BAE Systems’s Adaptiv technology enables objects as big as tanks to completely vanish from view–when seen at night with an infrared sensor ... s BAE’s own e-ink-based concept, as well ...

That’s what led [the_anykey] to create the Arduino-based ... sensor module (a Velleman PEM10D) to detect when a kart passes by. This module is similar to a scaled-up IR reflective object ...

But the circuit in the figure shows an infrared close-object alert system built aroun Many robotic applications require a sensor to detect ... a transistor- based relay switcher can be driven ...
