What it measures: These use infrared sensors that measure light in the air, because this is inversely proportional to the amount of CO2. As such, these sensors can give a fairly accurate ...

An infrared temperature sensor is a tool I would like to add as another essential tool to your press room. They cost only about $100 which is very little in comparison to the payback they offer. I ...

The blood oxygen sensor is composed of four LED clusters and four photodiodes integrated into the back of your watch case. The green, red, and infrared LEDs shine light onto the blood vessels in ...

Why Your Smartphone Needs an Infrared Sensor You could use a heat sensor to check your house for leaks, for instance. But mostly, it's a lot of fun.

Researchers have finally figured out how mosquitoes see humans in the dark: They detect infrared light the body generates via heat.

Ear thermometers take a person's temperature using an infrared sensor. Learn more about their accuracy, how to use them, and alternative methods here.

Forehead thermometers use infrared sensors to pick up on infrared radiation that the body produces. Although infrared radiation is not visible, a person may be able to feel it as heat.

Ever wonder how to calculate revolutions per minute using a microcontroller? This project shows you how by purposing an IR emitter and detector and a computer fan. As the fan blades spin they disru… ...

Enhanced Vision Systems (EVS) use infrared sensors to provide pilots with increased situational awareness in low-visibility conditions, day or night. EVS cameras detect the heat of objects ...
