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 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 ...

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.

Silicon-based photodiodes are widely used due to their low cost, low noise, and compatibility with standard IC technologies. However, silicon has a bandgap of 1.12 eV—equivalent to a wavelength of ...

The near-infrared light is a light source with the shortest wavelength, indicated outside of the red color in the light spectrum. The near-infrared light has been widely used in optical communications ...

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 ...

If you are using infrared (IR) hardware in an IoT, embedded, or mobile hardware project and are currently experiencing difficulties debugging IR communications, using one of the circuits shown below ...

A self-powered, wireless-enabled CO2 sensor unit for environment monitoring has been developed by Gas Sensing Solutions (GSS), Sharp and the University of the West of Scotland. The SmartIR NDIR CO2 ...
