Capacitive touch sensors are based on the electrical capacitance of the human body. When, for example, a finger comes close to the sensor, it creates a capacitance to Earth with a value of 30 to 100 ...

Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, ...

Cambridge Integrated Circuits has introduced a non-contact rotary position sensing IC that can operate at 66,000rpm producing 1,000 quadrature cycles per revolution, or can work at resolutions up to ...

If you need to send data from sensors, there are plenty of options, including a bewildering selection of wireless methods. Trouble is, most of those protocols require a substantial stack of technology ...

[Eiki] found himself in need of a project for his “simple machines” class. Another project had brought him in contact with some relatively cheap MEMS accelerometers and gyroscopes. He had the idea to ...

Controlling sensori-motor systems in higher animals or complex robots is a challenging combinatorial problem, because many sensory signals need to be simultaneously coordinated into a broad ...

There are also sensor-equipped systems that analyze the water on an ongoing basis – according to scientists at the University of South Australia, though, these setups tend to be complex and expensive.

MIT chemists have devised a new way to wirelessly detect hazardous gases and environmental pollutants, using a simple sensor that can be read by a smartphone. With inexpensive sensors, the researchers ...

Secondary sensors help protect feedback control systems from the effects of sensor drift. Feedback control systems manage many parameters within the pharmaceutical industry. They're used in heaters, ...

Here we describe an electronic system that uses a dedicated water-level sensor to switch off the pump motor as soon as the ...
