What is the difference between UVA,UVB,UVC and UVV



How does UV disinfection lamp work?
When it comes to UV sterilization, not all kinds of UV are effective. only UVC (100-
280nm) has high enough energy to effectively kill microorganisms. When you are
shopping for a UV sterilization product to try in your home or business, make sure
that its UV wavelength falls in the range of UVC (100-280 nm).Is UV sterilization
effective for viruses and bacteria? The short answer is yes, and even more organisms.
Studies have shown that UVC at 254 nm is effective against all foodborne pathogens,
natural microbiota, molds, and yeasts. Because microorganisms come with different
sizes and shapes that affect their UV absorption, the required time for killing each
species varies.2How does UV sterilize something? I’m glad you asked! UV
sterilization also known as UV disinfection or ultraviolet germicidal irradiation (UVGI)
works by breaking down certain chemical bonds and scrambling the structure of DNA,
RNA and proteins, causing a microorganism to be unable to multiply. When a
microorganism is unable to multiply, it is considered dead since it cannot reproduce
within a host and is no longer infectious.“Dead.” That sounds perfect. How much
time does it take to get this nasty stuff to said “dead” status? Let’s talk destruction
specifics. Since UV sterilization uses the energy of UVC to destroy biomolecules, its
effectiveness depends on the total energy applied which is affected by the length of
exposure time and the distance from the light source. For example, if you use a UV
lamp held within 1 inch above a petri dish grown with E. coli, it will only take 1-2 min
to show a complete sterilization.1 For sterilizing surgical instruments in a medium UV
box, it might take 5-10 min. For sterilizing an 8-foot biosafety cabinet in a lab, a
common recommendation is 30 min.







How PIRs Work

 

PIR sensors are more complicated than many of the other sensors explained in these tutorials (like photocells, FSRs and tilt switches) because there are multiple variables that affect the sensors input and output. To begin explaining how a basic sensor works, we'll use this rather nice diagram

The PIR sensor itself has two slots in it, each slot is made of a special material that is sensitive to IR. The lens used here is not really doing much and so we see that the two slots can 'see' out past some distance (basically the sensitivity of the sensor). When the sensor is idle, both slots detect the same amount of IR, the ambient amount radiated from the room or walls or outdoors. When a warm body like a human or animal passes by, it first intercepts one half of the PIR sensor, which causes a positive differential change between the two halves. When the warm body leaves the sensing area, the reverse happens, whereby the sensor generates a negative differential change. These change pulses are what is detected.
