NGW-1pc Grove - Infrared Reflective Sensor v1.2
- Features
- Highly sensitive and reliable: With the help of the reflective photosensor - RPR-220, There is a built-in visible light filter minimizes the influence of stray light and a plastic lens is used for high sensitivity.
- Adjustable sensitivity for different occasions: The sensitivity of the reflective light sensor can be changed by adjusting the potentiometer with a screwdriver.
- Grove unified socket: The sensor ensures "Plug and Play" and could be versatile for various applications.

Description
Grove - Infrared Reflective Sensor is used to detect the presence of an object within a specific range. This product uses the RPR-220 to detect. The sensor consists of an IR LED and a photosensor (phototransistor) pair. The light emitted by the IR LED gets reflected by any object placed in front of the sensor and this reflection is detected by the photosensor (phototransistor). Any white (or lighter) colored surface reflects more than black (or darker) colored surface.
When the reflected light is detected, it produces Digital LOW (or Binary 0) output on the SIG pin. The on-board LED indicator will also glow. If no reflection is detected or if the object is too far from the sensor, the output on the SIG pin stays at Digital High (Binary 1). The on-board LED indicator will be off as well. The detectable range of this sensor is 416 mm. The module incorporates a Rail-to-Rail Operational Amplifier to amplify the output of phototransistor. There is a potentiometer which can be used to adjust the gain of the amplifier, that is, sensitivity of detection.
