Current problems

Measuring by feel

"It's hot today" doesn't tell you the barn temperature or pond oxygen.

Too many sensors

Buying many without knowing where to place or read them.

How NextFarm solves it

One concrete answer per problem, and where to find it in the app.

In the app

Devices send readings to the app and web; control and alerts on your phone.

In the app

Ponds: low oxygen means an alert

DO, pH and water temperature on every pond; below threshold you get an alert and aerators start by rule.

Soil EC, moisture & temperature (3-in-1)

Soil — one in a representative zone

Substrate EC, moisture & temperature

Greenhouse substrate

Soil / substrate pH

pH 3–9, ±0.3

Air temperature & humidity

Greenhouses, barns

Light (lux)

0–200,000 lux, shading and lighting

CO₂

Pig and poultry houses — one per house

DO + ORP (dissolved oxygen)

Ponds, tanks — one each; low oxygen switches aerators on

What you can measure after a season

The software doesn't promise yields; it gives you numbers to compare before and after.

Hours above heat or below oxygen thresholds
