The Partnership Solution: Simplifying the Complex

After evaluating a number of commercial options, the UNE’s Applied Agricultural Remote Sensing Centre (AARSC) chose to work with Thinxtra and their solution partners, based on their IoT experience and proven IoT-enabled AgTech solutions, supporting the Thinxtra 0G Network, powered by Sigfox. The 0G Network is a low-cost, low-power, long-range wireless network designed to send or receive small messages, less than 15KB of data, between IoT devices. To date, the technology performs as a fit-for-purpose, end-to-end, low-cost solution that is fast and easy to deploy and delivers benefits to growers.

About The University of New England (UNE) and the Applied Agricultural Remote Sensing Centre (AARSC)

Formed in 1938, the UNE pioneered teaching external students by correspondence, making UNE Australia’s most experienced provider of distance, and now, online education. UNE’s Applied Agricultural Remote Sensing Centre (AARSC) specialises in research and development utilising remote sensing technologies to transform agricultural production systems and deliver measurable benefits to growers. AARSC collaborates extensively with researchers, industry, agricultural agencies, government and growers to bring technology capabilities together to meet industry priorities.

 

The UNE AARSC teams with industry, government, farmers and researchers to unlock the value of IoT-enabled insights for agriculture

In 2014, UNE partnered with industry bodies, government, researchers and farmers to launch a national research project focused on identifying optimal technologies (including remote sensing and IoT) to measure tree health and productivity in mango, banana, avocado and macadamia orchards, and to map all commercial orchards across Australia. The success of this collaborative project led to a second phase, beginning in 2019, that added citrus and olive orchards. One focus area is to improve water use efficiencies, motivated by recent drought.

We needed a robust, high-performance IoT solution that could save farmers the time needed to grab a shovel and drive long distances to manually check soil and tree conditions. IoT satellite connectivity offers some potential but was not yet commercially ready. The cost of cellular sensors, each with its own SIM card, rapidly became prohibitive considering the number of sensors we needed to deploy. A low-power, low-bandwidth, long-distance network solution was the only option that would meet our needs.

Our objectives were to provide the respective industries with validated, practical and affordable technologies, including satellite, airborne and ground-based sensing, that can measure tree health, productivity in terms of yield and quality, irrigation efficiencies, nutrition and the incidence of pest and disease. This research is also evaluating a range of commercially available IoT sensors and on-farm communication options that could better monitor the health and microclimates of individual trees. By integrating these highly complementary technologies the project team has made significant progress in identifying adoptable solutions to manage a range of constraints including water stress, critically important in a drying climate.

The journey to meet real-world farming IoT challenges

Based on previous experience, the UNE team anticipated some tough realities working with remote IoT-enabled sensor technologies in an agricultural environment. Sensors had to withstand harsh weather and damage by animals. Orchards are typically located in remote locations, which demand easily extended network coverage. Information from the sensors needed to be available remotely, as manual downloads and performing regular maintenance was not practical.


This project had some challenging requirements. We needed durable sensors to send data from underneath dense tree canopies over long distances, easy on-site configuration, low ongoing maintenance, particularly long battery life, and reliable automated delivery of data on an hourly basis. Because farms are in remote areas, often with no network coverage, we needed to create reliable long-range coverage on-site ourselves, quickly and easily, to connect many sensors across variable terrain. And we needed a cost-effective solution viable for growers to use long-term after the research phase ends.​

A fit-for-purpose solution for Agriculture

The UNE team chose Thinxtra, The IoT Telco, to architect a fit-for-purpose, end-to-end, low-cost solution that is fast and easy to install and maintain. Thinxtra’s proven expertise with mass IoT deployments and broad partner ecosystem gave UNE the opportunity to build an easily accessible, cost-effective, reliable, IoT solution to give information to growers in a useful format.

AARSC worked with Thinxtra to evaluate multiple sensors and nodes from different 0G solution providers, including Sensohive, Digital Matter and AxisTech. The researchers were also able to easily integrate sensors from other sources such as Edaphic and Enviropro. Typically, different solutions come with dedicated data platforms, so UNE created an end-to-end solution able to compile data from different sensors and map it to a central database for storage and online visualisation.

So far, research indicates IoT-enabled remote monitoring will deliver promising benefits for growers. We expect growers will have at least hourly access to specific data on tree health factors and irrigation to drive better decisions on farms. There is clear potential to save growers money and time because remote monitoring reduces the demands of manual crop management. We’re working closely with farmers to assure IoT solutions deliver the right insights to improve tree crop yield and productivity and are operationally viable for day-to-day work on remote farms.

Outcomes and next steps

The UNE research project into IoT technology for remote monitoring to better understand tree health, yield, productivity and irrigation will run for two full seasons before the outcomes are conclusive but the early results are encouraging for the AARSC team, including:

  • Quick access to usable data to support improved decision-making around tree health and irrigation management. 
  • The ability to simply and quickly deploy 0G LPWAN networks in remote locations where coverage is unavailable. 
  • Labour cost and time savings due to a reduced need to manually measure tree and soil conditions across expansive farms.
  • Information derived from sensor measurements across farms updated hourly online.
  • Insights that will drive improved productivity and profitability.

Including the UNE AARSC team, ten partner organisations joined the research project, funded by Horticulture Innovation Australia and the Australian Federal Government’s Rural Research and Development for Profit scheme

  • New South Wales Department of Primary Industries, 
  • Central Queensland University, 
  • Northern Territory Department of Primary Industry and Resources, 
  • Queensland Department of Agriculture and Fisheries, 
  • Citrus Australia, 
  • Australian Mango Industry Association, 
  • Australian Olive Association, 
  • Australian Macadamia Society, 
  • Tie-Up farming,
  • Ceres Imaging.
