One of the common causes of lost power and performance in diesel-powered vehicles is a malfunctioning nitrogen oxides (NOx) sensor. These sensors monitor NOx levels in the vehicle’s exhaust. If they ...

Adding noise to enhance a weak signal is a sensing phenomenon common in the animal world but unusual in manmade sensors. Now researchers have added a small amount of background noise to enhance very ...

Most modern digital cameras use CMOS tech to capture light, but not all are equally capable. We break down the various types of CMOS sensors and differentiate them from CCD and Foveon chips. Images, ...
