1Introduction

This document describes the technical parameters and key functions which are connected

with customers’ applications, and it can help customers quickly understand the data format,

features, as well as other related information of IDUV915-LRW Inductive Sensor Endpoint.

2Product Concept

2.1 General Description

IDUV915-LRW Inductive Sensor Endpoint is a data acquisition and transmission terminal,

which is widely used in the intelligent construction of water meters, gas meters, and heat

meters. It can realize data collection, data storage management, abnormal warning and

wireless communication functions.

IDUV915-LRW based on a high performance LoRaWAN module, it supports standard

wireless LoRaWAN protocol.

IDUV915-LRW built-in high-performance non-magnetic metering module, can detect rotating

metal target in meters to measure the volume of flow. It is completely diamagnetic and has

strong anti-interference.

With pre-installed long-life battery and built-in antenna, the IDUV915-LRW has the

characteristics of simple deployment, high reliability, low power consumption and long

transmission distance.

2.2 Key Features

The following shows the key features of IDUV915-LRW.

Immunity of magnet interference.

Supports a range of event alarms including:battery life, reverse flow, Disassemble etc.

Waterproof: IP67.

Suitable to workin harsh environment.

Long range wireless data transmission.

Multi-band support, EU433, CN470, EU868, US915, AU915, IN865, etc.

Pre-installed long-life battery and built-in antenna.

Page 6/23

Air wireless configuration.

Firmware upgrade by FOTA.

Average life 10 years*.

Lifetime depends from the device location and reporting interval.

2.3 Curve freezing function introduction

The IDUV915-LRW also supports more flexible data collection point configuration.

Compared to the traditional recording method, the curve freezing function can help users

record the usage of each time period of the day and report the data.

In order to meet this demand, the IDUV915-LRW program will average 96 time points in a

day, and the interval between time points It is 15 minutes, as shown in the table below.

Table 2-1 Collection Point Settings for Default Curves

Curve reporting function has two reporting frame format, one is the default curve reporting

frame, its acquisition point settings such as Table 2-1. ( 4 am to 11 pm every 1hour. 11 pm to

4 am every 15 minutes)

The other is the user-defined curve reporting frame. The user can set any desired data

collection plan by modifying the 12-byte mask. The mask corresponding to the above figure

IDUV915-LRW Inductive Sensor Endpoint_User_Manual

Page 7/23

is FFFF8888888888888888888F. The mask can be obtained through the separately

provided data collection schedule.

Due to the limitation of the data length of the reported frame, a maximum of 77 data

collection points are currently supported. If the collection point set by the user

exceeds 77, the mask and AT command will not be displayed.
