APPLICATION INFORMATION
Special care must be taken into consideration when handling the VEML6031X00. VEML6031X00 is sensitive to dust and
scratches, proper optical device handling procedures are recommended.
The optical surface of the device must be kept clean for optimal performance in both prototyping with the device and mass
production manufacturing procedures. Tweezers with plastic or rubber contact surfaces are recommended to avoid scratches
on the optical surface. Avoid manipulation with metal tools when possible. The optical surface must be kept clean of fingerprints,
dust, and other optical-inhibiting contaminants.
If the device optical surface requires cleaning, the use of isopropyl alcohol is recommended. A few gentle brushes with a soft
swab are appropriate. Avoid potentially abrasive cleaning and manipulating tools and excessive force that can scratch the
optical surface.
If the VEML6031X00 performs less than optimally, inspect the optical surface for dirt, scratches, or other optical artifacts.
VEML6031X00 is a cost effective solution of ambient light sensor with I2C bus interface. The standard serial digital interface is
easy to access “Ambient Light Signal” without complex calculation and programming by external controller. Beside the digital
output also a flexible programmable interrupt pin is available.

Notes
•
The interrupt pin is an open drain output. Proposed values for the pull-up resistors should be > 1 kΩ, e.g. 2.2 kΩ to 4.7 kΩ for the R1 and
R2 (at SDA and SCL) and 10 kΩ to 100 kΩ for R3 (at interrupt).
Normally just one decoupling capacitor is needed. This should be ≥ 100 nF and placed close to the VDD pin.
For detailed description about set-up and use of the interrupt as well as more application related information see AN: “Designing
VEML6031X00 into an Application”

2. I2C Interface
The VEML6031X00 has eighteen register addresses responsible for operation control, parameter setup and result buffering.
All registers are accessible via I2C communication. Fig. 9 shows the basic I2C communication with VEML6031X00.
The built in I2C interface is compatible with I2C modes “standard” and “fast”: 10 kHz to 400 kHz.
Please refer to the I2C specification from NXP for details.

Device Address
Register Addresses
The VEML6031X00 is available in two different
pre-configured slave addresses.
The VEML6031X00 has eighteen registers, accessible
through there respective 8-bit command codes.
For one version the predefined 7 bit I2C bus address is set
to 0101001 = 0x29. The least significant bit (LSB) defines
read or write mode. Accordingly the bus address is set to
0101 0010 = 0x52 for write and 0101 0011 = 0x53 for read.
The second version comes with predefined 7 bit I2C bus
address of 0010000 = 0x10, so, here the write address is
0010 0000 = 0x20 for write and 0010 0001 = 0x21 for read.
The registers are 0x00 to 0x17 (0x02 and 0x03, 0x08 to 0x0F
and 0x16 are not defined / reserved). Note that due to the
location of the two shutdown bits (SD and ALS_IR_SD), one
in register 0x00 and the other in 0x01, it is necessary to
always write to both registers at once when configuring the
device.
Auto-Memorization
The VEML6031X00 stores the last measured ambient data
before the device is shutdown, keeping the data accessible.
When VEML6031X00 is in shutdown mode, the host can
freely read this data via read command directly.

CALCULATING THE LUX LEVEL
Command code 0x10 and 0x11 contain the results of the
ALS measurement. This 16-bit code needs to be converted
to a decimal value to determine the corresponding lux value.
The calculation of the corresponding lux level is dependent
on the programmed gain setting and the chosen integration
time.
Every time the integration time is halved, the resolution is
doubled but also the possible detection range is doubled.
The same principle is valid for the gain setting. For
ALS_GAIN = x1 it is doubled. For PD_DIV4 = 1/4 the size of
the photodiode is just 1/4, so, also the sensitivity is just 1/4,
resolution and max. possible detection range is times 4, to
allow for higher illuminations up to about 228 klx.
The component is most sensitive with ALS_GAIN = x2,
PD_DIV4 = 4/4 and an integration time of 400 ms, specified
to 0.0034 lx/step.

Note
(1)
For integration time of 3.125 ms the maximum count level is no longer 16 bit, so, half the integration time no longer leads to double the
max. lux level
Example:
If the 16-bit word of the ALS data shows: 0000 0101 1100 1000 = 1480 (dec.), the programmed ALS_GAIN = x1, PD_DIV4 = 4/4
(= x1) and ALS_IT = 100 ms, the corresponding lux level is: light level (lx) = 1480 x 0.0272 = 40.256 lx.
