SPECIFICATIONS

Features:

1. Accurate ranging: Ultrasonic ranging sensors can effectively achieve accurate distance measurement, provide accurate and reliable data, and reduce the risk of parking or reversing.

2. Automatic alarm: Built-In buzzer, when the distance between the vehicle and the obstacle is too close, the system will automatically alarm to remind the driver to pay attention, which greatly improves the safety of driving.

3. Reversing radar sensing: The radar sensing module can feed back the situation behind the vehicle in time, and can effectively perceive the surrounding environment even when the line of sight is not good, making reversing more convenient and safer.

4. Distance can be set: users can set the early warning distance according to their own needs, making the ranging system more personalized and practical.

5. Easy to install and use: The module is exquisite in design, convenient to install, and does not require complicated operations. Users can easily complete the installation and setting according to the instructions, providing drivers with a convenient experience.

Product introduction:

This product (DJLK-003A) ultrasonic distance measuring module with relay output can set the detection distance by itself, and the relay output can be controlled within the set distance

product applications:

1. Horizontal ranging;

2. Obstacle avoidance and automatic control;

3. Objects approaching and being aware

4. Traffic control;

5, security, industrial control;

6.Artificial intelligence, teaching and research

Setting instructions:

This product can customize the trigger range of the relay, such as the ultrasonic module detection range of 5cm-500cm, the actual application scenario requires 100cm trigger relay output, which can be freely set by the button of this product

The specific operation is as follows

The first step is to place the probe against a plane (such as a wall) to 100cm

The second step, long press the "distance setting key" for more than 2S, the green indicator light will flash once and the setting is completed. When it is less than 100cm, the work indicator light is always on and the relay is closed.
