Product description
6-way patrol module
Reminder: Module shipments are only guaranteed to have a light off response, indicating that the module is functioning properly. If you need to adjust the resistance value for high or low, please adjust it yourself, it is not within the scope of after-sales service.
Product Introduction
The infrared emitter tube of each sensor continuously emits infrared radiation. When the emitted infrared radiation is not reflected back or is reflected back but the intensity is not strong enough, the infrared receiver tube remains in the off state. At this time, the TTL output terminal of the module is at a high level, and the corresponding indicator diode remains in the off state; When the detected object appears within the detection range, the infrared rays are reflected back and the intensity is strong enough. The infrared receiver tube conducts, and the TTL output terminal of the module is at a low level, indicating that the diode is lit up.
Testing:
After powering on, use your fingers to cover each infrared sensor contact and check if the indicator light on the line inspection module changes on or off. If the on-off transition can occur normally, it means that the module can be used normally.
Adjustment:
When the sensor receives the reflected infrared light, the corresponding indicator light will light up, and this distance is the critical distance. The potentiometer corresponding to the infrared sensor can be rotated (adjusted) to adjust the size of this critical distance.
Application field
Suitable for various smart cars
Installation Diagram
Scope of application
1. Intelligent cars or robots patrol lines (including black and white lines), following the black line path, also known as patrol.
2. Intelligent car avoids cliffs and prevents falls.
3. Intelligent car obstacle avoidance
4. Can be applied to other automated optoelectronic reflection applications.
Precautions
1. When using this module, avoid direct sunlight on the probe. Light has an interference effect on modules.
2. Sensitivity adjustment should not be too high, as excessive sensitivity may cause false triggering.
3. At the critical value, there will be a slight brightness of the LED, which is an unactivated state. At this time, the output is at a high level.

Technical Support
The design accuracy of most of our products is based on teaching demonstration standards. If you wish to use our products in other application fields (such as industrial, consumer, etc.), please evaluate your secondary development capabilities and accuracy conditions on your own. Our store only ensures that the product can be installed and run after it reaches the user's hands, while maintaining the original factory software and hardware system.
In addition, we do not provide any after-sales technical support for operations that are inconsistent with the original factory state, such as verifying functions through command line, modifying code by oneself, secondary development, replacing software and hardware environments, and vehicle structure. If you encounter problems in this regard, you can combine our information and restore the system firmware to the factory state to investigate the cause.
