E18-D80NK Infrared Avoidance Sensor Close To Switch Smart Car 3-80cm With Dupont Head

   This is an integrated photoelectric sensor receiving and receiving integrated.The detection distance can be adjusted according to requirements.The sensor has a detection

   The characteristics of long distance, small interference from visible light, low price, easy assembly, easy to use, etc., can be widely used in robot avoidance, (but this infrared sensor probe is not suitable for use in natural lighting environments, because natural light contains infrared. Friends who need to use infrared probes, please pay attention to this problem. It can still be used in an infrared environment without infrared enviro)

Many automated products such as as as running line counters.

Common questions about sensors answer:

1. Q: Is this a digital sensor or analog sensor?

  Answer: This is a digital sensor, NPN normally on photoelectric switch; the output status is 0, 1, that is, the low level and high level in the digital circuit, the high level is output in the normal state, and the target output low level is detected.

2. Q: Can I connect to the IO port of the single-chip microcomputer?

  Answer: It can be directly connected to the IO port of the single-chip microcomputer.

3. Q: What is the resistance value if you add a pull resistance?

  Answer: Plus the pull resistance value is generally about 10K;

4. Q: Why does the indicator light keep on after connecting to the power supply?

  Answer: First of all, ensure that the power supply is stable 5V ±2%, and secondly, the probe output terminal cannot be connected to the single-chip microcomputer output port;

5. Q: Why after connecting to the infrared switch power supply, the indicator light keeps on?

  Answer: 1. Please check whether the power supply is connected reversely, that is, the infrared output is connected to the positive power supply; 2. Please check whether there are any obstacles in the direction detection range of the probe to facing the open direction.

6. Question: Is the instruction manual too simple?

  Answer: This is a photoelectric switch, only three wires, power supply
