What are smart sensors used for?
Summary of the Article
Smart sensors are devices that use embedded microprocessors and wireless communication to monitor, examine, and maintain various systems. They have the ability to collect environmental data accurately with less noise. A smart sensor performs data conversion and digital processing before communicating with external devices. These sensors have various advantages, including self-testing, self-validation, self-adaptation, and self-identification. They also provide real-time data, precision and accuracy, and can work in harsh environments. Smart sensors perform functions such as measurement, configuration, verification, and communication. Examples of smart sensors include temperature sensors, pressure sensors, force sensors, vibration sensors, and humidity sensors. A sensor is a device that detects events or changes in its environment and relays the information to other electronics, typically a computer processor. The main difference between a normal sensor and a smart sensor is that the latter is embedded with a Digital Motion Processor (DMP). A regular sensor does not include a DMP. Smart sensors have both advantages and disadvantages. The complexity and cost of wired smart sensors are higher compared to other types. Additionally, the use of predefined embedded function and the requirement for actuators and external sensor calibration are some drawbacks of smart sensors.

What is the purpose of using sensors
A sensor is a device, module, machine, or subsystem that detects events or changes in its environment and relays the information to other electronics, most commonly a computer processor. A sensor converts physical phenomena into a measurable digital signal, which can then be displayed, read, or processed further.
What are the advantages of smart sensors
Intelligent sensors are able to carry out a number of intrinsically intelligent functions, such as the ability to self-test, self-validate, self-adapt, and self-identify. They understand process requirements, manage a wide range of conditions, and can detect conditions to support real-time decision making.
What are the 2 things smart sensors check for
These sensors have 4 main functions measurement, configuration, verification & communication. Measurements are simply taken through detecting physical signals & changing them into electrical signals. So this will help in monitoring and measuring things like temperature, traffic, & industrial applications.
What is the difference between a sensor and a 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 is a simple example for sensor
The simplest example of a sensor is an LDR or a Light Dependent Resistor. It is a device, whose resistance varies according to intensity of light it is subjected to. When the light falling on an LDR is more, its resistance becomes very less and when the light is less, well, the resistance of the LDR becomes very high.
What are the advantages and disadvantages of smart sensor
1) In wired smart sensors, complexity is much higher as a consequence the cost is also high. 2) Required use of predefined embedded function during the design of the smart sensor. 3) It requires both actuators and sensors. 4) Sensor calibration has to be managed by an external processor.
