If we want the security light to be turned on, we can create a logical expression that combines the sensor readings for light and motion. Let's say L represents the light sensor reading and M represents the motion sensor reading.
A logical expression that would be true when the security light should be turned on could be:
(L < threshold) AND (M > 0)
In this expression, L < threshold represents the condition that the light sensor reading is below a certain threshold value, indicating low light. M > 0 represents the condition that the motion sensor reading is greater than zero, indicating motion is detected.
So, when both conditions are met (low light and motion detected), the logical expression would evaluate to true, indicating that the security light should be turned on.
