• Analog sensors
• Uses PH 2.0 socket
• Special sensor with Arduino expansion boards

The DFRobot Grayscale Sensor is an analog sensor. It is a special sensor with arduino expansion boards. The Gray-scale sensor interface uses PH 2.0 socket. The power supply needs the same controller, typically for 3.3V or 5V. The definition of gray-scale sensor pin is (1) output (2) complex (3) power.
