DFRobot Gravity Analog Grayscale Sensor V2 - 3.3V-5V Analog Output
The DFRobot Gravity Analog Grayscale Sensor V2 is a calibrated light intensity sensor compatible with Arduino, Raspberry Pi, and other 3.3V/5V microcontrollers. It outputs an analog voltage proportional to reflected light intensity, enabling precise grayscale measurement from black to white.
Features
- 3.3V to 5.5V wide operating voltage range for flexible system integration
- Analog voltage output for direct ADC reading and precise grayscale intensity measurement
- Integrated white LED provides consistent reflective illumination for stable readings
- Standard Gravity 3-pin interface with analog (‘A’) port marking for plug-and-play use
- Compact PCB design (30mm x 22mm) with mounting holes for easy installation

The DFRobot Gravity Analog Grayscale Sensor V2 utilizes a photoconductive cell (LDR) paired with a dedicated white LED to measure surface reflectivity. The onboard LED provides a controlled light source, ensuring consistent illumination independent of ambient conditions. The sensor’s resistance changes in response to the intensity of reflected light, which is converted into a proportional analog voltage signal for microcontroller processing.
Designed for reliability, the sensor features an immersion gold PCB finish for corrosion resistance and a robust connector for extended lifecycle. Its output is linear across a grayscale spectrum, making it ideal for applications requiring differentiation between light and dark surfaces or monitoring light level transitions.
