by Tutorial45

The world currently makes use of approximately 30 billion IoT devices to build a more interconnected world where information sharing and automation is done with ease. Although a large percentage of available IoT devices are deployed across commercial facilities, the use of IoT for home automation in domestic spaces is at an all-time high.

IoT devices and home automation software serve as the foundation for this growth. These tools are used to automate room temperature, control window blinds, and lighting. IoT can also be deployed for more complex projects such as watering and timing the watering of flowers or in-door plants. You can also choose to stretch the limit of your home automation project by developing an advanced digital home assistant to help you with tasks. But before delving into advanced projects, here are 21 IoT projects you can start with to get a feel of what can be accomplished.
