Frequently Asked Questions

Q: Is the VEML7700 sensor module compatible with Raspberry Pi?

A: Yes! The VEML7700 ambient light sensor module uses the I2C (IIC) Gravity interface and supports both 3.3V and 5V power, making it fully compatible with Raspberry Pi, Arduino, and most other common microcontroller platforms. Simply connect via the I2C bus and start reading lux values immediately.

Q: What is the detection range of the VEML7700 sensor?

A: The VEML7700 sensor module measures ambient light from 0 lx (complete darkness) up to 120,000 lx (bright direct sunlight), with a high resolution of 0.0036 lx/ct. This makes it one of the widest-range, most accurate ambient light sensors available for DIY and industrial projects.

Q: Does this sensor support low-power operation?

A: Absolutely. The VEML7700 module draws only 45µA during normal operation and drops to just 0.5µA in shutdown mode, making it highly suitable for battery-operated and energy-efficient IoT devices.

Q: What does the package include?

A: Each order includes 1 × VEML7700 Ambient Light Sensor Module (16.5 × 16.5 mm). No batteries are required. Please note that the actual product color may vary slightly from images due to monitor display differences, and minor measurement tolerances apply.
