Tire pressure monitoring systems (TPMS) are relatively new additions to your car’s suite of sensors. At least if you’re old enough to remember when keeping an eye on tire pressures was boasted about ...

Window sensors are a critical part of any home security system. When cameras fail, a window sensor becomes your last line of defense. Install them on all your windows, and you will know when an ...

If you were asked to design a camera sensor, you'd naturally put the photo receptors on top, closest to the light. Oddly enough, because of the way chips are fabricated, until recently most camera ...

You might think traffic light systems are fairly basic. After all, electric traffic signals first appeared all the way back in 1914. However, they have advanced significantly since their inception, ...

Contact sensors, often known as door or window sensors, use magnets to sense open or closed states. You can use this information and the changing of these states to do all sorts of neat things in your ...

Curious about how cadence sensors work and how to use them effectively? This hands-on guide breaks down the basics of cadence sensing—from the core principles behind pedal rotation tracking to ...

Cameras keep getting better, but it sometimes feels like the pace of improvement has slowed. You can look at photos from the original Canon 5D, released in 2005, and they look pretty good! In some ...

A research team, including Huanyu "Larry" Cheng, James L. Henderson Jr. Memorial Associate Professor of Engineering Science ...

Thermopile sensors offer a reliable way to measure temperature without physical contact, making them ideal for real-world applications where speed, safety, and precision matter. Whether you are ...

This unit introduces students to programmable sensor technologies that can be used as tools to investigate, monitor, and communicate classroom environmental data (e.g. temperature, humidity, sound ...
