TCRT5000 infrared sensor emits infrared discharging diode continually when no infrared rays released or showed back is shown back however the strength is not big enough, the phototransistor has actually been in the off state, and the output terminal of the module is high, suggesting that the diode has remained in the off state; in the things to be found within the detection range, and the strength of the reflected infrared rays is big enough, phototransistor saturated, and the output terminal of the module is low, the sign LED is lit.
