UV 2 click is a mikroBUS™ add-on board with a VEML6075 UVA and UVB light sensor. VEML6075 is a CMOS chip that incorporates a photodiode, amplifiers, and analog/digital circuits.
With UV 2 click, Solar ultraviolet light intensity is converted to 16-bit digital values. UVA and UVB are in separate channels. To keep a stable output in changing temperature conditions, the chip has temperature compensation capabilities. This ensures reliable performance under long term UV exposure.
The sensor has a specified UVA sensitivity of 365 nm and UVB sensitivity of 315 nm
The board communicates with the target MCU through the mikroBUS™ I2C interface. Designed to use a 3.3 power supply only. |

Design devices that warn you of excesive ultraviolet radiation levels with UV click. This click boards carries the ML8511 IC that is sensitive to UV-A (365-315 nm) and UV-B (315-280 nm) rays. The board can output either analog or digital signals proportional to the amount of UV exposure. To bypass the onboard MCP3201 ADC and get an analog output, solder the A/D SEL jumper in the AN position. Depending on the position of the jumper, UV click communicates with the target board either through mikroBUS SPI (CS, SCK, MISO) or AN lines; additionally, the sensor can be enabled or disabled from the MCU through the RST (EN) pin. When handling UV click, be careful not to press or rub the sensitive surface of the ML8511 sensor IC. UV click uses a 3.3V power supply only. |
