Abstract—Reflective color sensing is typically realized through pho- todiodes with multiple illuminants or photodiodes coated with color filters containing a single illuminant. This paper presents the ...
The reflective properties of plastic make it a notorious offender in this regard. The problem even extends to those objects covered in shrink wrap. Polarizing filters help block false readings from ...
Here is the circuit of a little label sensor ideal for detecting labels on bottles. The circuit offers a peak sensing distance of 2.5 mm (operating range 0.2 mm to 15 mm) backed up by the proven ...
Non-contact EchoPod® and EchoTouch® reflective ultrasonic liquid level sensors feature Flowline’s proprietary Reflective Technology™ that delivers reliable level measurement in condensing environments ...
Today's consumer devices are defined by portability. However, where these designs incorporate movement, how do product engineers integrate feedback? In portable medical applications, reflective ...
The CLI700 reflective object sensor consists of an 880-nm aluminum-gallium-arsenide (AlGaAs) infrared emitter and an npn, buffered, open-collector IC. Both are mounted on a custom, four-leaded TO-72 ...
Capable of effective operation in sunlight with intensities up to 200 kLux, the TCND3000 surface-mount, reflective optical sensor integrates touch and proximity functions and operates with an E909.01 ...
Würth Elektronik has revealed two reflective optical sensors. These are simple devices, with an infra-red emitter and a photo-transistor, both facing upwards, but work at an unusual wavelength. “These ...
