How does a customized infrared beams sensor play the role
In the case of obstacles, the modulated signal sent by the transmitting tube of the customized infrared beams sensor cannot reach the receiving tube smoothly. At this time, the receiving tube cannot receive the signal, and the corresponding internal circuit outputs a high level. When there is no object passing through the customized infrared beams sensor, the modulation signals (light signals) sent by all the transmitting tubes can smoothly reach the corresponding receiving tubes on the other side, so that all the internal circuits output a low level.

Some matters needing attention in the use of the turnstile gate infrared beams sensor
The turnstile gate infrared beams sensor should be kept clean and in good condition during use, especially the spherical emitting part of the front end should not have contaminants such as dirt, nor be damaged by friction, otherwise, the turnstile gate infrared beams sensor will emit The infrared light will produce reflection and scattering phenomenon, which directly affects the transmission of infrared light, which may reduce the sensitivity and remote control distance of the remote control, or may completely fail.

Why does the customized photoelectric beam sensor have no output signal
The first thing that needs to be considered is the problem of customized photoelectric beam sensor wiring and equipment. Regarding the through-beam sensor, the light-emitting part and the light-receiving part need to be used in combination to produce the effect, and both ends need to be powered. The diffuse sensor requires a combination of sensor probes and a retro-reflector. Therefore, it is necessary for the user to provide a stable power supply to the customized photoelectric beam sensor. If the DC power supply is used, the faulty connection of the positive and negative poles will also cause the sensor to have no output signal.
