Smart IoT System with Electrolysed Water for Healthier Plants

This innovation combines Electrolysed Water (EW) with an Internet of Things (IoT) system to improve vegetable health, optimise plant growth, and reduce algae without the use of chemicals.

Technology overview

This innovation combines Electrolysed Water (EW) with an Internet of Things (IoT) system to improve vegetable health, optimise plant growth, and reduce algae without the use of chemicals. Designed to replace traditional pH adjusters in hydroponics and aquaponics systems, the solution features a modular chamber setup, precise EW control, and real-time environmental monitoring. The technology addresses the common challenges of uneven plant growth, algae outbreaks, and chemical handling in urban agriculture. It is suitable for urban farms, vertical growers, educational institutions, and agri-tech solution providers.

Technology features

  • The Electrolysed Water (EW) system is capable of adjusting water pH levels from acidic to alkaline without chemicals.

  • An integrated IoT system with sensors for pH, EC, water temperature, humidity, light lux, CO₂, and atmospheric pressure.

  • Enhances germination and plant height of leafy greens, microgreens and algae significantly.

  • Five modular, human-sized growth chambers with protocols for immediate test-bedding and optimisation.

Potential applications

  • Urban farms and vertical farming systems.

  • Indoor hydroponics and aquaponics setups.

  • Algae control in closed-loop water systems.

  • Educational training for smart farming and sustainable agri-tech.

  • Food packaging films (for shelf-life extension studies).

  • Government agencies focusing on chemical reduction in agriculture.

Benefits

  • A chemical-free, safe alternative for pH control in agriculture.

  • The use of EW eliminates the need for acids or alkalis, reducing handling risks and removing the need for chemical storage.

  • IoT integration allows remote monitoring and automation, optimising plant conditions in real-time.

  • The system improves plant health, enhances yield, and controls algae naturally, providing a return on investment within the near term through savings on chemicals, training, and space.

Commercialisation

  • This technology is available for licensing and technology transfer.
