The Go Direct Light and Color Sensor is a powerful and versatile light sensor that combines the power of multiple sensors to measure light in the visible to ultraviolet electromagnetic spectrum. An RGB color sensor detects relative contributions of primary colors in light.

Visible light sensor: The fast sampling rate for the visible light sensor (1000 Hz) allows you to observe the flicker of fluorescent lamps.

Red, green, blue (RGB) color sensor: Use the RGB sensor to determine the relative contribution of red, green, and blue light. A built-in white LED provides uniform illumination when the sensor is placed directly on a surface, reducing the effect of variable ambient light.

UV sensor: Ideal for experiments using sunlight and UV lamps, the UV sensor responds well to ultraviolet radiation in the UVA and UVB spectrum.

Rechargeable Battery—Ready When You Are: The robust rechargeable battery offers long battery life and provides always-ready operation. Monitor battery life directly from our free Graphical Analysis™ 4 app. Should the battery run low, simply connect the sensor to the charging cable and keep on collecting—no interruptions or inconvenience to you or your students.

Wired or Wireless—The Flexibility to Choose: Our Go Direct sensors connect directly to your mobile device, Chromebook™, or computer using our free Graphical Analysis™ 4 app—no additional equipment or software purchases are necessary. Go Direct sensors can be used wired via USB or wirelessly via Bluetooth® wireless technology, allowing you to choose the solution best for your classroom or laboratory.

The Go Direct Light and Color Sensor can be used in a variety of experiments:

• Explore light intensity as a function of distance
• Conduct polarized filter studies
• Observe the flicker of fluorescent lamps
• Perform reflectivity studies, including color analysis
