1. Understanding Sensor Technology

Modern sensors act as the "sensory organs" of our living spaces. These innovative devices detect environmental changes like motion, temperature, and light intensity. When you walk into a room and the lights turn on automatically, or when your thermostat adjusts to perfect comfort - that's sensor technology at work.
