The AgriHub360 Sensor is a solar-powered LoRa soil probe. It measures soil moisture, temperature, conductivity and pH, and sends readings to an AgriHub360 Hub, which posts them to the Device API.

The AgriHub360 Sensor: a probe in the soil, a solar panel and a LoRa antenna.

​
In The Field

Solar-powered and wireless. Push it into the ground and it reports over LoRa to the Hub. No mobile signal or WiFi is needed at the sensor. The probe and the solar-charged battery feed the radio, which uplinks every 15 minutes or slower. The Hub posts each reading on to the Device API, and the field timeline, alerts and models read from there.

​
Channels

The sensor also carries nutrient channels, ids 221 to 223 for nitrogen, phosphorus and potassium. They aren’t a supported reading. Don’t build on them.

​
Reporting Interval

The sensor reports every 15 minutes or slower. EU868 limits LoRa airtime to 1%, so a faster interval isn’t possible.

Channels, radio, power and mechanical specifications, in one sheet.

​
In The App

Each AgriHub360 Sensor is one device with its own id and API key. Claim it on your farm, assign it to a field, and readings appear on that field. A sensor that stops reporting is shown as stale rather than as a current value.

​
Open Design

The Sensor is built from commodity modules and nothing inside is sealed. Open Hardware lists the parts, what each repair needs and how to find a fault.
