1. Product Introduction

1.1 Overview

EM310-UDL is a LoRaWAN® ultrasonic distance/level sensor mainly used for detection of waste bin and other container's level. With a compact size and wide measure range, EM310-UDL can be installed to any types of waste bins or containers to monitor solid or liquid level. Besides, EM310-UDL equips with 3-axis accelerometer to detect the status of container cover. It is equipped with NFC (Near Field Communication) and can easily be configured by a smartphone.

Sensor data are transmitted in real-time using standard LoRaWAN® protocol. LoRaWAN® enables encrypted radio transmissions over long distance while consuming very little power. The user can obtain sensor data and view the trend of data change through Milesight IoT Cloud or through the user's own Network Server.

1.2 Features

• 3 to 450 cm wide measuring range with short bind zone
• Support temperature compensation for high accuracy
• Up to 15 km communication range
• Easy configuration via NFC
• Standard LoRaWAN® support
• Milesight IoT Cloud compliant
• Low power consumption with 7000mAh replaceable battery

3. Operation Guide

3.1 NFC Configuration

EM310-UDL can be configured via NFC.

1. Download and install “Milesight ToolBox” App from Google Play or App Store.
2. Enable NFC on the smartphone and open "Milesight ToolBox" App.
3. Attach the smartphone with NFC area to the device to read the basic information. A diagram illustrates this process.
4. Basic information and settings of devices will be shown on ToolBox if it's recognized successfully. You can switch on/off the device by tapping the button on the Device Status. In order to protect the security of devices, password validation is required when configuring via unused phone. Default password is 123456.

5. Tap "Read" button to check current status and sensor data of device.
6. Tap "Write" button to write all your settings to the device.

Note:

• Ensure the location of smartphone NFC area and it's recommended to take off phone case.
• If the smartphone fails to read/write configurations via NFC, keep the phone away and back to try again.
• EM310-UDL can also be configured by dedicated NFC reader provided by Milesight IoT or you can configure it via TTL interface inside the device.

3.2 LoRaWAN Settings

LoRaWAN settings is used for configuring the transmission parameters in LoRaWAN® network.

Basic LoRaWAN Settings:

Go to Device → Setting → LoRaWAN Settings of ToolBox App to configure join type, App EUI, App Key and other information. You can also keep all settings by default.

Note:

• Please contact sales for device EUI list if there are many units.
• Please contact sales if you need random App keys before purchase.
• Select OTAA mode if you use Milesight IoT cloud to manage devices.
• Only OTAA mode supports rejoin mode.

LoRaWAN Frequency Settings:

Go to Setting → LoRaWAN Settings of ToolBox App to select supported frequency and select channels to send uplinks. Make sure the channels match the LoRaWAN® gateway.

* Support Frequency: AS923

Channels: 923.2, 923.4, 922.2, 922.4, 922.6

If frequency is one of CN470/AU915/US915, you can enter the index of the channel that you want to enable in the input box, making them separated by commas.

Examples:

• 1, 40: Enabling Channel 1 and Channel 40
• 1-40: Enabling Channel 1 to Channel 40
• 1-40, 60: Enabling Channel 1 to Channel 40 and Channel 60
• All: Enabling all channels
• Null: Indicates that all channels are disabled

3.3 Basic Settings

Go to "Device → Setting → General Settings of ToolBox App to change the reporting interval, etc.

Reporting Interval: 10 min

Tilt & Distance Switch: [Toggle Switch]

Change Password: [Input Field]

3.4 Advanced Settings

3.4.1 Calibration Settings

Go to Device → Setting → Calibration Settings of ToolBox App to enable calibration. EM310-UDL supports two calibration types:
