Concept by Francesco Giambuzzi. IoT consulting by Mattia Sica with ASTRAL3D.
In progress · 2026
Francesco Giambuzzi conceived RADA around the work of farms and agricultural consortia. He asked me to advise on collecting data in the field. With ASTRAL3D, I built the sensor nodes, gateways and communication protocols. I also worked on part of the data storage and visualisation.
An unexpected reading can reflect conditions in the field, rain or the sensor itself. I worked on calibration before interpreting the data. When choosing components I had to balance cost, battery draw and what the solar panel could put back.
With LoRa, a transmission that reaches farther can keep the channel busy for longer. I designed the protocol around the trade-offs between spreading factor, packet size, retries and quiet periods. To timestamp readings I consider GPS time and, when it is unavailable, a reference obtained through the gateway.
Francesco’s design calls for servers at the farms. I used Google Cloud to validate the component I developed. Readings received from the gateway were stored and could be viewed in a React dashboard with access controlled by IAM.
From data to interpretation: the stages of the project.
RADA took me across electronics and software. A usable measurement also depends on calibration, power and communications. I now consider those constraints together when designing how data moves through a system.
The component developed with ASTRAL3D is a prototype undergoing validation.
