PRODUCT DETAILS

Grove - IR Distance Interrupter is used to detect any object blocking the path of light, which is based on ITR9909.

Features

  • Highly sensitive and reliable: With the support of ITR9909 reflective photosensor, when the reflected light is detected, the high level can be quickly output.
  • Longer detectable distance: Up to 40cm, make users more comfortable to use.
  • Adjustable sensitivity for various occasions: The sensitivity of the sensor can be changed by simply adjusting the potentiometer with a screwdriver.
  • More durable: No fear of easy damage.
  • Grove unified socket: The sensor ensures "Plug and Play" and could be versatile for various applications.

Description

Grove - IR Distance Interrupter is used to detect any object blocking the path of light, which is based on ITR9909. The ITR9909 consist of an infrared emitting diode and an NPN silicon phototransistor, encased side-by-side on converging optical axis in a black thermoplastic housing, The phototransistor receives radiation from the IR only. This is the normal situation. But when an object is in between, phototransistor could not receive the radiation. Any white (or lighter) colored surface reflects more than black (or darker) colored surface.

When the reflected light is detected, it produces Digital HIGH (or Binary 1) 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 LOW (Binary 0). The on-board LED indicator will be off as well. The detectable range of this sensor is 7.5–40 cm. 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.

Note

This product is mildly sensitive to non-IR radiations also and hence any bright light on photosensor impairs or disturbs IR light detection.

    great, but sunlight is a significant interference This is great, but even at minimum sensitivity, I can't use it near windows during the daytime.
