Manufactured by Milesight, this high-quality sensor provides highly accurate distance measurement for a variety of applications in harsh environments like flood monitoring, wastewater management, fill level monitoring in grains or fertilizer. The measurement is based on ultrasonic waves transmitted and reflected back from nearby objects.
Features
Measuring tank levels in industrial applications is a difficult task to carry out with repeated accuracy and reliability. We can continue to take use of the inexpensive traditional stick made of wood, metal or plastic and inspect it by our sense, but it’s labor cost and easy to error-making due to the manual reporting methods.
Ultra-low power consumption and easy deployment thanks to a built-in 19000 mAh high-capacity battery that can be used for 10 years. That is very important when you don't have access to remote places, for example, in cold winter. By leveraging LoRaWAN-based snow level monitoring solution, government departments can take timely response to heavy snowfalls and avoid confronting with long-time road restriction. The EM500-UDL ultrasonic distance level sensor can help create a network that helps improve field visibility and makes a city smarter.

Installation
For an optimal measurement and device maintenance over time, there are several mounting recommendations:
Ensure the location of EM500-UDL is within the communication range of LoRaWAN gateway.
Device must sit in a vertical position on top of the object and be fitted such that it has a clear path to the object.
Place device where it is far away the side-wall more than 30cm and without internal obstructions that block the ultrasonic signal. ( Position 1 )
Position 2 is the ideal location to install EM500-UDL.
Do not place device in the center of arched or circular container tops since it will cause multiple echos. ( Position 3 )
Do not place the device above the container inlet orifice. ( Position 4 )
For a complete list of mounting recommendations, please visit the frequently asked questions and discover the optimal setup details.
✅ Battery Connection and Sensor Activation
Open the unit removing the 4 screws.
Remove the plastic stripe on the left side of the battery labelled PULL.
Hold the power button for more than 3 seconds. The led should blink once.
In order to check if the sensor is ON, quickly press the power button. If the led blinks once, the unit is ON. If the led does not blink once, the unit is OFF.
For additional configuration of the EM500-UDL, please take a look to its user's manual.
Setup for Neuron
Setting up Milesight EM500-UDL in Neuron follows a standard procedure as with any other LoRaWAN sensor:
Login into Neuron.
Click Equipment option on the left menu. Select your existing LoRaWAN Gateway Protocol from the list.
Click on the LoRaWAN gateway you want to connect the sensor to.
Click on the Add button and select Sensor option.
Fill in the form with required data located in sensor's package label:
Name: Meaningful name. ( e.g.: SILO 1 SENSOR )
Serial number: SNxxxxxxxxxxxxxxxx ( label value )
Sensor type: EM500-UDL.
Device EUI: 24xxxxxxxxxxxxxx ( label value )
RF Region:
AS923_1 for Asia.
AU915 for Australia and Argentina.
EU868 for Europe.
US915 for America.
Activation Mode: OTAA_V_10X
AppEUI: 24E124C0002A0001 ( provided by Milesight )
AppKey: 572404C696E6B4C6F52613230313823 ( provided by Milesight )
Tags: Add some tags to facilitate the identification of the sensor.
Click on the Save button to complete the creation process. If the save button appears disabled, please check that all required fields are completed and dropdown lists have one item selected. You can identify required fields by an asterisk at the end of the name.
The new sensor appears in the list of the active sensors in that gateway. Review the information to verify all data is correct.
Congratulations! you have successfully added your LoRaWAN sensor to Neuron. Now you have to verify that the sensor battery is connected and the sensor is activated.
The last step to start ingesting data from the sensor is assigning a reading frequency to the sensor in Neuron. Click on the options icon ( three vertical dots ) of your recently added sensor and select frequency menu, then select your preference ( Second · Ten seconds · Minute · Hour · None ) in the submenu shown. Once assigned, data will appear in your asset, ready to be queried and analysed.
