Product introduction

1. The object output 0 is sensed, while the output 1 is not sensed, it can be directly connected to the IO port of the 3V and 5V MCU.

2. The sensing distance is 2 to 40 cm, which is far away and has good anti-interference ability. (Note: The infrared sensor can not detect all objects at the same distance. Objects of different colors have different reflectivity to light. The darker the color of the object, the closer it is to black, and the shorter the detection distance. The sensor measures 2 to 40 cm against the white wall.)

3. Fast speed, suitable for intelligent car obstacle avoidance, black and white line tracking, fall prevention, product counter, assembly line cutting, liquid level detection, etc.

4. The black and white line tracing car made with this sensor does not need to run on the white paper and black lines, but can patrol the black lines in complex environments such as cement ground and yellow mud ground. As long as the color around the black line is slightly lighter than the black line, the traditional walking method is eliminated and the environmental layout is simpler.

5. The sensor is powered by 3 to 6V, with an ultra wide range, and is suitable for 3V and 5V single-chip systems.

6. With enable terminal, the sensor will not work when the EN terminal is equal to "1", and will work when the EN terminal is equal to "0". After the jumper cap on the sensor is plugged in, the EN terminal is grounded for a long time (the EN terminal is "0" for a long time). Please remove the jump cap when using the EN terminal.

7. The frequency adjustment potentiometer is used to adjust the carrier frequency of the infrared transmitting tube, because the integrated receiver is most sensitive at a specific carrier frequency of 38KHZ. Turn the 502 resistor clockwise to the end (that is, turn the brightness of the emitter tube to the maximum), and then adjust the 103 resistor to the white wall until the sensing distance is the farthest, so that the sensor works in the best state.
