Lonely Binary E18-D80NK Infrared Proximity Distance Sensor
Product Information
Specifications
- Adjustable distance detection range: 6 cm – 80 cm
- Output: Logic TTL; 0 (GND) and 1 (5V)
- Output type: Open Collector
- Signal Output: Digital TTL; 0 = GND, 1 = 5V
- Power Supply: DC 5V, Current 100mA
Product Usage Instructions
Setup Distance Detection
- Provide 5V Power Supply (brown cable) and GND (blue cable) to the Sensor.
- Position the Sensor upright towards the ground or wall (preferably black).
- Measure the preferred distance detection from the ground or wall to the head of the Sensor using a ruler.
- Adjust the VR at the end of the Sensor while observing the LED status at the end of the Sensor.
- Test the operation of the Sensor by moving it. The LED will light up if the detected distance is within the specified range.
Using Sensor After Setup
Connect the Sensor with connectors according to the specified colors: Brown cable (5VDC), Blue cable (GND), Black cable (OUTPUT/TTL).
IR – Sensor Switch E18
This is Sensor Infrared device for distance detection that can be adjusted in the range of 6 cm.-80 cm.; and
Output is Logic TTL; 0 (GND) and 1 (5V).
Specifications
- Adjust distance detection in the range of 6 cm.-80 cm. by Adjustable VR and display the status by LED
- Sensing device should be opaque material or any material that allows less light to pass through; black color is the best because Sensor device works well by using reflection of Infrared
- OUTPUT is Open Collector; it has to connect R 10 K Pull Up at Out Putt
- Signal Output is Digital TTL; 0 = GND and 1 = 5V
- Use Power Supply DC 5V Current 100mA
How to setup distance detection
Before using, it has to setup preferable distance detection for using with Sensor as follows;
- Provide 5V Power Supply (brown cable) and GND (blue cable) to Sensor
- Turn the head of Sensor upright to the ground or wall (it is the best if ground or wall is black color)
- Measure the preferable distance detection from ground or wall to the head of Sensor by ruler; and hold Sensor at the preferable position to detect for a while
- Adjust V R at the end of Sensor. Look at the change of LED at the end of Sensor as described below;
- If LED is OFF (OUTPUT = 1), please adjust VR in a clockwise direction until LED becomes ON (OUTPUT = 0) and then stop adjusting VR. The position that LED changes the state is the specified distance detection. This is conditional operation; if the distance of Sensor is less than or equal to the distance detection, LED Status is ON and OUTPUT becomes Logic 0; but if the distance of Sensor is greater than the distance detection, LED Status is OFF and OUTPUT becomes Logic 1 instead.
- If LED is ON (OUTPUT = 0), please adjust VR in an anticlockwise direction until LED becomes OFF (OUTPUT = 1) and then stop adjusting VR. The position that LED changes the state is the specified distance detection. This is conditional operation; if the distance of Sensor is greater than or equal to the distance detection, LED Status is OFF and OUTPUT becomes Logic 1; but if the distance of Sensor is less than the distance detection, LED Status is ON and OUTPUT becomes Logic 0 instead.
- Test the operation of Sensor by moving Sensor. When the head of Sensor moves and passes the specified distance detection, LED of Sensor is lit up if the distance of Sensor is less or equal to the specified distance detection; but LED is OFF if the distance of Sensor is greater than or equal to the specified distance detection. If it does not accord with any conditional operation described above, it means that it fails to setup any distance detection for Sensor.
Referred to experiment in use, it found that color of ground or wall or any material that is used to reflect to Sensor is not enough dark. If the wall that is used to reflect is light color, the least distance detection of Sensor is also higher; so, the specified distance detection of user is lower than the least distance detection of Sensor. In this case, it should use wall with the dark color or it may set the distance detection higher, depend on material of user. User has to test and setup distance detection by self because each color of wall that reflects to Sensor is different; and finally, user needs to return to step 1-5. Referred to the experiment, the least distance detection of the black wall that can reflect to Sensor is 6 cm; the operating result accords with step 5, it means that it succeeds and Sensor is ready to use and connect.
How to use Sensor after setup distance detection
Please look at the circuit below and connect Sensor with Connectors according
to the specified color; Brown Cable is 5VDC Power Supply, Blue Cable is GND,
and Black Cable is OUTPUT(TTL). Next, please look at the conditional operation
of Sensor to write program correctly.
FAQ
Q: What should I do if the Sensor fails to detect distances accurately?
A: If the Sensor is not detecting distances accurately, consider adjusting the VR to fine-tune the detection range. Also, ensure that the material used for reflection is opaque and preferably dark in color for better performance.
Q: How do I troubleshoot if the LED does not light up during testing?
A: If the LED does not light up during testing, check the power supply connections and ensure they are providing the correct voltage. Additionally, verify that the Sensor is positioned correctly and that there are no obstructions affecting its detection capabilities.
