Grove - Infrared Reflective Sensor v1.2 can be used for the detection of proximity and color of objects. The reflective photosensor - RPR-220 used in this module consists of an infrared light emitting diode and a high –sensitivity phototransistor. Light-colored objects directly in front of the sensor will reflect more infrared light as well as generate more current in the phototransistor than an object with dark-colored surfaces, this can tell from a built-in indicator LED which will turn red with sufficient flow of current. Also, the intensity of the reflective light increases as the object getting closer. You can adjust the potential-meter on the back of the board if you want to detect a specific object (eg. Blackline) at a certain distance.
This sensor is widely used in applications such as:
Panel-mounting Grove interface
Digital output: 0 or VCC
Built-in indicator LED
Threshold adjustable via potentiometer
Power supply: 3.5 – 5.5V DC
Reflective Photosensor: RPR-220
Effective working distance: 4-15mm
Minimum detectable width for monochrome lines: 10mm
Connector: 4 pin Buckled Grove interface
Measure distance through reflected sound waves
Grove makes it easier to connect, experiment, and simplify the prototyping process. No jumpers or soldering required. We have developed more than 300 Grove modules, covering a wide range of applications that can fulfill a variety of needs. Not only are these open hardware, but we also have open-source software.

Hi there~ Unfortunately, this sensor can only measure distance.Regards.Color is out of his range. Regards
Hi there~ It can work with 3.3V system. Regards
