High Precision VEML7700 I2C 0-120Klx Ambient Light Sensor Module for Arduino Raspberry Pi ESP32 PIR Motion Sensor for Smart Home

Product Details

Key Features and Benefits:Human Eye Spectral Response: Designed to match the sensitivity of the human eye. Provides natural-feeling and accurate light intensity readings, making it perfect for automatic brightness adjustment on screens, tablets, and human-centric smart lighting systems
Extreme Accuracy and Wide Range: Measures an incredible range from 0 to 120,000 lux with high resolution (0.0036 lux/step). Faithfully captures light from a moonlit night to bright sunlight, enabling truly responsive environmental adaptationI2C Plug-and-Play Interface: Simple I2C communication (address 0x10). The built-in 3.3V LDO regulator and level shifter enable safe operation with 3.3V and 5V microcontrollers (such as Arduino Uno, ESP32, Raspberry Pi) without additional components
Flexible integration: The ultra-compact board comes with optional solder-on headers, allowing you to choose the mounting style that best suits your project—demo board, printed circuit board (PCB), or direct wiringProduct description
The VEML7700 is not just another light sensor; it is a premium photometric sensor designed for applications where accuracy matching human perception is critical. Integrate it into your projects to build devices that intelligently adjust their behavior based on ambient light—think self-dimming displays, adaptive room lighting, or environmental data loggers
[Assembly required]: Pin headers are included but not pre-soldered. Basic soldering skills are required to assemble it I2C Address and Library: The default I2C address is 0x10. You will need to use the dedicated VEML7700 library in the Arduino IDE or other platform for easy data reading. Example code is widely available online Understanding Lux and Application: This sensor measures illuminance (lux), which is light as perceived by humans, not raw radiometric power. It is ideal for human-centered controls but may not be suitable for plant growth lighting or pure energy measurements Avoid direct contamination: The sensor surface is sensitive. Avoid touching the white sensing area and keep it free from dust, grease or scratches for accurate readingsSpecifications:Sensor IC: VEML7700, Output: Measurement range: 0 lux to 120,000 luxResolution: 0.0036 lx/stepInterface: I2C (standard, address 0x10)Supply voltage (VIN): 2.5V to 3.6V (built-in 3.3V LDO)Logic voltage: 3.3V (5V-resistant I/O with level adapter)Operating temperature: -40°C to +85°CMounting: 4 M2 mounting holesPackage includes1 x VEML7700 Ambient Light Sensor Module (PCB)1 x 4-pin male header (solderable)
