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 ...
Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level sensing ...
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, ...
I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...
CAMARILLO, Calif.--(BUSINESS WIRE)--Semtech Corporation. (Nasdaq: SMTC), a leading supplier of analog and mixed-signal semiconductors, today announced the SX9300, an ultra-low power capacitive ...
Two tiny ICs and a few passive components can yield a capacitive proximity sensor with excellent sensitivity and extremely fast response time. The circuit’s operation leverages the pulse-front-edge ...
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.
CARLO GAVAZZI is proud to announce the launch of their new 4th Generation TRIPLESHIELD CA18CA Capacitive Proximity Sensors. In addition to greatly improved immunity to dust, humidity, and ...
Carlo Gavazzi is excited to introduce three new series of M12 Capacitive Sensors with IO-Link Communications. Based on our 4th generation TRIPLESHIELDTM sensors, these CA12 Series Sensors represent ...
