AI in IoT refers to combining Artificial Intelligence (AI) with the Internet of Things (IoT) to make connected devices smarter and more efficient. IoT devices collect massive amounts of data from sensors, machines, and users. AI processes that data, identifies patterns, and makes real-time decisions without human help. This integration enables systems to learn, predict issues, and act instantly. AI in IoT improves automation, reduces manual work, and increases accuracy in everything from smart homes to industrial machines.
