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.

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.
