Sensitive to objects output 0, not sensitive to output 1 can be directly connected to the 3V and 5V MCU IO port.

Sensing distance 2-30 cm distance, anti-interference ability. (Note: the infrared sensor does not detect all of the objects can be obtained to the same distance, the reflectance of the different color of the object on the light, the deeper the color of the object the closer of black detection shorter the distance, the sensor 2-30 cm It is measured against the white wall)

speed, for smart car obstacle avoidance, and black-and-white line tracking, anti-drop counter, pipeline cutting, liquid level detection.

Production of black-and-white line with this sensor tracing the car without in White black line running, complex environment in the concrete floor, The yellow black line patrol track. The black line around the slightly lighter in color than black and can eliminate the traditional moves, the layout of the environment is more simple.

3 to 6V supply sensor , ultra-wide range, suitable for 3V and 5V MCU system.

with the enable terminal EN terminal is equal to "1" when the sensor does not work, is equal to "0" when the work. Jump on the sensor cap plug EN end of the long-term ground (EN long "0"). Please remove the jumper cap is to use the EN terminal.

Frequency adjusting potentiometer is used to adjust the infrared transmitter carrier frequency of the tube, because the integrated receiving head when specific 38KHZ carrier frequency is the most sensitive. Transferred to the 502 resistance clockwise best (that is, the brightness of the launch tube to maximum), and then aligned white wall tone 103 resistance, has been transferred to the sensing distance is the farthest date, so that the sensor is in the best condition.
