Grove - Infrared Reflective Sensor v1.2
Including €0.01 for ecotax
A Grove infrared sensor to detect colour and contrast
The Grove infrared sensor consists of an infrared light emitting diode and a high-sensitivity phototransistor. When the light emitted by the LED encounters an obstacle at a distance measured by the potentiometer, it is reflected back to the phototransistor. Light-coloured objects will generate more current in the phototransistor than an object with dark-coloured surfaces. This IR sensor is a widely used in applications where colour or distance contrast is sharp. The sensor/target distance is calculated based on the time of flight.
Create a line-following robot with the Grove colour sensor
Easy to connect to a Base Shield or a Mega Shield and Arduino compatible, this Grove module is the ideal base for creating a small, line-following mobile robot (for light or dark lines). It can also be used to detect rotary speed. Don’t forget that the sharper the light and/or contrast is, the more effective the sensor will be.
