Version：1.0

1. Overview

The LPMS-IG1W, a 9-axis IMU sensor, detects orientation and acceleration with high precision. This device communicates with host systems such as PCs and smartphones via Wi-Fi connection. Despite its compact size, it offers high accuracy, IP67 waterproof protection, and is equipped with a powerful onboard CPU that processes gyro, accelerometer, and magnetometer data, providing low-drift and high-precision results in real-time. It is well-suited for industrial environments where high accuracy and low latency measurements are required.

Features

• MEMS-based 9-axis IMU with sensor fusion technology

• Low-noise, low-drift accelerometer (4°/1h)

• Dual gyroscopes enabling a wide measurement range (400–2000°/s)

• Real-time computation of orientation and linear acceleration within the sensor

• Wi-Fi connectivity

• Waterproof design (IP67) with impact resistance up to 10,000G

2. Quick Start Guide

2.1 Network Connection Setup

To connect this device to Wi-Fi, you first need to set up the network connection. To do this, access the device from a Wi-Fi-enabled smartphone or PC. Below is an example of the setup process using an iPhone.

For iPhone Users

Please follow the steps below to set up the network connection:

• Connect the LPMS-IG1W to a power source using the included USB cable (the sensor will power on automatically).

• On your iPhone, go to the list of available Wi-Fi networks and select the Wi-Fi SSID printed on the sensor.

• Enter the default password "12345678" and connect.

• You will be automatically redirected to the Wi-Fi portal page.

Open

Wi-Fi connection list

• On the Wi-Fi portal page, tap the menu button in the top left corner and select Wi-Fi Manager.

• Tap the Scan button to search for available Wi-Fi networks. A list of nearby Wi-Fi networks will be displayed. Select the desired Wi-Fi network and tap Join to connect.

• Once the connection is complete, the IP address will be displayed at the top of the Wi-Fi list. Make sure to note it down.

• From another device on the same network, open a web browser and enter the previously displayed IP address.

• Confirm that you can access the same Wi-Fi portal page as before.

2.2 Data Acquisition

2.2.1 LpmsControl

You can check the data from LPMS-IG1W using the LpmsControl software.

• On a device connected to the same network as the LPMS-IG1W, launch LpmsControl (version 2.1.5 or later).

• Enter the IP address and port number of LPMS-IG1W (these can be found on the Wi-Fi portal page > Wi-Fi Status screen).

• Click the Connect button to establish a connection with the sensor.

2.2.2 Socket Communication and MQTT Communication

The LPMS-IG1W can transmit data over Wi-Fi using two different methods: Socket Communication Mode and MQTT Communication Mode.

Socket Communication Mode

In Socket Communication Mode, the LPMS-IG1W operates as a socket server for communication.

• Access the settings page by navigating to Wi-Fi Portal Page > Menu (top left) > Settings.

• Ensure that the Mode is set to Socket Server and specify the server port for connection.

• Sensor data will be transmitted to the specified server.

MQTT Communication Mode

In MQTT Communication Mode, the LPMS-IG1W operates as an MQTT client for communication.

• Access the settings page by navigating to Wi-Fi Portal Page > Menu (top left) > Settings.

• Change the Mode to MQTT Client and specify the target MQTT server.

• Sensor data will be transmitted to the specified MQTT server.
