sensors taxonomy

Sensors can be grouped based on the types of signals they detect, such as mechanical (pressure, vibration), thermal (temperature), optical (light, color), chemical (gases, liquids), and magnetic (magnetic fields). They are also classified by their function, like whether they measure physical quantities or detect specific substances. Additionally, sensors differ in how they send data—some produce electrical signals directly, others convert information into digital data for processing. This taxonomy helps organize sensors by what they sense and how they communicate, enabling selection of the right sensor for various applications like healthcare, automotive, or environmental monitoring.
