Sensor

Answer 1

Many organisms, including humans and most animals, have biological temperature sensors. A biological temperature sensor serves essentially the same function as an artificial sensor: it collects data and transfers it into an understandable form. Human sensory nerves, for example, send sensory information from the skin to the brain in the form of electrical impulses. The brain produces the sensations of hot and cold that people experience while standing in the sun or walking through the snow. While the electrical impulses themselves would make no sense if set in front of an individual, the general feelings of hot and cold make perfect sense.
