Various types of Light Sensors are available in the market. One of the most common type & cost effective type of Light sensor is a Light Dependent Resistor abbreviated as LDR. A LDR is also called as photo resistor or photocell. It is basically a variable resistor whose resistance varies according to the light intensity falling on it. The resistance of the LDR can be few Mega Ohm’s (M?) in dark conditions, and in Light condition the resistance can be of several hundred ohm’s.
Using fiber optic cables as waveguides for transmitting light that is ultimately converted into voice calls or data has been a mainstay for the telecommunications industry for decades.
Turck's TB-Q08 RFID read/write head measures just 32 x 20 x 8 mm with integrated antenna, electronics and two LEDs visible from all directions.
Researchers at Princeton University have observed a bizarre behavior in a strange new crystal that could hold the key for future electronic technologies. Unlike most materials in which electrons travel on the surface, in these new materials the electrons sink into the depths of the crystal through special conductive channels.
According to a post by Edward Aten, we would spend a total of 3.5 days untangling headphones over the course of our life. No wonder why Apple is looking to kill the headphones in its future phones.Aten decided to do the math to see how much time is wasted when we endlessly try to untangle our headphones. So, what did he do to arrive on that number?
From pacemakers to insulin pumps, electronic implants are a powerful medical tool, but they present their own suite of risks — scarring, rejection and sepsis among them. Now a team of researchers has createda dissolving electronic implant, sort of like a much more sophisticated version of dissolving sutures. Sutures, however, can’t be injected into a rat’s brain, and don’t come equipped with temporary Wi-Fi.
