EM400-TLD - ToF Laser Distance Sensor

The EM400-TLD is a distance sensor based on ToF (Time of Flight) technology, designed for detecting fill level and position status. With a detection range of 2 to 350 cm and minimal blind zone, it is particularly suitable for monitoring waste bins, containers, and various distance measurement applications. The device features dual 9000 mAh replaceable batteries providing up to 10 years of operation, IP67 protection rating, and NFC configuration capabilities.

Thinger.io Integration

Requirements

A LoRaWAN server is required to communicate the Milesight EM400-TLD into Thinger.io, some options are:

Alongside, the corresponding plugin for the selected LoRaWAN server needs to be installed in your Thinger.io instance.

Get Started

Installation

Look for the plugin in the Thinger.io Plugin Store and install it in your Thinger.io instance. Once the plugin is installed a new Product will be created for this device.

Configuration

The Product is already preconfigured, check that the auto provision prefix matches the one selected in your LoRaWAN server plugin in Thinger.io, or change it to your desire.

Usage

Start sending uplinks for autoprovisioning devices and buckets. This product also provides a predefined dashboard and downlinks.
