Description
1、Product overview:
DJLK-001-V2 ultrasonic ranging small angle housing waterproof module is designed by using non-contact ultrasonic detection technology. In the range of 1cm to 600cm, the product can accurately detect the distance from plane objects, and in the range of 1cm to 230cm, it can accurately measure people.
Basic working principle: This ultrasonic ranging control module has a power supply of 10-30V and senses the output of object relay within the sensing range.
2、product application
1. Horizontal ranging;
2. Avoidance and automatic control;
3. Objects approaching and being perceived
4. Traffic control;
5. Security and industrial control;
6. Artificial intelligence, teaching and research
3、Product introduction
This product DJLK-CB-001-V2 can be matched with a variety of ultrasonic ranging modules with serial port output, and can customize the practical measuring range with digital tube display and realize double outputs of relay normally open and normally closed.

The adjustable range is 22cm-600cm 2 The farther the measurement distance, the greater the error, which basically accords with the linear proportional relationship.
instructions
This product can customize the trigger range of the relay, for example, the detection range of the ultrasonic module is 0- 600cm, the actual application scene needs 0 -200cm to trigger the relay output, and other measured values are not triggered, which can be freely set through the button of this product.
The operation is as follows
instructions
This product can customize the trigger range of the relay, for example, the detection range of the ultrasonic module is 0- 600cm, the actual application scene needs 0 -200cm to trigger the relay output, and other measured values are not triggered, which can be freely set through the button of this product.
The operation is as follows
Step 1, press the set key for a long time until the digital tube flashes, and enter the upper limit setting mode. The value displayed by the test digital tube is the upper limit of relay triggering.
In the second step, modify the setting value by +and -keys. Press short to increase/decrease by 1cm by default, and press long to continuously increase or decrease.
Note that the set upper limit value needs to be greater than the blind area value of the matching module and less than the maximum range of the ranging module.
