Measure your beam as never before with the NanoScan™ beam profiler The advantage of scanning slit beam profiling is submicron precision for measuring beam position and size Scan head configurations include Silicon Germanium and Pyroelectric versions for a wide range of wavelengths and laser power levels The NanoScan software is available in two versions.
Arduino IR Breakbeam Sensors Adafruit Learning System
By the late 1930s several radio manufacturers offered remote controls for some of their higherend models Most of these were connected to the set being controlled by wires but the Philco Mystery Control (1939) was a batteryoperated lowfrequency radio transmitter thus making it the first wireless remote control for a consumer electronics device Using pulsecount.
Passive infrared sensor Wikipedia
IR sensor the main concept of IR sensor is to produce a beam of infrared light (whose wave wavelength is longer than visible rays and shorter than microwaves in normal infrared wave length should be greater than 6µm) IR sensors are based on three different laws they are planks radiation law Stephan Boltzmann law and Wien’s displacement law Planks.

Infra red rays reflected from a static object will be in one phase and the rays reflected from a moving object will be in another phase The circuit uses this principle to sense the motion The IC1 (NE 555) is wired as an astable multivibrator The IR diode connected at the output of this IC produces infrared beams of frequency 5Khz These beams are picked by the infrared sensor.
