In response to our understanding of the health concerns … type of thermometer consists of a U-shaped glass tube filled with a liquid. Photo: You can measure humidity with your smartphone, but only if it has a built-in moisture detector (or one connected to it). To understand how a thermometer works, we need to keep one thing in mind from physics: that a liquid expands in volume (the amount of space it takes up) when its temperature warms and decreases in volume when its temperature cools. Infrared thermometers work based on a phenomenon called black body radiation. ( Log Out /  The term is derived from the Greek word anemos, which means wind, and is used to describe any wind speed instrument used in meteorology.The first known description of an anemometer was given by Leon … How does it work? When temperature rises, the expansion force pushes the mercury through the constriction. The small sensor can be covered with disposable plastic casings for hygiene, and is placed into the ear and pointed down toward the cheekbone. To measure relative humidity, the difference in the temperatures of the dry and wet thermometers was calculated. expansion and contraction of alcohol.
