Touch-free user interfaces are the new trend for automotive design engineers. There are multiple ways to implement this feature, and one of them is through proximity sensing. Proximity sensing is a ...

Proximity sensors detect objects without physical contact. Most proximity sensors emit an electromagnetic field or beam and look for changes in the field. The object being sensed is called a target.

With increased automation of complex production systems, components that are capable of acquiring and transmitting information regarding the production process become necessary. Proximity sensors -- ...

Now that we have discussed the theory about the sigma-delta modulator, let us design a simple proximity sensor that will detect an approaching hand and switch on an LED. A 0.5 mm 2 wire, 10 cm long, ...
