เซ็นเซอร์ตรวจจับสิ่งกีดขวาง IR Infrared Obstacle Avoidance Sensors Module For UNO Smart Car Robot Detection

product description :

1. Sensor output 0, not sensed when the output 1, can be directly connected with the 3V and 5V MCU IO port.

2. Sensing distance of 2 to 40 cm, distance, anti-interference ability. (Note: the infrared sensor is not detected all objects can get the same distance, different colors of objects on the light reflectivity is different, the deeper the color of the object closer to the black detection distance is shorter, the sensor 2 to 40%

Meter is measured against the white wall out)

3. Speed, suitable for intelligent car to avoid obstacles, black and white line tracking, anti-drop, product counters, pipeline cutting, liquid level detection.8

4.With this sensor to produce black and white line tracing car without running on the black line in white, in the cement, yellow mud and other complex environment of black lines. As long as the black line around the color slightly darker than the black can be, eliminating the traditional method of walking, so that the environment layout more simple.

5. The sensor 3 to 6V power supply, wide range, suitable for 3V and 5V single-chip system.

6. With the enable side, the EN terminal is equal to "1" when the sensor does not work, equal to "0" when the work. The sensor is permanently connected to the EN terminal after the hood is plugged in (EN long "0"). To use the EN terminal, please remove the jump cap.

7. Frequency adjustment potentiometer is used to adjust the infrared emission tube carrier frequency, because the integration of the first receiver in a specific 38KHZ carrier frequency is the most sensitive. Will 202 resistance clockwise transferred to the best (that is, the maximum brightness of the launch tube), and then align the white wall of the resistance of 103, has been transferred to the sensor distance is farthest, so the sensor to work in the best condition
