Hydroponics System — full atmosphere and dosing control for soil-less farms

An STM32-controlled hydroponics rig that doses nutrient liquid, balances temperature and humidity, raises tickets like "low water level in line", reports by day, week or month, and stays connected even off-grid over GSM.

Inside the project

A farm that survives on dosing — automated

The dosing and greenhouse control experience, and the STM32 hardware managing the atmosphere.

01

Hardware engineering

Hydroponics hardware — STM32, humidity and temperature control, AC/DC power valves
STM32 controller with humidity and temperature control on an 8-layer PCB, switching 7 AC and 21 DC power valves to maintain the best atmosphere for plants.
02

Dosing & greenhouse control

Hydroponics solution — dosing liquid, atmosphere control, GSM connectivity, report generation
Dosing liquid under lab lights, a "Low Water Level In Line" ticket in progress, GSM-connected atmosphere control and day/week/month report generation for the whole greenhouse.

Scope of work

What the system can do

  • 01 Hardware Development
  • 02 Firmware Development
  • 03 Analytics Dashboard

Nutrient dosing

Precise dosing of liquid nutrients — the only thing a soil-less farm survives on.

Atmosphere control

Temperature and humidity balanced continuously for the best growing conditions.

Ticketing

Conditions like "low water level in line" raise a tracked ticket automatically.

GSM connectivity

Farms far from Wi-Fi stay connected and controllable over GSM.

Reports

Growth and system reports by day, week or month.

Valve control

7 AC and 21 DC power valves switched from one controller.
