Using pulsed light enables the sensor to distinguish the reflection from the ambient infrared environment. However, do not put it too close to a strong source of infrared radiation because if the ...

Now we can stepped into the light with our favorite microcontroller Arduino! Since a vast number of analog/digital ambient light sensors/light sensor modules are now available at reasonable price, ...

He suspected EMF interference so as a quick first step he decided to throw together an EMF detector using an Arduino. It uses a bank of LEDs as an indicator bar to reflect the EMF picked up by the ...

The additional sensors include a nine-axis Inertial Measurement Unit, as well as temperature, pressure, humidity, light, color, and gestures sensors.

Ambient light sensors can reveal your device activity. How big a threat is it? For now, there's no reason for concern, but that could change in coming years.
