Use cases

Scenarios of Implementation

Home automation

Hassle-free home automation with OTA updates

Do you have devices installed inside wall boxes controlling your home's lighting, temperature, and presence sensors? Implementing new features or fixing bugs in these devices typically requires updating their firmware. However, accessing these devices inside wall boxes can be difficult and time-consuming. With OTA updates, you no longer have to uninstall the devices or physically go to their location to update their firmware.

Gardening

Keep your plants always green from a remote location

Do you struggle to keep your plants green in a remote garden? With an Arduino Cloud-controlled system, automate watering using moisture sensors and a smart watering pump control device to ensure your plants receive the water they need to thrive. But what if you want to add new features or fix bugs in your system? Update your devices remotely through OTA updates for a convenient solution. With OTA updates, you can quickly ensure your system is always up-to-date and functioning optimally, no matter where you are.
