Revision History

Product Introduction

1.1 Overview
EM310-TILT is a LoRaWAN® tilt sensor mainly for angle measurement and asset movement detection. With a compact size and 3-axis accelerometer, EM310-TILT can easily be installed on the objects to measure their X, Y, Z tilt angles. It can also detect the movement based on angle changes and send threshold alarms. It is equipped with NFC (Near Field Communication) and can easily be configured by a smartphone.
Sensor data are transmitted in real-time using the 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.

4. 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.

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: Indicating that all channels are disabled

Note:
For -868M model, the default frequency is EU868;
For -915M model, the default frequency is AU915.
3.3 Basic Settings
Go to “Device -> Setting -> General Settings” of ToolBox App to change the reporting interval, etc.

Default: 1080 mins, Range: 1-1080 mins
Change Password| Change the password for ToolBox App or software to access this device.

3.4 Threshold Settings
Go to “Device -> Setting -> Threshold Settings” of ToolBox App to enable the threshold settings and input the angle threshold. You can set a relative initial surface to measure the deviance from an initial one and if the device detects the angle of a certain axis reaches the threshold based on the initial position, it will upload the current data instantly.

position to measure the deflection angle.
Click “Clear” to change the initial position back to (0.00°, 0.00°, -90.00°).
Note: after writing “Setting” or “Clear” configuration, click “Read” to read the device to check if the initial position changes successfully.
Over / °| The maximum/upper limit of angle threshold.
Below / °| The minimum/lower limit of angle threshold.
Alarm Condition| Acceptable elements are “X”, “Y”, “Z”, “and”, “or” “only”, it takes 2 or 3 axes to complete an expression and the device will only read from left to right. If left blank, it will consider the condition as “or”.
Example:
1)    XandYorZ means (X and Y) or Z, that is XandY meets the threshold or Z meets the threshold.
2)    XorYandZ means (X or Y) and Z, that is XandZ meets the threshold or YorZ meets the threshold.
Alarm Reporting Interval| After the threshold is triggered, the device will detect if the threshold is triggered again according to this reporting interval.
---|---
Alarm Reporting Times| After the threshold is triggered, the device will detect according to Alarm Reporting Interval and if still triggered,  the device will send the certain number of alarms to NS.

Example:
When X axis is detected to 0° (0° – 1.91° = -1.91° < -1°), it will trigger the threshold and upload a alarm package right away. If it changes back to normal, the device will also upload a data package immediately; if not, it will send alarm package after 1 minute. This process will repeat 2 times.
