JPiOT / Hydroponic System

A connected viewof your growing environment.

Monitor the air and nutrient solution, manage dosing, and coordinate supported pumps, lighting and ventilation from one hydroponic control system.

Overview

One system, three jobs.

In an indoor farm, every condition the crop meets is one somebody set. This system reads those conditions, can act on them within the limits it is configured with, and shows you what is happening.

  1. 01

    Monitor

    Light, air temperature, humidity and CO₂ in the growing area; pH, EC and temperature in the nutrient solution.

  2. 02

    Automate

    Within the configured logic, it can run the dosing pumps, the circulation pump, the grow lights and the fan connected to it.

  3. 03

    Review

    A 7-inch touchscreen on the controller, plus remote monitoring and Telegram where configured.

What it can operate and what is supplied are two different lists; the second one is your quotation.

Monitoring

Understand the room. Understand the feed.

Two groups of readings, taken in two different places in the same growing system.

A drawing of the growing area: grow lights above the growing channels, a fan, and the environment sensor unit hanging in the room.Grow lightsGrowing channels

01Environment: the air around the crop

Light intensitylux
How bright the growing area is, read in lux in the product materials. Lux describes light as the human eye sees it; it is not PPFD, the light measure used for photosynthesis, and converting between them needs information about the light source.
Air temperature°C
The air around the crop, so you can see how warm the room runs through the day.
Humidity%
How much moisture the air holds, read as relative humidity.
Carbon dioxideppm
The CO₂ level in the air of the growing area. The reading shows the level; it does not mean CO₂ injection is installed.
VPDderived
Vapour pressure deficit, worked out from air temperature and humidity rather than measured by a sensor of its own. It summarises how “drying” the air feels to the plant.

02Nutrient solution: the feed that reaches the roots

pHacidity
How acidic or alkaline the solution is, which affects how available the nutrients are to the roots.
ECµS/cm
Electrical conductivity: it rises with the dissolved salts in the solution, so it indicates overall strength. It does not measure each nutrient separately.
Solution temperature°C
How warm the solution in the reservoir is. Monitoring it does not imply a chiller or heater is part of the system.

Any example readings on this page are examples only. The right values for your farm depend on the crop, its stage and your growing method.

Measuring is not controlling. A reading tells you the condition. What the system does about it depends on the equipment connected and the logic configured for your installation.

Automation

From a reading to a controlled response.

Choose a step. The schematic highlights the parts involved and says what happens there.

Illustrative system flow · recirculating arrangement

1 Sensors readEnvironment sensors in the growing area read light, air temperature, humidity and CO₂, while probes in the reservoir read the solution’s pH, EC and temperature.

2 Controller receivesThose readings arrive at the JPiOT controller, which shows them on the touchscreen and, where configured, passes them on for remote monitoring.

3 Logic checksThe controller compares the readings with the targets and rules configured for your crop and installation. There is no universal setting: those values are set when the system is set up.

4 Equipment respondsWithin that logic, the controller can run the fertiliser A and B dosing pumps, pH-up or pH-down dosing as the reading calls for, the circulation pump, the grow lights and the fan — as far as the equipment connected at your installation allows.

5 Monitored againThe solution returns to the reservoir and the sensors read the new conditions, so the same loop runs again.

Hydroponic system flow: illustrative schematicAn illustrative recirculating arrangement. Environment sensors read light, air temperature, humidity and carbon dioxide in the growing area, and probes in the nutrient reservoir read pH, EC and solution temperature. The readings go to the JPiOT controller, which, following its configured logic, can operate the fertiliser A and B dosing pumps, the pH-up and pH-down dosing pumps, the circulation pump, the grow lights and the ventilation fan. Solution is pumped from the reservoir through the growing channels and returns to the reservoir, and the sensors read the new conditions.JPiOT controllerECpHLED grow lightsGrowing channelsFan /ventilationLightAir tempHumidityCO₂VPD (derived)Nutrient reservoirpHEC°CABpH+pH−Dosing channelspH up or down,only as neededCirculation pumpReturn to the reservoir Hydroponic system flow: illustrative schematicAn illustrative recirculating arrangement.

Electrical specifications. Relay counts, electrical ratings, supported loads and enclosure ratings are not published here. Ask for the specification of the configuration you are quoted.

MeasureBeforeAfter
Harvest cycle Before31 days After26 days

Total across seven tables Before406 kg After546 kg

Calculated from the figures above: a 5-day shorter cycle, 20 kg more per table, and 140 kg more across seven tables.

The document also describes the plants in the after condition as fresher, more uniform and larger, with less yellowing, and states that 15% more fertiliser was used in that condition.

These are results reported in the project document supplied to us, for one growing operation. They are not an independently validated controlled trial and not a guarantee: outcomes depend on the crop, the growing conditions, how the system is operated and how it is installed.

What it watches

A living view of the farm.

Follow the latest readings from our connected farm sensors.

Values appear as each sensor reports them, except weight: shown in kilograms, with a reading below zero as 0 kg.

Weight scale

Straight from the scale.

The newest reading from the weighing scale on the farm above, on its own. A scale weighs everything on its platform together: in a growing setup, the container, medium, crop and the water the medium holds, so watering raises the reading and drying brings it down.
