Marktech had revealed the latest in its line of sensors which combine many LEDs of different wavelengths with a photodiode. MTMD142345PDT38 has five LEDs at 1.04, 1.2, 1.3, 1.46 and 1.55μm, plus an ...

IR sensors rely on an emitter (IR LED) and a detector (photodiode or photoresistor) to measure infrared light and convert it ...

Hamamatsu Photonics introduces a new Photonic Integrated Circuit (Photo IC), P13567-02CT, with applications as an optical moisture detector. This sensor integrates an InGaAs PIN photodiode and a LED ...

This Photodiode based Alarm can be used to give a warning alarm when someone passes through a protected area. The circuit is kept standby through a laser beam or IR beam focused on to the Photodiode.

This circuit uses invisible infrared light to detect the movement of people through the door. A short beep will be generated when the infrared beam breaks. So it is ideal to monitor the passages in ...

Farnell has strengthened its distribution agreement with ams OSRAM, a manufacturer of optical solutions, expanding its portfolio of LEDs, infrared emitters, photodiodes and sensors. Design engineers ...

Linxiao Zhu shows the experimental platform that housed the calorimeter and photodiode. This platform damps vibrations from the room and building, steadily holding the two nanoscale objects 55 ...
