A typical reflective object sensor consists of an infrared light emitter diode (IRED) and an NPN silicon phototransistor mounted side-by-side on parallel axes in a compact black plastic housing. The ...

Once you have a track and a kart to race on it, what’s missing? A lap counter that can give your lap times in hardcopy, obviously! That’s what led [the_anykey] to create the Arduino-based Lap Timer to ...

What's behind the target can make a tremendous difference in how well reflective sensors do their job. Consider a photoelectric sensor operating in simple diffused mode (i.e., as a proximity sensor).

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 ...

Figure 1a shows a slotted optical switch. An LED is mounted in a plastic housing, facing a phototransistor, but separated by a gap. If something moves into the gap, it blocks the light path between ...

Electronic enthusiasts may be interested in a new open source infrared sensor which has been created to support both Raspberry Pi and Arduino powered projects. The IR Detector proximity sensor has ...

Inductive sensors are non-contact proximity sensors that detect ferrous targets, ideally ones made of mild steel thicker than one millimeter. They consist of four major components: a ferrite core with ...

Leuze has introduced a broad range of stainless steel optical detectors for the food industry. “The devices are designed for reliable operation in wet areas and during intensive cleaning processes and ...
