This is a highly accurate sensor that is calibrated to detect the PPM of Alcohol present in the environment; however, to do so, you must first understand the sensitivity characteristics of the MQ-3 Sensor, which can be found in theMQ3 Sensordatasheetand look like the image below. In the ...
A state-of-the-art interferometer can measure distances to within 1 nanometer (one billionth of a meter, which is about the width of 10 hydrogen atoms), but like any other kind of measurement, it's subject to errors. The biggest source of error is likely to come from changes in the wa...
What is a hologram and how does it work? Laser beams are split up in order to construct a hologram, causing the light waves that make up the two parts of the beam to travel in similar fashion. It is due to this that the image seems to change. This is also what lends holograms thei...
