Content

Understanding Basic Sensors

1. Definition of a Sensor: A sensor is a device that detects or measures a physical property and records, indicates, or responds to it.
   • Example: A light sensor detects the presence or absence of light.
2. Common Types of Sensors:
   • Light Sensor: Detects light and darkness.
   • Temperature Sensor: Measures temperature.
   • Motion Sensor: Detects movement.
   • Proximity Sensor: Detects nearby objects.
3. Basic Function of Sensors:
   • Sensors collect data from their surroundings.
   • Sensors send signals to a device (e.g., a robot or computer).
   • Example: A light sensor sends a signal to turn on a light when it gets dark.
4. Demonstration Activity:
   • Activity: Show how a light sensor works by covering and uncovering it to change the light’s behavior.
   • Explanation: Discuss how sensors are used in everyday devices and robots.
