Product Introduction

Overview
EM500 series is a sensor mainly used for outdoor environment through wireless LoRa network. EM500 device is battery powered and designed for multiple mounting ways. It is equipped with NFC (Near Field Communication) and can easily be configured by a smartphone or a PC software.
Sensor data are transmitted in real-time using 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.

Features

  • Up to 11km communication range
  • Easy configuration via NFC
  • Standard LoRaWAN® support
  • Milesight IoT Cloud compliant
  • Low power consumption with 19000mAh replaceable battery

Hardware Introduction
