商品說明

Grove – Infrared Reflective Sensor 紅外線循跡模組 循跡避障模塊  v1.2

紅外線的反射是通過檢測物體表面發射光線的顏色和距離。因此,當一個淺色物體靠近時,信號強度增加,指示燈變成紅色,當深色物體靠近時,信號強度減弱,指示燈熄滅。紅外反射傳感器主要應用在尋線跟跟踪、旋轉測速,或是其他被檢測物體顏色對比強烈的場景。

Grove – Infrared Reflective Sensor v1.2

Grove – Infrared Reflective Sensor v1.2 can be used for detection of proximity and color of objects. The reflective photosensor – RPR220 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 be 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. Black line) at a certain distance.

This sensor is a 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.
