Milesight EM310-UDL LoRaWAN Ultrasonic Sensor User Manual

1. Giới thiệu

The Milesight EM310-UDL is a state-of-the-art LoRaWAN ultrasonic distance sensor designed primarily for monitoring fill levels in waste bins and other containers. Its compact design and wide measurement range make it suitable for various applications, including solid or liquid level detection. Additionally, the EM310-UDL integrates a 3-axis accelerometer to detect the status of the container cover, providing comprehensive monitoring capabilities.

This sensor is fully compliant with Milesight LoRaWAN® gateways and the Milesight IoT Cloud solution, enabling real-time remote monitoring of container status and fill levels via web browsers or mobile applications. The EM310-UDL is widely applicable in waste management, water tank monitoring, and manhole cover monitoring.

Sensor data can be transmitted efficiently using LoRaWAN technology, ensuring low power consumption and an extended battery life of over 3 years with two replaceable batteries. When combined with Milesight LoRaWAN gateways and the Milesight IoT Cloud solution, users can manage all sensor data remotely and visually.

4. Thiết lập và Cài đặt

Before installing your EM310-UDL sensor, ensure you have access to a compatible LoRaWAN® gateway and a Milesight IoT Cloud account or another suitable cloud platform for data management.

4.1 Mở hộp và kiểm tra ban đầu

Carefully remove the sensor from its packaging. Inspect the device for any visible damage. The package should contain the EM310-UDL sensor unit.

4.2 Kích hoạt thiết bị

1. Bật nguồn: The EM310-UDL typically comes with pre-installed batteries. Refer to the specific product documentation for initial power-on procedures, which may involve removing a battery insulation tab or pressing a button.
2. LoRaWAN® Configuration: Configure the sensor with your LoRaWAN® network server. This usually involves entering the device's DevEUI, AppEUI (or JoinEUI), and AppKey into your network server's interface. These credentials are typically found on a label on the device or in its packaging.
3. Kết nối mạng: Once configured, the sensor will attempt to join the LoRaWAN® network. Ensure your gateway is within range and properly configured.

4.3 Gắn cảm biến

The EM310-UDL is designed for easy installation. Consider the following when mounting:

• Vị trí: Mount the sensor vertically above the area where the fill level needs to be measured (e.g., inside a waste bin, above a water tank). Ensure the ultrasonic beams have a clear path to the surface of the material being measured, free from obstructions.
• Sự ổn định: Securely fasten the sensor using appropriate screws or mounting hardware through the designated mounting tabs.
• Những cân nhắc về môi trường: While robust, avoid direct exposure to extreme weather conditions or environments that exceed its operating temperature and humidity specifications.

5. Operating the EM310-UDL

Truyền dữ liệu 5.1

Once connected to the LoRaWAN® network, the EM310-UDL will periodically transmit data packets containing ultrasonic distance measurements and accelerometer status (for cover detection). The frequency of these transmissions can often be configured via downlink commands from your LoRaWAN® network server or Milesight IoT Cloud.

5.2 Interpreting Data

• Khoảng cách siêu âm: This value represents the distance from the sensor to the surface of the material being measured. A decreasing distance indicates an increasing fill level.
• Accelerometer Data: The 3-axis accelerometer provides information about the sensor's orientation and movement. This is primarily used to detect if a container lid is open or closed, or if the container itself has been moved or tampđược gắn với.

5.3 Using Milesight IoT Cloud

For optimal data visualization and management, integrate your EM310-UDL with the Milesight IoT Cloud platform. This platform allows you to:

• View real-time and historical fill level data.
• Set up alerts and notifications for specific fill levels or cover status changes.
• Manage multiple sensors and gateways from a single dashboard.
• Configure sensor parameters remotely.

6. Bảo trì

6.1 Vệ sinh

Periodically inspect the ultrasonic transducers for any dirt, dust, or debris that might obstruct the signal. Gently clean the surface with a soft, dry cloth. Do not use abrasive cleaners or solvents.

6.2 Thay thế pin

The EM310-UDL is designed for long battery life. When the battery level is low (indicated by your monitoring platform), replace the two internal batteries. Refer to the specific product guide for instructions on safely opening the casing and replacing the batteries to maintain the device's IP rating.

6.3 cập nhật chương trình cơ sở

Milesight may release firmware updates to improve performance or add new features. Check the official Milesight website for the latest firmware and instructions on how to perform updates, typically via LoRaWAN® downlink or a dedicated tool.
