Related sensor Frequently Asked Questions answered:
1) Q: This is a digital sensor or analog sensors?
A: This is a digital sensor, NPN normally open type photoelectric switch; output state is 0, 1, in digital circuits, low and high, the output of the normal state of high to detect the target output low.
2) Q: Can connected to the microcontroller IO port?
A: can be directly connected to the microcontroller IO port.
3) Q: How much to pull the resistance?
A: The pull-up resistor is generally about 10K;
4) Q: Why is connected to the power indicator is always on?
A: Firstly, to ensure that power is stable 5V ± 2%, followed by the probe output can not be connected to the microcontroller output port;
5) Q: Why is connected to the infrared switching power supply, the indicator is always on?
A: 1, check the power reversed, that is, the infrared output to the power is;, check the probe to the detection range, there are no obstructions in the right direction, preferably in front of the open direction.
6) Q: manual description is too simple?
A: This is a photoelectric switch, only three lines, power supply, the output does not require too complex to introduce.
7) Q: I want to know the original and the internal circuit diagram of the sensor internal work.
A: I want to, but the factory does not give.
