Oxygen sensors detect the amount of oxygen in the exhaust. Oxygen sensors usually don’t have a replacement schedule. A bad oxygen sensor can be diagnosed with a code reader or scan tool. A car’s ...

If you build engines, tune cars, or even just like mashing your foot on the throttle with conviction, you’ve probably heard the term “wideband O2 sensor” being thrown around at the track, dyno ...

We tested popular wideband O₂ controllers against lab-grade equipment to see how accurate their lambda readings really are ...

The godfather of the active-pixel CMOS sensor, Eric R Fossum, PhD, has been awarded the 2026 Charles Stark Draper Prize for ...

Two months after coming out of stealth with a $150 million fundraise, Boston-based Teradar is showing off its first flagship terahertz sensor at Consumer Electronics Show 2026 this week. The company ...

A new lens-free imaging system uses software to see finer details from farther away than optical systems ever could before.

The U.S. Department of Energy's (DOE) Oak Ridge National Laboratory has released a new version of its advanced slicing ...

2026 smartphone cameras are set to redefine mobile photography with powerful AI processing, larger sensors, and DSLR-like controls. Smartphone cameras are developing at a rate like never before with ...

Optical sensors are a broad class of device for detecting light intensity. This can be just a simple component for notifying when ambient light levels rise above or fall below a prescribed level, or a ...

Nanosensors are chemical or mechanical sensors that can be used to detect the presence of chemical species and nanoparticles, or monitor physical parameters such as temperature, on the nanoscale. They ...

Abstract: Aiming at the demand of oxygen partial pressure measurement in aerospace and aviation, a tunable diode laser absorption spectroscopy (TDLAS) technique is proposed to realize the oxygen ...
