Know your soil before it's too late.
GreenGo watches soil moisture, temperature and humidity every 10 seconds, texts you when the soil runs dry, and lets you switch the pump on from anywhere.

See the soil, not just guess
A sensor in the ground reports moisture, temperature and humidity every 10 seconds — day and night, whether or not you're at the farm.
Get texted when it matters
No app to check obsessively. When soil drops below your threshold, GreenGo sends an SMS — even on 3G, even with no data plan.
Turn the pump on from anywhere
Switch irrigation on remotely, or let the device handle it automatically — a physical switch on site always has the final say.
How it works
Device → readings → alert → pump.
01
Sensor reads the soil
A probe in the ground measures moisture every 10 seconds, alongside air temperature and humidity.
02
Readings reach GreenGo
The device sends each reading to your dashboard — and to its own LCD screen in the greenhouse.
03
You get an SMS if it's dry
Soil below your threshold triggers a text, sent from GREENGO, with the reading and time.
04
Turn on the pump
Reply from the dashboard, or let AUTO mode handle it — the physical switch on site always overrides remote control.
The same instrument, two surfaces
The bar on your phone is the bar on the LCD in the greenhouse.
GreenGo's device draws its readings as blocky bar graphs on a 20×4 character screen — the same shape the farmer sees standing next to the crop. We didn't design a new chart for the app. We redrew the one that's already there, so both surfaces read as one product.
