Description
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.
Application
This sensor is widely used in applications such as:
- Line-following robots
- Rotary speed detection
- Auto-data logging on utility meters or other situations where color or distance contrast is sharp.

What is the difference between the IR distance sensor and the ultrasonic distance sensor?
| IR distance sensor |
Ultrasonic Sensor |
|
| What it does | Measure distance through reflected light waves |
Measure distance through reflected sound waves |
| How it measures | Triangulation: Angle of a reflected IR beam is measured | Time taken between transmitting and receiving sound waves are recorded |
| Human Relationship | Invisible to the naked eye | Unhearable |
| Object Requirements | Suitable to be used to measure complex objects | Not suitable to measure objects with complex surfaces |
What is Grove?
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.
