One must breathe in with your olfactory sensor; on the human, that is the nose.
No reputable scientific information is available - showing that motion sensors harm human health.
Depends. Color, no; for they have no Green, Blue or Red sensor in their eyes.
Its a device or software that recognizes various human emotions, reactions and body gestures.
A PIR Motion sensor detects the minute changes in heat and infrared radiation rather than movement.
The principle of operation of any known sonic sensor (the human ear, for example) is detection of air vibration by measurement of its sensitive membrane oscillation frequency.
The human area network is implemented for wireless body area networks. It is embedded inside the body, as an implant, used as sensor devices.
As a filter and a sensor for the brain, when you smell something it sends signals to the brain telling you what it is you are smelling.
Yes. Occupancy sensor do sense the human movements in an open area with in the specified range. It is better to refer to the data sheet of a specific make, model to decide on the range. There are two types of occupancy sensors. Pyrotech Infra red (PIR) type or Ultrsonic type.
To remove foxes from your property you can use a few human tools. Motion sensor alarms as well as noise makers are great deterrents. You can contact your local human society for further direction.
The telescope itself doesn't see anything at all; it is the eye on the eyepiece, or the optical sensor, that "sees" things. Depending on how the optical sensor is designed, it may see the same range of colors that our own human eyes do, or may see a different, perhaps broader, range. But the telescope merely amplifies and magnifies the light. ALL of it.
No, the image sensor is not a MEMS flow sensor as many think.
