    UVC Light Click is a Click board™ with ultraviolet LEDs with 275nm wavelength which can be complemented with UVC Click for measuring exact dose of UV radiation. UVC radiation refers to wavelengths shorter than 280 nm. Because of the spectral sensitivity of DNA, only the UVC region demonstrates significant germicidal properties. As evident by multiple research studies and reports, when biological organisms are exposed to deep UV light in the range of 200 nm to 300 nm it is absorbed by DNA, RNA, and proteins. With two 0.7W (1.4W combined power) UVC Light Click is a perfect solution as a small surface disinfection tool.

    UVC Light Click board™ is supported by a mikroSDK compliant library, which includes functions that simplify software development.

    UVC Light Click board™ includes uses two 0.7W, 275nm LEDs and one green LED that allow users to see approximate area where UVC light is shinning since these UV wavelengths are not visible to human eye and should avoid direct exposure to eye.

    The reason UVC Light Click can be used as desinfection tool is that UV light in the range of 200 nm to 300 nm it is absorbed by DNA, RNA, and proteins. Absorption by proteins can lead to rupture of cell walls and death of the organism. Absorption by DNA or RNA (specifically by thymine bases) is known to cause inactivation of the DNA or RNA double helix strands through the formation of thymine dimers. If enough of these dimers are created in DNA, the DNA replication process is disrupted, and the cell cannot replicate.

    It is widely accepted that it is not necessary to kill pathogens with UV light, but rather apply enough UV light to prevent the organism from replicating. The UV doses required to prevent replication are orders of magnitude lower than required to kill, making the cost of UV treatment to prevent infection commercially viable.

    UVC Light Click is implementing TPS61169 LED driver with PWM brightness control to drive LEDs in series and MC34671 battery charger to allow charging of battery when Click board™ is inserted in mikroBUS™ socket, CHG LED will indicate the charging in progress and will turn off once the battery charging is finished. When PWR SEL jumper is repositioned to the right position you can use UVC Light Click standalone if no dimming is necessary or high mobility is needed.
