商品描述
側視紅外線發射器和紅外線接收器。這些簡單的設備在 940nm 下運作，適用於包括遠程控制和非接觸式物體感應在內的通用紅外線系統。在任何微控制器上使用簡單的 ADC 都可以從檢測器收集可變讀數。與任何 LED 設備一樣，發射器通過限流電阻驅動至高達 50mA。檢測器是一個 NPN 晶體管，由入射的紅外線光偏置。
Description:
Side-looking Infrared Emitters and IR Detectors. These simple devices operate at 940nm and work well for generic IR systems including remote control and touch-less object sensing. Using a simple ADC on any microcontroller will allow variable readings to be collected from the detector. The emitter is driven up to 50mA with a current limiting resistor as with any LED device. The detect is a NPN transistor that is biased by incoming IR light.
