E18-D80NK, infrared obstacle avoidance sensor, 3-80cm adjustable, proximity switch, smart car

The sensor consists of a transmitter and an infrared receiver.
The component works like a radar, ie it emits a signal and expects its echo if there is an obstacle in operation.
Measuring the time that passes from transmission to reception and knowing that light propagates at a speed of 6.6ns / m (round trip) you can derive the obstacle distance.
Supply voltage 5V.



Photoelectric switch E18 technical parameters:
1, the output current DC / SCR / Relay Control output: 100mA/5V powered
2, the DC current consumption <25mA
3, response time <2ms
4, point angle: ? 15 °, effective distance 3-50CM adjustable
5, detection of objects: transparent or opaque body
6, the working environment temperature: -25 °C ~ 55 °C
7, the standard sensing object: sunlight 10000LX The following incandescent 3000LX
8, Case Material: Plastic

 

Electrical characteristics:
     
U: 5VDC
     
I: 100mA
     
Sn :3-50CM

2, multi-function reminder
     
3, Maze Robot

[Note] for reliable and long life protection action, under the conditions of the relevant provisions of the outside temperature outside (outdoor) Avoid proximity sensor water structure, mounted on the hood, not allow water and water capacitive cutting oilleaching to be better to improve the reliability and lifetime. Please also avoid the chemicals used, especially in alkali, acid, nitric acid, Ming acid, hot concentrated sulfuric acid, etc. climate.


Red: then 4.5-5V supply high level

Yellow: connected microcontroller output TTL level to the microcontroller

Green: GND 0V to power low level

Front Accessible output high, there is an obstacle to the output port (yellow) level from high into low, a rear view of a potential obstacle detection distance can be adjusted, once adjusted potentiometer (such as the regulation of maximum distance of 50cm) in the effective distance (such as 40cm at obstructions, 10cm at obstacles) output low, low just to the microcontroller to identify.

Pull-up resistor 10K to 5V output of the yellow line circuit design can then access the microcontroller detection would be more stable, the microcontroller can be detected by external hardware interrupt INT0 INT1 to
