Country profile #

Timor-Leste, situated in Southeast Asia, boasts a tropical climate characterized by distinct wet and dry seasons. The wet season, occurring from November to April, aligns with the northeast monsoon and brings heavy rainfall and high humidity to the region. December and January witness the highest precipitation levels. Conversely, the dry season spans from May to October, coinciding with the southeast monsoon. During this period, Timor-Leste experiences lower rainfall and relatively cooler temperatures. The country’s coastal areas tend to be hotter than the interior due to the tempering effect of the ocean. Timor-Leste’s interior comprises mountainous terrain, where temperatures are cooler and rainfall is generally higher. Overall, the nation’s climate fosters lush greenery and agricultural productivity, but it also poses challenges such as the risk of flooding and occasional water scarcity.

Deployment outcomes #

A LoRaWAN gateway has been installed on the premises of the Ministry for Transportation of Timor-Leste.

Three meteorological instruments were installed close-by: an IoT MeteoHelix, an IoT MeteoWind, and a MeteoRain instrument which is connected to the MeteoHelix sends its data through it. This LoRaWAN weather station provides temperature, humidity, pressure, solar radiation, wind speed, wind direction and precipitation data. Each instrument delivers data packets in 10 minute intervals.

Data from Meteo Instruments #

Last readings pooled #

Here is an example panel with “last readings” collected from all instruments.

Some of the available data is not displayed in this panel for various reasons (for example the wind direction). We expect to maintain and improve the panel as we develop the database and visualization tools.

LoRa link health status #

Along with the meteorological payload, the gateway provides some information about the communications, which may be useful when troubleshooting the devices.

Availability and Access #

Data is made available in two formats: publicly available dashboards, or by subscription to relevant topics on the MQTT broker hosted at ICTP.

There are several methods for accessing the weather station’s output for custom usage:

• Using the publicly available Timor-Leste/Dili test station dashboard provided by ICTP:
  1. Place a link to the dashboard in your website like so:

     <a href="http://iot-ws.sti.ictp.it//dashboard/d/tls-test/test-station">Timor-Leste/Dili test station dashboard</a>

  2. This dashboard’s panels may be embedded in web applications using the iframe tag. Example:

     <iframe src="http://iot-ws.sti.ictp.it/dashboard/d/tls-test/test-station?viewPanel=2"
     	  width="100%" height="300" frameborder="0"></iframe>

     Insert this code snippet in your HTML document to replicate one of the panels on this page.
  3. Data for each panel is available in CSV format. To download it, go to the the panel of interest, then look for the inspect menu under its heading.
• Subscribe directly to the MQTT broker at ICTP (contact STI to request access); Note: It is up to the end user to retrieve and store data of interest.
