A new optical emitter/phototransistor pair designated the OPB100 features a dc drive current and variable distance sensing up to 1 m.

Designed to receive IR pulses from an emitter with a peak wavelength of 940 nm, the sensor module operates at a supply voltage range from 2.5 V to 5.5 V, features a low supply current of 0.7 mA ...

Schematic of IR Beam Breaker Circuit TSOP1738 IR sensor module responds to only 38 kHz pulsed infrared rays. It will not sense continuous IR ray from the IR LED. So a transmitter circuit (as one in TV ...

The IR sensor array, which on the palm-sized vehicle consisted of just a handful of components, evolved into a PCB-backed bar nearly 0.5 meters wide. Potentiometer tuning was a fiddly affair, but ...

Vishay Intertechnology has introduced an extended temperature "E" option for its TSSP77038 infrared (IR) sensor module in the Heimdall package. Designed to meet the requirements of outdoor ...

Unlike high sensitivity fixed-gain IR sensor modules that require attenuators like dark panels, apertures, and sunshades to protect them against sunlight — adding to overall solutions costs ...

Lextar Electronics has released PR88M32, an infrared (IR) LED biometric sensor module that it says can recognize human faces and iris. With a thickness of 1.4mm, the sensor module is expected to ...

The proximity sensing is one of the bare basic feature of any smartphone, but the IR sensor module leaves a ugly dark spot on the front of the phone – something that the ultrasonic sensor won ...
