Custom Smart Car Robot E18-D80NK Infrared Obstacle Avoidance Photoelectric Sensor Proximity Switch 3-80cm Detection Range Adjustable

This is a photoelectric sensor that integrates transmission and reception. The detection distance can be adjusted according to the requirements. The sensor has detection

Long distance, small interference by visible light, cheap, easy to assemble, easy to use, etc., can be widely used in robot obstacle avoidance, (but this infrared sensor is not suitable for use in natural light lighting environment, because natural light contains infrared, need to use infrared probe friends please pay attention to this problem, used in non-infrared environment is still OK)

Many automation products such as assembly line piecework.

Answers to frequently asked Questions about Sensors:

1. Q: Is this a digital sensor or an analog sensor?
A: 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 the high level, and the target output low level is detected.
2, Q: Can be connected to the MCU IO port?
A: Can be directly connected to the MCU IO port to use.
3. Q: What is the resistance value if the pull resistance is added?
A: The resistance value with the pull resistance is generally about 10K;
4, Q: Why is the indicator light always on after connecting the power supply?
A: First of all, ensure that the power supply is stable 5V±2%, followed by the probe output can not be connected to the MCU output;
5, Q: Why is the indicator light always on after connecting the infrared switching power supply?
A: 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 any obstacles in the detection range of the direction of the probe, and it is better to face the direction of the open.
6. Q: Is the instruction manual too simple?
A: This is a photoelectric switch, only three lines, power, ground, output, do not need to be too complicated introduction.

7, Ask: infrared obstacle avoidance sensor is not NPN

A: Yes
