4 road Infrared Tracing Module / Patrol Modules / Obstacle Avoidance for diy robot car

Specification:

1.Working voltage:DC 3.3 V to 5 V

2.Working current: try to choose more than 1 a power supply

3.Working temperature: -10°-+50°

4.Install the aperture:The M3screw

5.Detection distance:1 mmAdjustable to 60 , the closer distance performance is more stable, white reflection point farthest.

6.Size: the control board42 mmx38 mmX 12Mm (longX widthxhigh)

Small plate forward 25mmx12 mmX 12Mm (longX widthxhigh)

7.Output interface:6Wire interface(1234For 4 road signal output terminal, +Positive power supply, -Negative power supply is the earth wire)

8.The output signal:TTLLevel (can be directly connected microcontrollerI / 0Number, induction to the reflected infrared sensor,The red light is lit, the output low level;There is no infrared light,Light is not , high output level.)
