Gravity: Digital Adjustable Infrared Proximity Sensor

SKU: SEN0019

The DFRobot Digital Adjustable Infrared Proximity Sensor integrates a transmitter and receiver into one photoelectric switch. Its detection distance is user-adjustable. Small, easy to use, inexpensive and easy to assemble, it’s widely used in robot obstacle avoidance, interactive media, industrial assembly lines, etc. The output is high without obstacles and low with them. A red LED on its back indicates status.

    FAQ

    • Hi, can the analog Infra red sensor work through the digital 5A relay to control a Solenoid valve?

      It should work, it's just a digital sensor that give high or low level signal.

    • If I need a pull-up resistor, how much resistance should it have?
      About 10K.
    • Why does the light turns on when I connect the infrared switch power?
      Please first check the power supply, make sure the lines are not reversed, in a word, the infrared output to supply should be positive; Second, check the probe, make sure it pointed in the correct deriction with no obstacle in its path.
    • Why does the light not turn on when I connect the power?
      Ensure stable a power supply of 5V ± 2%, followed by the output of the probe is not connected to the microcontroller output port.
    • We have to use the manual because the description is too simple?
      This is a photoelectric switch and only have three lines which are : power, ground and output, Therefore its presentation is not too complicated.
