Availability date:
This sensor is not like its competitor. Based on the the Vishay VEML6075 sensor chip, it have 2 measurement channels for UVA & UVB with 16-bit resolution.
This sensor converts the Sun UV light intensity to digital data read over the I2C bus and offers an accurate measure of internal signal strength.
The VEML6075 UV sensor provides reliable UV radiation measurement under long time solar UV exposure. The reliability is possible thanks to the excellent temperature compensation capability of the sensor (-40°C to +85°C). VEML6075 is a low power consumption sensor with a minimum power as low as 800nA in shut-down mode.
As it operates in a voltage ranges from 3.3V to 5V, it can be used with Arduino, Raspberry-Pi, Pyboard, PYBStick to create portable electronic product, wearable device, weather station, flame detecting, etc.
DFRobot offers Arduino a Python library while MC Hobby offers the MicroPython driver for this sensor.
Thanks to the gravity connector (PH2.0-4P) and its I2C wiring gravity cable (4wires), this sensor is quite easy to plug onto the Gravity/Boson EcoSystem or onto the breadboard (thank to the awesome 2.54mm female connector on the cable).
The ultraviolet section of the electromagnetic spectrum extends from 400 nm to 100 nm, just below the X-ray section of the spectrum. The Ultraviolet range is divided in 3 sub-ranges:
The UV-C measurement is discussed in this MCHobby Forum thread.
