4-way infrared tracking; tracking module; patrol line module; obstacle avoidance car; robot; sensor

1. Operating Voltage: DC 3.3V-5V 2. Operating Current: try to choose more than 1A power supply 3. Working temperature: -10 ℃ - +50 ℃ 4. Install Aperture: M3 screws 5. Detection range: 1mm to 60 CM adjustable, the closer the more stable performance , white reflective distances. 6. Size: the control panel 42mm x 38mm x 12mm ，Small plates forward 25mm x 12mm x 12mm 7. Output Interface : 6 -wire interface (1234 4 -way signal output, + positive power - power that is negative ground) 8. Output signal: TTL level (can be directly connected microcontroller I/#0, is reflected back to the sensor sensing infrared light, the red light is on, the output low; when no infrared light, the light is not bright, high power output level.)
