4 Channel Infrared Tracking Line Sensor Module Transmission Obstacle Avoidance for Arduino DIY Smart Car Robot

Specification:
1.Operating voltage: DC 3.3V-5V
2.Operating Current: try to choose more than 1A power supply
3.Operating Temperature: -10 -50°C
4.mounting aperture: M3 screw
5.detection distance: 1mm to 60 cm adjustable closer the performance is more stable, the white reflection farthest.
6.Size: the control board 4.4mm × 4.0mm × 12mm (L × W × H)
Small plate forward 25mm x 12mm x 12mm (L × W × H)
The output interface: 6-wire interface (1234 for the 4-way signal output terminal, + positive power, - the negative power supply is ground)
Output signal: TTL level (directly connected microcontroller I / 0, sensitive to infrared light reflected back by the sensor, the red light is on, the output low; absence of infrared light, the light does not shine, the output high level.)
Application:
A smart car or robot hunt (including black and white lines), walking along the path of the black line, also known as tracing.
Smart car to avoid the cliff, anti-drop.
Smart car for obstacle avoidance
Package Included:
1 x tracking module sets (hollow board + board forward four)
1 x ?20cm DuPont line 18 for easy wiring
