Sensor

Sensor Description

A sensor detects and converts physical quantities into measurable signals. It works by applying specific principles or technologies. Each sensor has unique features that distinguish it from others.

For example, a temperature sensor measures temperature. It converts temperature changes into electrical signals. Its key features include a wide measurement range, high accuracy, and fast response time.

Technical Specifications

Technical specifications provide detailed performance characteristics. Common specifications include:

• Measurement Range: The minimum and maximum values the sensor can measure accurately.
• Accuracy: The sensor’s conformity to the actual value of the measured quantity.
• Resolution: The smallest change the sensor can detect.
• Sensitivity: The output change per input change ratio.
• Response Time: The time taken for the sensor to respond to a change.
• Operating Temperature: The temperature range for reliable operation.
• Power Consumption: The amount of power required for operation.
• Output Signal: The type of signal generated (e.g., analog, digital).
• Interface: The connection method to other devices (e.g., I2C, SPI).
