Midzooparts Ultrasonic Reversing Radar Sensor Module (Model DJL-CB-001-V1) Instruction Manual

1. Introduction

This manual provides detailed instructions for the Midzooparts Ultrasonic Reversing Radar Sensor Module, Model DJL-CB-001-V1. This module utilizes non-contact ultrasonic detection technology to accurately measure distances to objects. It is designed for various applications requiring precise distance sensing and relay output control.

2. Product Overview and Features

The DJL-CB-001-V1 is an ultrasonic ranging module featuring a digital display and relay output. It can detect distances from 1cm to 400cm for planar objects and 1cm to 150cm for human detection. The module integrates a serial port output for customizable measurement ranges and offers both normally open and normally closed dual relay outputs.

Key Features:

• Non-contact ultrasonic detection for accurate distance measurement.
• Integrated digital tube display for real-time distance readings.
• Configurable measurement range (28cm to 400cm).
• Relay output with normally open (NO) and normally closed (NC) contacts.
• Wide input voltage range: 10V to 30V.
• Waterproof probe for diverse environmental conditions.

3. Specifications

Note: The adjustable range is 28cm-400cm. Measurement accuracy may decrease with increased distance, generally following a linear proportional relationship. The measuring angle characteristics are influenced by the object's surface and orientation.

4. Setup and Installation

Proper installation is crucial for the optimal performance of the ultrasonic sensor module. Ensure all connections are secure before applying power.

4.1 Component Identification:

Figure 1: Midzooparts Ultrasonic Sensor Module with its components. This image shows the main circuit board, the red digital tube display, the ultrasonic probe connected via a cable, and various terminals for power and relay output. The display currently shows '2.8.8', likely a test or default value.

Figure 2: Midzooparts Ultrasonic Sensor Module in operation. This image is similar to Figure 1 but shows the digital display indicating '2.6', suggesting a distance reading. A green LED indicator is also visible, likely indicating power or active sensing.

4.2 Wiring Instructions:

1. Power Connection: Connect the power supply (10V-30V DC) to the designated input terminals on the module. Observe correct polarity.
2. Ultrasonic Probe: Ensure the waterproof ultrasonic probe is securely connected to its port on the module.
3. Relay Output: Connect your external device or circuit to the relay output terminals (normally open/normally closed) as required by your application.
4. Data Port (Optional): If serial communication is required for advanced configuration or data logging, connect to the 5V TTL data port.

Mount the ultrasonic probe in a location where it has a clear line of sight to the target object, free from obstructions that could interfere with the ultrasonic waves.

5. Operating Instructions

Once the module is correctly wired and powered on, it will begin to operate automatically.

1. Power On: Apply power within the specified 10V-30V DC range. The digital display should illuminate.
2. Distance Measurement: The module continuously emits ultrasonic waves and measures the time it takes for the echo to return. The calculated distance to the nearest object within the detection range will be displayed on the digital tube.
3. Relay Activation: When an object is detected within the pre-set sensing range, the integrated relay will activate. This can be used to trigger external devices, alarms, or control systems. The relay provides both normally open (NO) and normally closed (NC) contacts for flexibility.
4. Adjusting Sensing Range: The module allows for customization of the actual practical measurement range. Refer to the product's detailed technical documentation or serial port communication protocol for specific instructions on adjusting this parameter.

The module is designed for continuous operation within its specified parameters.

6. Applications

The Midzooparts Ultrasonic Reversing Radar Sensor Module is suitable for a wide range of applications, including:

• Horizontal ranging and distance monitoring.
• Barrier prevention and automatic control systems.
• Object proximity detection and awareness systems.
• Traffic control and vehicle detection.
• Security and industrial automation control.
• Educational and research projects in artificial intelligence and robotics.

7. Troubleshooting

If you encounter issues with your ultrasonic sensor module, consider the following common troubleshooting steps:

• No Display/No Power:
  • Verify that the input voltage is within the 10V-30V range.
  • Check power supply connections for correct polarity and secure contact.
  • Ensure the power source is functional.
• Inaccurate Readings:
  • Ensure the ultrasonic probe has a clear path to the target object, free from obstructions.
  • Check for environmental factors such as strong air currents, extreme temperatures, or acoustic noise that might interfere with ultrasonic waves.
  • Verify the target object's surface is suitable for reflection (e.g., not highly absorbent or irregularly shaped).
  • Note that accuracy decreases with greater distances.
• Relay Not Activating:
  • Confirm that an object is within the configured sensing range.
  • Check the relay connections to your external device.
  • Ensure the relay is receiving power and is functional.
• Intermittent Operation:
  • Inspect all wiring for loose connections.
  • Check for electromagnetic interference from nearby equipment.

If problems persist, consult the manufacturer's technical support or detailed product documentation.

8. Maintenance

The Midzooparts Ultrasonic Sensor Module is designed for low maintenance. Follow these guidelines to ensure longevity:

• Cleaning: Keep the ultrasonic probe clean and free from dust, dirt, or debris that could obstruct the sensor. Use a soft, dry cloth for cleaning.
• Environmental Conditions: Operate the module within its specified temperature and humidity ranges. While the probe is waterproof, the main module should be protected from excessive moisture unless otherwise specified.
• Connections: Periodically check all electrical connections to ensure they remain secure.
