Looking for a Qwiic sensor that can measure the ambient light level directly in lux? This is it!

The VEML7700 is a high accuracy, 16-bit resolution, digital ambient light sensor in a miniature transparent 6.8 mm x 3.0 mm x 2.5 mm package. It includes a high sensitivity photodiode, a low noise amplifier, a 16-bit A/D converter and supports an easy to use I²C bus communication interface.

• Filtron^TM technology adaption: close to real human eye response
• O-Trim^TM technology adoption: ALS output tolerance ≤ 10 %
• 16-bit dynamic range for ambient light detection from 0 lx to about 167 klx with resolution down to 0.005 lx/count
• 100 Hz and 120 Hz flicker noise rejection
• Excellent temperature compensation
• High dynamic detection resolution
• Software shutdown mode control
• High and low threshold windows with interrupt flags

Our Arduino Library converts the raw sensor data into lux, automatically compensating for the sensor's gain and integration time settings.

As usual, our breakout board includes:

• Two Qwiic connectors
• I²C breakout pins
• I²C pull-up resistors (configurable)
• Power LED (configurable)
