Features: Brand new and high quality Object is sense output 0, output 1 is not sensitive to-time, directly with 3V and 5V microcontroller port connect Sensing distance 2-40cm, distance, good anti-jamming capability. Suitable for car obstacle avoidance, black and white line track, anti-drop, product counters, cutting lines, liquid level detection. This sensor is made with black and white lines tracing the car run without black lines on white paper, available in concrete The yellow complex environment such as the black lines patrol track. As long as the black lines around the slightly lighter color than black can, eliminating the traditional moves, so that environmental layout easier. The sensor 3 to 6V supply, wide-range, suitable for 3V and 5V MCU system. Specifications: Material:PCB Working voltage: 3.3V-5V Working current: 20mA Working temperature: -10degree+50degree Detection distance : 2-40cm Effective angle: 35° Size: Approx.4.4x1.7cm/1.73x0.67inches Package Includes: 1x Avoidance Sensor note: 1.Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order. 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item.
