You don't pay anything now. We first talk with you, understand what you need and agree a contract.
The SmartSoil 8-in-1 Soil Sensor turns a soil test into a ten-second job. Push the probe into the ground and read pH, nitrogen, phosphorus, potassium, electrical conductivity, moisture, salinity, temperature, organic matter and calcium — then let the Famo AI app turn the numbers into a fertiliser and crop plan in the farmer's own language.
It was designed by our team together with our manufacturing partner in Beijing, so hardware and software fit together from day one. Bluetooth and USB-C connect it to the app, an IP68 body survives rain and mud, and each test costs a fraction of a laboratory analysis.
Ideal for: agronomy service providers, cooperatives, input retailers, government extension programmes and farm-technology distributors.
