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, ...

Most proximity sensors use an electromagnetic field to sense the presence of a target metal. But there are times when it's necessary to sense nonmetallic materials such as plastics, liquids, or ...

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.

Proximity detection adds many smart features to the devices we use.For example, when making a call with a phone held to your ear, face detection using proximity sensing can disable the touchscreen and ...

Sponsored by IDT: Thanks to the advances made in inductive position sensing, the technology is carving new paths in automotive design and leaving its optical and capacitive cousins in the dust.

Application characteristics help specifiers choose the best discrete sensor type. Industrial automation systems depend on sensors to detect what is going on with machinery and products for effective ...
