The Gravity: Correlated Color Temperature (CCT) & ALS Meter is a high-performance light sensing device, specifically designed to meet the needs of professional videographers and photographers. With precise calibration, it provides accurate measurements of correlated color temperature and illuminance intensity. It features an illuminance measurement range of 10-10000 Lux with an error margin of ±5 Lux + ±10% Lux and a correlated color temperature measurement range of 2700-6500K with an error margin of ±10% K, ensuring perfect lighting for any shoot. The sensor can be controlled using an Arduino UNO development board, and by following the wiring diagram and sample code provided in the tutorial, the final correlated color temperature, illuminance, and X, Y color coordinates data can be obtained.
Photographers can use the sensor on-site to measure environmental correlated color temperature and illuminance. It ensures that the lighting matches desired color temperature and brightness, resulting in accurate and professional photos and videos. During post-production, photographers rely on the sensor's precise data to adjust image color temperature and brightness, maintaining consistent visual style and optimizing image quality.
Correlated Color Temperature Precise Measurement
Correlated color temperature (CCT) is a critical aspect of lighting, measured in Kelvin (K). It describes the color characteristics of a light source based on blackbody radiation theory. This sensor converts environmental light into standard physical quantities, accurately representing the light temperature of different times of the day and weather conditions. Whether capturing the warm hues of a sunset (2000K-3000K) or the cool tones of a cloudy day (5000K and above), this sensor ensures precise calibration of lighting.
Illuminance Intensity Precise Measurement
Illuminance intensity measures the brightness of a light source in lux (Lux), reflecting the light flux on a unit area. This is crucial for achieving the desired brightness level in photography and videography. The sensor provides precise illuminance readings, allowing for the creation of perfect lighting setups, whether working in a brightly lit outdoor environment or a dimly lit indoor studio.
Compact and Efficient Design, only 26mm×24mm
With a compact size of 26mm×24mm, the sensor is suitable for installations in constrained spaces. It operates efficiently with an operating voltage range of 3.3-5V DC and a low current consumption of 2.8mA, making it ideal for power-sensitive applications

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- lux
- Lux is the standard unit for measuring how much light falls on a surface, similar to how a light meter reports brightness. A sensor that outputs lux gives readings that are easier to compare between rooms, outdoor conditions, and different projects.
- UART
- UART is a simple asynchronous serial interface that sends data over separate transmit and receive wires, usually labelled TX and RX, with both ends set to the same baud rate. It is a common way for microcontrollers and other serial devices to exchange data.
