1. Product Introduction 1.1 Overview EM400-TLD is a LoRaWAN® distance sensor based on ToF (time of flight), which is mainly used for detecting the fill level and position status. With an appropriate FOV with the maximum field angle of 27°, it has almost no blind spot when installed on small-sized waste bins or containers. The embedded temperature sensor enables it to monitor whether the containers are burning for security reasons.

Parameters Device EUI App EUI Application Port Join Type Description Unique ID of the device which can also be found on the label. Default App EUI is 24E124C0002A0001. The port used for sending and receiving data, default port is 85. OTAA and ABP mode are available. Application Key Appkey for OTAA mode, default is 5572404C696E6B4C6F52613230313823. Device Address DevAddr for ABP mode, default is the 5th to 12th digits of SN.
LoRaWAN Frequency Settings: Go to Setting > LoRaWAN Settings 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.
3.3 Basic Settings Go to Device > Setting > General Settings to change the reporting interval, etc. Parameters Device Mode Description Select from “Standard Mode” or “Bin Mode”. Reporting interval of transmitting data to network server. Reporting Interval Standard Mode: 10 minutes as default; Bin mode: 20 minutes as default. Enable or disable the installation height of the device when in Bin Mode. Note: Installation Height 1.
Parameters Collecting Interval Threshold Dismiss Report Description Collecting interval of ToF sensor to detect distance. The default value for standard mode is 10 minutes, for bin mode is 20 minutes. When the collected value changes from outside the threshold to within the threshold, a threshold dismiss packet will be reported. 3.5 Maintenance 3.5.1 Upgrade 1. Download firmware from Milesight website to your smartphone. 2.
3.5.2 Backup EM400-TLD support configuration backup for easy and quick device configuration in bulk. Backup is allowed only for devices with the same model and LoRaWAN® frequency band. 1. Go to Template page on the App and save current settings as a template. You can also edit the template file. 2. Select one template file which saved in the smartphone and click Write, then attach to another device to write configuration. Note: Slide the template item left to edit or delete the template.
area to device to complete reset. 4. Installation 1. Drill two holes on the container cover according to the location of device mounting holes. 2. Put the device under container cover and align the holes in order to perfectly screw the bolts into the holes from the other side of the cover. Besides, the device can also be fixed by two M4 mounting screws and wall plugs.
Installation Note: In order to provide the best data transmission, please ensure the device is within the signal range of the LoRaWAN® gateway and keep it away from metal objects and obstacles. Avoid strong light, like direct sunlight or IR LED, in the detection area. Do not install the device close to glass or mirror. After installation and adjustment, please remove the protective film. Do no touch the lens of sensor directly to avoid leaving the fingerprint on it.
