Frequently Asked Questions

What is the operating voltage range for this VEML7700 module?

The module operates from a 3.3V or 5V DC power supply. It includes an onboard voltage regulator that provides a stable 3.3V supply to the sensor IC and can also supply up to 100mA to external components.

How do I communicate with the sensor, and what is its I2C address?

Communication is via the standard I2C serial interface. The sensor has a fixed I2C slave address of 0x10. You can read lux data and configure gain/integration time settings through the register map defined in the VEML7700 datasheet.

What is the typical accuracy and response time of this sensor?

The VEML7700 provides high-resolution output with 0.0036 lux per count. Its accuracy is optimized across the full 0-120k lux range with excellent linearity. The digital output provides fast reading updates, with response time dependent on the configured integration time setting.

Is this sensor suitable for outdoor sunlight measurement?

Yes, the sensor's wide measurement range up to 120,000 lux covers typical outdoor ambient light conditions, including indirect sunlight. For direct sun measurement, ensure the sensor's angular response and potential saturation at peak intensities are considered in your application.
