How to use TCRT5000 infrared sensor?

The working principle of TCRT5000 TCRT5000 is a sensor based on the principle of infrared optical reflection, which contains an infrared light-emitting diode and a photosensitive triode. When working, the infrared light-emitting diode of TCRT5000 continuously emits infrared (invisible light) with a wavelength of 950nm. When the emitted infrared is not reflected back by obstacles or the reflection intensity is insufficient, the photosensitive triode does not work. When the triode receives it, the photosensitive triode is in working condition and provides output. The collector current value Ic of the phototransistor is about 1 mA when it is working. The working...
