MEMS Sensor
Micro-electromechanical device integrating miniaturized mechanical elements and electronic circuits on the same silicon chip, used to measure physical parameters such as acceleration, pressure, or vibration in industrial equipment.
IoT Gateway
Hardware or software equipment that acts as a central connection point between IoT sensors and the cloud, ensuring data aggregation, protocol translation, and information preprocessing at the network edge.
Fieldbus
Industrial digital communication network that connects sensors, actuators, and programmable logic controllers, replacing traditional point-to-point connections for more robust and centralized data acquisition.
Sensor Resolution
Smallest measurement increment that a sensor can detect and represent, expressed in bits for digital sensors, determining the fineness and accuracy of collected data for state analysis.
Data Latency
Time delay between data collection by a sensor and its availability for analysis or decision-making, a critical factor for the effectiveness of real-time alerts in predictive maintenance.
Telemetry
Technology for automatic collection and transmission of remote measurement data, essential for monitoring the status and performance of industrial equipment from a centralized control center.
Signal Filtering
Set of signal processing techniques applied to raw sensor data to eliminate noise, artifacts, and interference, thereby improving the signal-to-noise ratio before predictive analysis.
Sensor Calibration
Adjustment and validation procedure that aligns a sensor's output to precisely match a known reference value, ensuring the reliability and accuracy of measurements over the long term.
Sensor Redundancy
Deployment of multiple sensors to measure the same variable or monitor a critical point, enabling cross-validation of data and ensuring continuous monitoring in case of sensor failure.
MQTT Protocol
Lightweight publish/subscribe-based messaging protocol, optimized for low-bandwidth communications and high-latency environments, ideal for transmitting IoT sensor data to cloud platforms.
Data Aggregation
Process of collecting and combining data from multiple sensor sources, often at the gateway or edge, to form a consolidated dataset before sending it to the central analysis system.
Industrial Accelerometer
Type of MEMS or piezoelectric sensor designed to measure vibrations and shocks on rotating machinery, providing crucial spectral data for diagnosing faults such as imbalance or bearing defects.
Sensor Node
Autonomous entity in a wireless sensor network, consisting of one or more sensors, a microcontroller, a radio, and a power source, responsible for local collection and transmission of environmental or operational data.
Data Rate
Volume of data generated by a sensor or transmitted over the network per unit of time (e.g., in bits per second), a key parameter to optimize for balancing information richness with bandwidth or energy constraints.
Measurement Range
Range of minimum and maximum values that a sensor can measure accurately, the selection of which must be adapted to the expected operating conditions of the monitored equipment to avoid saturation or lack of sensitivity.
