Smart sensors are sensors with information processing capabilities. They are equipped with microprocessors, enabling them to collect, process, and exchange information. This integration of sensors and microprocessors results in enhanced functionality compared to general sensors. Smart sensors have the following three advantages: high-precision information collection through software technology at a low cost; a certain level of programming automation capability; and diversified functionalities.A good ‘smart sensor’ is a sensor and instrument set driven by a microprocessor, featuring communication and onboard diagnostic functions.Smart sensors can store various physical quantities detected and process this data according to instructions, thereby creating new data. Smart sensors can communicate with each other, autonomously decide which data to transmit, discard abnormal data, and complete analysis and statistical calculations.Smart sensors are computer detection systems with microprocessors at their core, extending the peripheral components. Compared to general sensors, smart sensors have the following significant characteristics:1. Improved Sensor AccuracySmart sensors possess information processing capabilities, allowing software to correct various deterministic system errors (such as nonlinear output errors, calibration errors, zero-point errors, and forward and reverse stroke errors) and appropriately compensate for random errors, reducing noise and significantly improving sensor accuracy.2. Enhanced Sensor ReliabilityThe miniaturization of integrated sensor systems eliminates certain unreliable factors of traditional structures, improving the entire system’s anti-interference capability; it also includes diagnostic, calibration, and data storage functions (with adaptive capabilities for intelligent structural systems), ensuring good stability.3. Improved Performance-Price Ratio of SensorsWith the same accuracy requirements, multifunctional smart sensors have a significantly improved performance-price ratio compared to single-function ordinary sensors, especially when using cheaper microcontrollers.4. Facilitation of Multifunctionality in SensorsSmart sensors can achieve comprehensive measurement of multiple sensors and parameters, expanding measurement and usage ranges through programming; they possess a certain level of adaptability, adjusting output data forms in response to changes in detection objects or conditions; they feature digital communication interfaces for direct processing by remote computers; and they support various data output forms (such as RS232 serial output, PIO parallel output, IEEE-488 bus output, and analog output after D/A conversion), making them suitable for various application systems.(Source: This article is reproduced from OFWEEK.
