Greenhouse wireless
environmental sensing
Sense-i nodes measure temperature and humidity in each crop zone of a greenhouse or polyhouse, so growers see the hot end, the cold corner and the humid bay that a single climate sensor misses.
THE PROBLEM
One climate sensor cannot describe a whole greenhouse
Most greenhouse controllers run from one or two sensors in a central box. Real houses vary: the end near the fan wall runs cooler than the far end, bays near the doors swing with outside air, and humid pockets form in dense canopy where air movement is poor.
Those differences matter to the crop. Hours of high relative humidity with leaves near dew point drive fungal disease. Heat stress at the far end cuts fruit set. Without zone data, growers either over-ventilate the whole house or accept losses in parts of it.
Greenhouses are also hard places for wiring: wet, under irrigation, with crops replanted and structures reconfigured each season.
HOW WE SET IT UP
Sensing by crop zone
Zones drawn with the grower
We agree zones by crop, bay and airflow pattern: near the pad and fan walls, the centre, the far end, the door bays. One node per zone at crop height, more in large or mixed houses.
Mounting that moves with the season
Battery nodes mount on posts or structure and can be moved when the layout changes. Setup and re-zoning are done from a phone over BLE.
Alerts growers act on
Alerts for frost risk at night, heat stress in the afternoon and long periods of high humidity go to the grower by WhatsApp, SMS or call.
Room to grow the sensing
CO2, soil moisture and other parameters are added as new sensing modules, developed for the project and reporting into the same dashboard.

FAQ
Questions buyers ask us
How many sensors does a greenhouse need?
At least one per climate zone at crop height. A typical house has distinct zones near the cooling pads, the fans, the centre and the doors. Large or multi-crop houses need more. We set the count with the grower during the survey.
Can wireless sensors survive greenhouse humidity?
Yes, in an enclosure chosen for the environment and placed out of direct irrigation spray. Sense-i nodes come in plastic, metal or custom enclosures, and we pick the one that suits your houses.
Can I add CO2 and soil moisture later?
Yes. CO2 and soil sensing are developed as additional modules, reporting into the same platform and dashboard as the temperature and humidity nodes.
Can the sensors control fans or misters?
The nodes have relay and control-signal outputs and run thresholds locally, so they can switch a fan or mister. For a full climate control loop, we design it with your existing greenhouse controller.
Growing across several houses or sites?
Tell us the crops, the house sizes and how they are cooled. We will propose zones, nodes and a radio plan.
