Types Of Human Body Sensors

Thermometers translate the expansion of a fluid or bending of a metal strip in response to heat into a number corresponding to body temperature.

Types of human body sensors. In your eyes you have two different types of light sensors. We live in a world of sensors. Working to make our lives easier by turning on the lights by detecting our presence adjusting the room temperature detect smoke or fire make us delicious coffee open garage doors as soon as our car is near the door and many other tasks. The other type called cones can sense colors and actually there are three different types of cones for the three primary colors and require fairly intense light to be activated.

In the past few years body worn sensor based har has made promising progress in. You can find different types of sensors in our homes offices cars etc. Taking this approach enables students to view the human body as a system that is from the perspective of an engineer. One set of sensors called the rods senses light intensity and works well in low light situations.

Therefore in this work we propose an effective and efficient system that is able to recognize a human s physical activities automatically through analysis of the signals acquired in real time from multiple body worn or body embedded inertial sensors. A sensor converts the physical parameter for example. This lesson highlights the similarities between human sensors and their engineering counterparts. Humans have recreated most human sensors in robots eyes ears and sensors for temperature touch and smell.

Sensors are sophisticated devices that are frequently used to detect and respond to electrical or optical signals. Temperature blood pressure humidity speed etc into a signal which can be measured electrically sensor can be defined as an element that senses in one form of energy to produce a variant in same or another form of energy.
