In a way, the magic of a soil moisture sensor’s functionality boils down to a simple RC circuit. But of course, in practice there is a bit more to it than that. [rbaron] explains exactly how … ...

That's a basic breakdown of what your car's MAP sensor does. However, if you're interested in learning more about how the sensor works, signs that it's gone bad, and how much it costs to replace ...

There are absolutely motion sensors that are meant to work outside. Many smart home doorbells and security cameras have built-in motion sensors that can connect to your smart lights.

Some motion sensors are based on optical measurement technologies to provide accurate velocity and position measurements without requiring physical contact with the object or surface being monitored.

How Do Oxygen Sensors Work? Oxygen sensors are a key part of the vehicle emissions system. They measure the differential oxygen levels between the outside air and the exhaust gas to generate a voltage ...

More and more keyboards and video game controllers employ Hall effect sensors, but what exactly is this technology? We break it down.

Basic board mount pressure sensors are compensated and unamplified so they can do their own amplification while retaining maximum resolution.

The primary purpose of this paper is to suggest basic crash sensor requirements which will form the basis for discussion of this subject. No attempt has been made in the body of this paper to suggest ...

The sensors and components on robocars will fail. Ford recently wrote about how they clean splattered bugs off their sensors, but a much grander strategy is needed to let a car deal with failures ...
