Product Introduction

Overview

EM310-UDL is a LoRaWAN

ultrasonic distance/level sensor mainly used for the detection of waste bin and another container level. With a compact size and wide measure range, EM310-UDL can be installed to any type of waste bins or container to monitor solid or liquid levels. besides, EM310-UDL equips with a 3-axis accelerometer to detect the status of the 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 the standard LoRaWAN ® protocol. LoRaWAN ® enables encrypted radio transmissions over long distances 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.
