LGT92 LoRaWAN GPS and Motion Tracker

The Dragino LGT92 LoRaWAN GPS tracker offers a low power GPS module combined with a 9-axis MEMS sensor (accelerator, gyroscope and compass). Its primary function is to provide motion detection and up-link the current GPS positions. It also has a emergency button that will immediately force an up-link when pressed. The power for both the GPS module and MEMS sensor are controlled by the MCU to achieve the best energy profile, but the power settings are user configurable.

Telemetry2U has a live demo of a Dragino LGT92 GPS and Motion Sensor running on our IoT Platform.

The LoRa wireless technology used in the Dragino LGH92 allows users to send data and reach extremely long ranges at low data-rates. It provides spread spectrum communication and high interference immunity whilst minimising power consumption. It is well suited for asset security and usage tracking.

The Dragino LGH92 has a rechargeable 1000mA Lithium-Ion battery and can be charged with a standard micro USB cable.  The USB cable is also used to configure the device's settings via AT commands. The Dragino LGH92 is pre-programmed to detect movement, with a variable threshold. When static the Dragino LGH92 sends location data every hour (keep-alive-time). While in motion, the Dragino LGH92 will upload its location information at 1-minute intervals (transmit time). The device will switch to static mode if no movement is detected for 5 minutes, saving on battery life. The data records include the battery voltage, motion status, GPS lat/long coordinates and the alarm status, with the pitch/roll being optional.

If the emergency button is held down for more than 5 seconds, the Dragino LGH92 will enter alarm mode and will immediately send an uplink, followed with an uplink every 60 seconds, for 60 records.  During this time, the alarm flag will be active meaning it can be used to trigger an email/SMS or voice alert from the server end.

The Dragino LGT92 also has an LED to indicate its status.  The LED colours are explained below.

Power On:GREEN LED on for 2 seconds
Join Request:BLUE LED fast blink once (200ms)
Join Success:PURPLE LED on for 1 second
Fixing Location:GREEN LED blinks 200ms per second
Fixed and Uplink:BLUE LED blinks twice (200ms/blink)
Fail Fix and Uplink:RED LED blinks twice (200ms/blink)
Enter Alarm Mode:RED LED on for five seconds
Uplink under Alarm:RED LED on for one second
Exit Alarm:BLUE LED on for one second
Downlink ReceivedGREEN LED on for 1 second
Movement Detect:RED LED on for 500ms

 

The LGT92 LoRaWAN GPS tracker combined with Telemetry2U ticks all the boxes when it comes to personnel and mobile asset management.

  1. You can see your asset’s real-time location on a live dashboard that links to Google Maps.
  2. GPS data is uploaded every minute when your assets are on the move and once every hour when stationary so you can see exactly where they've been and how long they have been there for.
  3. It immediately sends an uplink when motion or vibration is detected and that can effectively be used to trigger an alert from Telemetry2U’s IoT Platform to let you know work has started your equipment is being tampered with.
  4. The 9-axis Accelerometer data is sent with every uplink and shows what angle your equipment is on. You can trigger an alert if the angle goes past your limits - perfect for rollover detection on farms and other worksites.
  5. It’s fitted with an emergency push button that immediately triggers an E-mail, SMS, or voice call from Telemetry2U when pressed. This helps keep you operators and personnel safer.

***** Optional T2U Licence *****

To ensure Telemetry2U can make IoT technology available to everyone, we offer a couple of checkout options when purchasing LoRaWAN gateways and nodes.

  1. Buy hardware from us without a T2U licence and the items will be shipped with the factory firmware/settings leaving the configuration and network server connection to you, the end-user. Get started quickly with a 14-day free trial on Telemetry2U's sophisitcated IoT Platform and later build a custom subscription plan, perfectly tailored to your monitoring and control requirements. This option is perfect for DIY users who are familiar with LoRaWAN technology but like the concept of a complete, all-in-one IoT solution.
  2. Alternatively, purchase hardware from us with a once off T2U licence and choose from one of our bundled server plans. Hardware will be shipped pre-configured, loaded with the latest firmware, and ready to plug-and-play. All you’ll need to do is plug in your gateway, install your end-devices and your practically ready to go. No technical background or programming tools required. It doesn't get any easier.

If you have any questions about how Telemetry2U can help you get your world on the IoT cloud, please get in touch with us today, we're here to help.
