What Is a Vibration Sensor? A vibration sensor, commonly known as a piezoelectric sensor, converts mechanical vibrations into electrical signals. By exploiting the piezoelectric effect, it transforms acceleration, pressure, or strain into a measurable voltage, enabling precise monitoring of dynamic

The unit of illuminance, lux, is the internationally accepted measure of ambient light. Typical ambient light sensors can detect levels from below 50 lux—typical of a dim interior—to over 10,000 lux, the brightness of a midday sun. One lux equals one lumen per square meter, allowing photometric meas

Fingerprint recognition has become a cornerstone of modern authentication, offering rapid, cost‑effective, and highly consistent identification. Each individual’s fingerprint is a unique pattern of ridges and valleys, forming whorls, loops, arches, and tented arches that are distinct and difficult t

Soil moisture is a pivotal factor in irrigation and horticulture. It determines nutrient availability, influences plant transpiration and root development, and can create anaerobic conditions that favor pathogenic growth. Accurate soil moisture monitoring enables precise water management, leading to
