Ambient Light Sensor - VEML7700 (Qwiic)
Tutti i prezzi sono IVA inclusa
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.
* FiltronTM technology adaption: close to real human eye response
* O-TrimTM 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](https://github.com/sparkfun/SparkFun_VEML7700_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)
