4-way Infrared Line Tracking Module (โมดูลตรวจจับเส้นสำหรับ Smart Car)

4 way Infrared Line Tracking Module (โมดูลตรวจจับเส้นสำหรับ Smart Car)

ใช้สำหรับการตรวจจับเส้นสีขาวและดำของ Smart Car เพื่อหลบหลีกหรือเดินตามเส้น  ใช้หลักการของการตรวจจับ Infrared ที่สะท้อนมาจากเส้น  แต่ละชุดมี 4 ตัวรับค่า  

Application:

1. Smart car or robot hunt (black and white lines), tracing module.

2. Smart car for obstacle avoidance

3. Can be applied to other automation photoelectric reflective applications.

Specifications:

1. Operating voltage: DC 3.3V-5V

2. Operating Current: Choose more than 1A power supply

3. Operating Temperature: -10 ° C - +50 ° C

4. Mounting aperture: M3 screw

5. Detection distance: 1mm to 60cm adjustable, Distance closer the performance is more stable, the white reflection farthest.

Module features:

Per 1 channel sensor continuously emits an infrared infrared emission tube, but the strength is not large enough, the infrared receiving tube has been in a shutdown state, the module TTL output is high when the infrared rays emitted without being reflected back or reflected back levels corresponding directions diode has been in the OFF state; when the object to be detected in the detection range, the infrared ray is reflected back and the strength is large enough, the infrared receiving tube conduction module TTL output is low, indicating The diode is lit.

Wiring instructions:

1. DO1 - Road TTL-level output

2. DO2 - 2-way TTL-level output

3. DO3 - 3-way TTL-level output

4. DO4 - 4-channel TTL level output

5. GND - negative.

6. VCC - positive power supply
