Answers to common questions about sensors:
1. Question: Is this a digital sensor or an analog sensor?
Answer: This is a digital sensor, NPN normally open photoelectric switch, the output state is 0,1, that is, the low level and high level in the digital circuit, the normal state outputs high level, and the target output low level is detected.
2. Question: Can it be connected to the MCU IO port?
Answer: It can be directly connected to the IO port of the microcontroller.
3. Question: What is the resistance value if a pull-up resistor is added?
Answer: The resistance value of the pull-up resistor is generally about 10K,
4. Q: Why does the indicator light keep on after connecting the power?
Answer: First of all, ensure that the power supply is stable 5V±2%, and secondly, the probe output end cannot be connected to the output port of the single-chip microcomputer,
5. Q: Why does the indicator light keep on after connecting the infrared switch power supply?
Answer: 1. Please check whether the power supply is reversed, that is, the infrared output is connected to the power supply, 2. Please check whether there are obstacles in the detection range of the direction of the probe, so as to face the open direction.
6. Q: Is the instruction manual too simple?
Answer: This is a photoelectric switch with only three wires, power supply, ground, and output. It doesn't need to be too complicated.
7, Question: Is the infrared obstacle avoidance sensor NPN?
Answer: yes
