Alessio_Zaino 0:f8a9cceb4186 2 This is a library for the VEML6070 UV-A Sensor
Alessio_Zaino 0:f8a9cceb4186 3
Alessio_Zaino 0:f8a9cceb4186 4 Works with the VEML6070 sensor from Adafruit
Alessio_Zaino 0:f8a9cceb4186 5 ----> https://www.adafruit.com/products/2899
Alessio_Zaino 0:f8a9cceb4186 6 Or knock-off sensors from aliexpress
Alessio_Zaino 0:f8a9cceb4186 7
Alessio_Zaino 0:f8a9cceb4186 8 These sensors use I2C to communicate, 2 pins are required to
Alessio_Zaino 0:f8a9cceb4186 9 interface
Alessio_Zaino 0:f8a9cceb4186 10
Alessio_Zaino 0:f8a9cceb4186 11 The VEML6070 is capable of alerting when UV levels rise past a pre-set level.
Alessio_Zaino 0:f8a9cceb4186 12 It uses a "ACK" pin, and the SMBus Alert Response Address must be read to
Alessio_Zaino 0:f8a9cceb4186 13 clear the alert.
Alessio_Zaino 0:f8a9cceb4186 14 If alert is turned on, you must clear the alert bit before you read/write the
Alessio_Zaino 0:f8a9cceb4186 15 sensor.
