BEAM robotics, which stands for Biology, Electronics, Aesthetics, and Mechanics, is an ethos that focuses on building robots with simple analog circuits. [NanoRobotGeek] built a great example of th… ...

Schematic of IR Beam Breaker Circuit. TSOP1738 IR sensor module responds to only 38 kHz pulsed infrared rays. It will not sense continuous IR ray from the IR LED. So a transmitter circuit(as one in TV ...

PIR LED Security Light Circuit Schematic. Notes. The PIR sensor requires an initial stabilization time of about 10 to 60 seconds in order to function properly. During this time, the sensor gets ...

Automation light grids take many forms and cover applications from simple to complex. Sizes range from a few inches to several feet, and resolutions from 2 to 100 mm. Nearly every sensor ...

The sensor in this application, a BPW21R photocell (from Vishay), is used to generate photocurrent proportional to the ambient light intensity (see the figure).

A surprising trick that allows a beam of light to be completely absorbed even in the thinnest of layers: Using mirrors and lenses, a 'light trap' can be constructed, in which the light beam is ...
