Is a motion detector considered an environmental sensor?

A motion detector is not considered an environmental sensor because its primary function is to detect movement or motion within a specified area rather than monitoring environmental conditions such as temperature, humidity, or air quality. Environmental sensors are specifically designed to provide information about the surrounding environment and may include devices that detect changes in light, temperature, moisture, or air pollutants. Motion detectors are focused on security functions, such as triggering an alarm when movement is detected, which distinguishes them from environmental sensors that serve different monitoring purposes. Thus, the assertion that a motion detector falls into the category of environmental sensors is not accurate.
