DFRobot Gravity Factory Calibrated Correlated Color Temperature CCT & ALS Meter for Professional Photography
The DFRobot Gravity CCT & ALS Meter is a factory-calibrated sensor module for precise measurement of Correlated Color Temperature (2700K-6500K) and ambient illuminance (10-10,000 Lux). It communicates via I2C or UART and is compatible with 3.3V/5V logic systems including Arduino, Raspberry Pi, and ESP32, making it ideal for professional lighting control and photography applications.
Features
- High-precision measurement of Correlated Color Temperature (CCT) from 2700K to 6500K with ±10% accuracy.
- Accurate ambient light sensing (ALS) across a 10 to 10,000 Lux range with low error margin (±5 Lux + ±10%).
- Dual communication interface supporting both I2C and UART protocols for flexible system integration.
- Low-power operation at 2.8mA, compatible with 3.3V to 5V DC power supplies.
- Compact form factor (26mm x 24mm) designed for installation in space-constrained environments.

The DFRobot Gravity CCT & ALS Meter integrates a high-performance spectral sensor and a dedicated signal conditioning circuit to deliver factory-calibrated readings of Correlated Color Temperature (CCT) and Ambient Light Sensor (ALS) illuminance. This eliminates the need for user calibration and ensures measurement consistency from unit to unit. The sensor’s digital output provides stable, noise-resistant data via I2C or selectable UART communication.
Engineered for professional environments, the module operates reliably within an industrial temperature range of -10°C to 60°C. Its precision is critical for applications requiring strict adherence to lighting standards, such as color grading in photography and videography, or maintaining consistent ambient conditions in galleries and studios. The module’s Gravity-series 3-pin interface simplifies connection to a wide range of microcontrollers and single-board computers.
