You have a motion security light by your door. A cat run across it and the light turns on. What is the input of this system and what is the output?
I would say the system detected "the motion of the cat" and the result was that "the light turned on"
In the context of a motion security light, the input of the system is the presence of motion within its detection range. The output is the activation of the light, in this case, turning it on.
To understand this in more detail, let's break down the components involved:
1. Motion Sensor: The motion sensor detects changes in infrared radiation caused by moving objects within its range. When a living being, like a cat, passes in front of the sensor, it triggers an electrical signal.
2. Control Unit: The electrical signal from the motion sensor is sent to the control unit, which processes the signal and determines if it meets the conditions for triggering the output.
3. Light: The output in this case is the activation of the light. When the control unit determines that there is sufficient motion, it sends a signal to the light to turn it on.
So, to summarize:
Input: Motion detected by the motion sensor
Output: Activation of the security light
