Introduction to Sensors: Types, Functions, and Applications - JSS3 Basic technology Lesson Note

Sensors are devices that detect and respond to physical stimuli such as light, heat, motion, or pressure, converting them into electrical signals. Types of sensors include temperature sensors, proximity sensors, and accelerometer sensors. They play crucial roles in various applications such as environmental monitoring, healthcare, and automotive industries. For example, temperature sensors ensure precise climate control in smart homes, while proximity sensors enable touchless interfaces in smartphones.
