1. Product Introduction
1.1 Overview
AM300 series is a compact indoor ambience monitoring sensor including motion, humidity,
temperature, light, TVOC, CO2, HCHO/O3level, barometric pressure and PM2.5 & PM10 for
wireless LoRa network. It is equipped with NFC (Near Field Communication) and can easily be
configured via 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.
