved using various AR applications. AR and VR also plays an important role in safety training, thereby the p otential safety hazards can be easily located.
