Infrared Reflective Sensor Grove

Infrared Reflective Sensor Grove - Infrared Reflective Sensor Grove. The reflectivity of infrared light varies with the color and distance of the reflecting surface. According to this principle, Grove - Infrared Reflective Sensor utilizes a RPR220 reflective photosensor module to detect color and distance. When a light-colored object approaches, the signal intensity received by infrared reflective sensor increases and the indicator LED on board turns red. When a dark-colored object approaches, the intensity decreases and the LED turns off. 

This sensor is a basic and widely used part in applications such as line-following cars, rotary speed detection, auto data logging on utility meters or other situations where color or distance contrast is sharp.

Frequently asked questions about Infrared Reflective Sensor Grove


Q1: What is an Infrared Reflective Sensor Grove?


An Infrared Reflective Sensor Grove is a type of sensor module that can detect the presence or absence of an object in its detection range using infrared light. It consists of an infrared LED (emitter) and an infrared phototransistor (receiver) in a single package. The sensor emits infrared light and measures the reflection intensity to determine the presence or absence of an object.

Q2: How does an Infrared Reflective Sensor Grove work?


The Infrared Reflective Sensor Grove works upon the principle of reflection of infrared light. The sensor emits infrared light, which hits an object in its detection range. If the object is reflective, it will reflect some of the infrared light to the sensor. The phototransistor in the sensor detects the intensity of the reflected light. If the reflected light is above a certain threshold, the sensor considers it the presence of an object. If the reflected light is below the threshold, it considers the absence of an object.

Q3: What are the applications of an Infrared Reflective Sensor Grove?


Infrared Reflective Sensor Grove modules find applications in various fields, including robotics, automation, object detection, and proximity sensing. They can be used in line-following robots, obstacle detection systems, automated machinery, and even as simple object detection sensor in interactive projects.

Q4: How do I connect an Infrared Reflective Sensor Grove to a microcontroller or development board?


The Infrared Reflective Sensor Grove module typically has a Grove connector, which is a universal plug-and-play interface. You can connect it to a compatible microcontroller or development board using a Grove cable. The cable has a 4-pin connector on each end, allowing you to connect the sensor module to the corresponding Grove ports on your microcontroller or development board.

Q5: Can the detection range of an Infrared Reflective Sensor Grove be adjusted?


The detection range of an Infrared Reflective Sensor Grove is generally fixed and depends on the specific model. Some sensors may have adjustable sensitivity using a potentiometer or on board jumper settings. However, in most cases, the detection range is predefined and cannot be dynamically adjusted.

Q6: Are Infrared Reflective Sensor Grove modules affected by ambient light?


A: Infrared Reflective Sensor Grove modules are designed to work in environments with ambient light. They typically use modulation techniques or filters to discriminate between ambient light and the modulated infrared light emitted by the sensor. However, very strong ambient light sources, such as direct sunlight, can still interfere with the sensor's performance and accuracy.
