Sensors answer frequently asked questions about :
1 , Q: This is a digital sensor or analog sensors
A: This NPN type photoelectric switch. Output Group Aung station is 0,1 , namely a digital circuit high and low
2, Q: What is the level of output is detected the target object ?
A: The goal is to detect low-level output , the normal state is high output
3 , Q: Can the microcontroller IO port received ?
A: The output of an external pull-up resistor can be connected to the IO port
4 , Q: How much pull-up resistor ?
A: pull-up resistor is generally about 1K
5, Q : Where can I download the manual ? Or manual too simple
A: This is a photoelectric switch, three lines , power, ground and output , not too complicated introduce digital output , does not require AD conversion can be directly connected to the microcontroller IO port on the rear of the adjustable potentiometer to adjust the distance ( 3 -80CM valid )
