01NUVON BY AGROSYSTEM
The station that measures your own field with Davis Instruments sensors and tells you on WhatsApp when you can spray, how much it rained and when the wind turned.
TRUST
37 years of precision agriculture, with in-house R&D and manufacturing.
Davis's exclusive partner in Brazil since 1998. Every Davis station that reaches a Brazilian grower goes through Agrosystem.
Certified equipment, with ISO 9001:2015 and CE marking.
02SPRAYING WINDOW
The answer is not in the forecast for the nearest town. It is in the wind, humidity and temperature measured inside your own field, at the minute the sprayer is about to go in.
Below 3 the air stalls and the droplet does not settle: that is thermal inversion, common at dawn and late afternoon. Above 10 the droplet leaves the target.
The hotter it is, the faster the droplet evaporates on its way to the leaf.
Dry air shortens the droplet's life. The mix concentrates before reaching the target.
Temperature minus dew point. It is the index that combines the two above and gives the real rate of evaporation. The platform computes it for you.
The exact range changes with the product, and the tool compares against the label of the pesticide you selected. In the Brazilian state of Rio Grande do Sul part of this is already a legal requirement: wind below 10 km/h, humidity above 55% and temperature below 30 °C.
THE SCALE THAT DECIDES
You pick the station and the pesticide. The tool compares current conditions with that product's ideal range and returns cleared or blocked, with the reason.
Wind speed and direction become an estimated drift distance and a score. You know whether the droplet reaches the neighbour, the riparian forest or the road.
Every application is stored together with the conditions at that moment. It is the record you need when someone asks under what conditions it was sprayed.
SPRAY DRONE
A drone flies low, with fine droplets and little spray volume. It is the method most affected by wind and dry air, and Brazil's MAPA Ordinance 298/2021 also requires a record of every application. Measuring in the field stops being a technical recommendation and becomes part of the operation.
03THE ALERT WHERE YOU DECIDE
96% of Brazilian farmers use WhatsApp as their main channel for deciding what to do in the field. Nuvon tells you there, not in an app someone has to remember to open.
Nuvon
Temperature, humidity, rain, wind, solar radiation, UV index and station offline. Plus two that warn before it happens: rain forecast and temperature forecast.
Operator, agronomist, manager. Each person follows the field they are responsible for.
It works on the device everyone on the farm already uses all day. The internet reaches 98% of Brazilian farms, in most cases only through a phone.
04UNIVERSAL CONNECTIVITY
Brazil's first universal connectivity module. Nuvon combines satellite, NB-IoT and Wi-Fi in a single device, so the data gets through from anywhere, even where there is no mobile signal.
05PROOF BEFORE YOU BUY
We are not asking you to take our word for it. See the real towers around your field on the map and the recommendation per carrier, using official Anatel data.
Coverage predicted from Anatel (SMP) licensed stations and real terrain (line of sight).
06DAVIS INSTRUMENTS PRECISION
Nuvon uses 100% Davis Instruments sensors, Agrosystem's exclusive partner since 1998. Data you can trust to decide.
WHAT IT MEASURES
Rain, wind, temperature,
humidity, radiation and soil.
Rainfall, wind speed and direction, air temperature and humidity, barometric pressure, solar and UV radiation, and soil moisture, depending on the version you choose.

NUVON MODULE
Board with connections labelled per sensor, SIM chip, lithium-ion battery and Anatel certification. Sealed enclosure built for the field.
AUTONOMY
A 10W solar panel and two lithium-ion batteries keep it running even through long spells without sun.
07GEOLOCATED FORECAST
Nuvon uses the forecast from meteoblue, of Switzerland, which combines more than 30 weather models with artificial intelligence. And it does what no generic forecast does: it corrects that result with what your own station is measuring in the field.
The global model gets the pattern right but the detail wrong: the lowland that traps the cold, the hill that deflects the wind, the field sitting 40 km from the nearest official station. Nuvon compares the forecast against what your station actually measured and corrects the systematic bias at that spot.
The correction learns from history. Every week of measurement improves the fit for your coordinates, so the forecast for your farm gets more accurate over time, something a portal forecast never does.
The next 24 hours hour by hour and 14 days ahead, at your field's coordinates, with rain and temperature forecast alerts straight to WhatsApp.
In the comparison meteoblue itself published across 475 stations, the model came first at the 12 hour horizon and among the top two at 24 hours, ahead of models from ECMWF, NOAA, DWD, Météo-France and the UK Met Office.
08PLATFORM AND APP
Use it from your computer or the app (Android and iOS). Geolocated forecast, spraying window, alerts and an open API.




Forget the forecast for the nearest town. Nuvon combines the real measurements from your station with weather models to deliver the forecast for the exact coordinates of your crop.
Feed the data into ERPs, farm platforms, BI and your own software. Standardised, accessible and scalable.
From simple rainfall measurement to a complete agrometeorological station.

09WHO MAKES NUVON
Agrosystem does its own research, development and manufacturing. Nuvon is part of that experience in precision agriculture, built since 1989.
About Agrosystem ↗Ten times the INMET public automatic network, which has around 500 stations for the whole of Brazil.
Consultants and technical support in every region.
10AFTER-SALES
A station that is down means lost data, and lost data cannot be recovered later. That is why Agrosystem monitors the health of every station in real time, and does not wait for your call to act.
The console tracks battery charge, signal quality and whether the station is sending data. When something goes out of range, it enters the incident queue.
Most support starts with Agrosystem calling the customer, not the other way round. That is active after-sales, and it is what makes us the best support operation in precision agriculture in Brazil.
When you need someone in the field, someone is nearby. Consultants and technical support in every region of the country.
11BEFORE YOU INSTALL
Yes. Besides NB-IoT and Wi-Fi, Nuvon has satellite connectivity (the GlobalStar network), which does not depend on mobile towers. Use the coverage map above to check your own farm.
Depending on the version: rain, wind speed and direction, air temperature and humidity, barometric pressure, solar and UV radiation, and soil moisture. All with Davis Instruments sensors.
No. Nuvon is self-powered: the solar panel charges two lithium-ion batteries, keeping it running continuously.
No. It is done in simple steps, from the mast to the sensors, guided by the technical team. See the video on this page.
