How to use ControlByWeb for greenhouse automation such as temperature and humidity monitoring, ventilation system control, and grow light control
An illustration of a ControlByWeb relay monitoring temperature and humidity in a greenhouse, controlling grow lights and ventilation, and sending data through a network.

With expandable I/O, on-board logic, and easy integration, micro PLCs are a great fit for IIoT applications like greenhouse monitoring and control.

Greenhouse automation systems are increasingly reliant on automation systems. With the growing demand for food, house plants, and cannabis, commercial greenhouses are turning to automation to improve quality and production. Reliable monitoring and control systems that can scale from small to large greenhouse structures are necessary. Features such as temperature, humidity, and soil moisture sensors, along with the ability to control fans, vents, and heaters, are essential for effective greenhouse automation.

Popular relays, like the ControlByWeb X-410™, simplify industrial applications like greenhouse automation without the need for coding.

X-418 Interface Screenshot

Programming a PLC is typically a specialized task requiring a skilled engineer who isn’t always available. Even so-called “easy-to-use” PLCs on the market require Ladder Logic, Function Block, or some kind of diagram building with complex code, scripts, and a mountain of settings. On top of all that, most PLC user interfaces are overloaded with options, menus, sub-menus, wizards, modals, etc.

Our no-code PLCs use a very simple user interface with an uncomplicated, single menu system on the left-hand side. Most users will simply start at the top section and fill in the fields as they move down.

Programming logic is one of the simplest tasks for our users. Choose between scheduled or conditional tasks and use drop-down menus to select options. These options are very straightforward, including turning relays on and off, sending email alerts, or logging a change under specific conditions.
