Description:
- sensed object output 0, output 1 is not sensed, it can be directly connected with 3V and 5V MCU IO port.
- The sensing distance 2-40 cm, long distance, anti-jamming capability. (Note: The infrared sensor can not detect all objects get the same distance, objects of different colors for different light reflectivity, the deeper the color of the object, the shorter the distance closer to the black testing, the sensor 2-40 cm
- M is measured against a white wall)
- speed, suitable for intelligent car obstacle avoidance, black and white line tracking, anti-drop, product counter, line cutting, level detection.
- This sensor is made of black and white line tracing the car without the black line running in white, can patrol track in concrete, Wong and other complex environments to black. As long as black lines surrounding colors than black can be a little light, eliminating the traditional moves, make the environment more simple arrangement.
- The sensor 3 to 6V supply range wide, suitable for 3V and 5V microcontroller system.
- With enabled client, EN terminal is equal to “1” when the sensor does not work, equal to “0” at work. EN end of the long jump after grounding plug cap on sensor (EN long as “0”). Please remove the jumper cap to be used when EN end.
- A frequency adjust potentiometer is used to adjust the carrier frequency infrared emission tube, because integration in time to receive the first specific 38KHZ carrier frequency is the most sensitive. The 202 resistor clockwise transferred to do (that is, the brightness of the launch tube to maximum), and then at a white wall tone 103 resistance, has been transferred to the sensing distance is the farthest so far, so that the sensor will work in the best state.
