Description
Product Overview
The VEML7700 based Ambient Light Sensor Module from GODIYMODULES is engineered to provide high‑resolution lux measurements across a wide range of lighting conditions. Measuring from 0 to 120000 lux with 16‑bit precision, the module captures subtle changes in illumination that are critical for scientific instrumentation, industrial control systems, and advanced hobbyist projects. The sensor is housed in a compact plastic enclosure measuring 4.76 x 4.02 x 1.22 inches and weighing only 0.32 ounces, making it easy to mount on any printed circuit board. Power requirements are flexible, accepting either 3.3 V or 5 V DC, and communication is handled through a standard I2C interface at address 0x10, which cannot be altered. The included five‑pin connector must be soldered to the board, providing a reliable mechanical and electrical link.
Usage
This module excels in environments where accurate light measurement is essential. In laboratory settings, it can be integrated into photometers to monitor reaction chambers, growth incubators, or optical experiments. Industrial applications include monitoring illumination levels on production lines, controlling lighting in smart factories, and providing feedback for energy‑saving systems. Hobbyists and makers will find the module valuable for DIY weather stations, automated plant grow lights, and robotics that respond to ambient light. Because the I2C bus allows multiple devices to share the same communication lines, the sensor can be combined with temperature, humidity, or motion sensors to create comprehensive environmental monitoring solutions.

FAQ
What is the I2C address of the sensor?
The module uses a fixed I2C address of 0x10, which cannot be changed. This simplifies software configuration when multiple I2C devices are present.
Can the module operate on both 3.3 V and 5 V power supplies?
Yes, the sensor is designed to accept either 3.3 volts or 5 volts DC, giving flexibility for different system designs and power budgets.
Do I need to calibrate the sensor before use?
The VEML7700 chip is factory calibrated for standard lighting conditions. For highly specialized applications, users may perform additional calibration against a known reference source.
Is the five‑pin connector optional?
The connector must be soldered to the PCB to provide power and I2C communication. It is included with the module to ensure a reliable mechanical and electrical connection.
What is the typical response time of the sensor?
The sensor provides updated lux readings at a rate of up to 10 samples per second, which is sufficient for most monitoring and control applications.
