Industrial and commercial temperature sensors are typically separated from a controller ... Most materials used to manufacture RTD possess a positive α value meaning that resistance increases with an ...

Modern brake pad wear sensors not only help drivers plan maintenance, but they also make it easier for shops to keep customers informed about the condition of their brake pads. Stay on top of the ...

A Thermocouple is a terrific way to measure temperature. The effects of temperature change on dissimilar metals produces a measurable voltage. But to make that measurement you need an amplifier ...

Both sensors measure rate of change; they just measure the rate of change for different things. In practice, that means that an accelerometer will measure the directional movement of a device but ...

Most digital SLRs have 'crop' sensors, meaning their size is smaller than the traditional or 'full frame' area common in the 35mm film era. Full frame cameras provide a little more than 2.5 times ...

This one is a one-inch sensor, meaning there's plenty of room for big, light-hungry pixels. This means better results in all conditions but especially in lower-light situations. This is a small ...

Josh Howard of Denver calls riding RTD, which he does most days, “highway robbery” because he never knows whether his bus or train will be on time – or whether it will arrive at all.

As a frequent user of RTD, I've experienced firsthand the frustrations of its service. Rather than simply voicing my concerns, I decided it was time to take action. With my background as a Fortune ...

The lens is designed for APS-C sensors, meaning the 23mm focal length is the equivalent of 35mm on full-frame bodies – a common focal length for street photography and reportage, and a great all ...

If you want the best cameras in a drone, get this model. Its main camera has a larger sensor than that of our top pick, and it adds 70mm- and 166mm-equivalent lenses to capture more-distant subjects.
