What is IoT (Internet of Things)?
Turkish: IoT
IoT connects sensors, machines, and devices to the internet so they can collect data, share status, and be managed remotely.
What Is IoT?
IoT (Internet of Things) is a network model where physical devices generate data through sensors, connectivity, and software, then send that data to digital systems. A temperature sensor, production machine, vehicle tracker, smart meter, or warehouse scanner can be an IoT component.
In a typical architecture, the device collects data, connects through a gateway when needed, sends data to the cloud through protocols such as MQTT or HTTP, and feeds dashboards, alerts, reports, or automation flows. In some systems, part of the decision-making happens near the device at the edge instead of waiting for the cloud.
Common Uses
Examples include machine downtime tracking in manufacturing, temperature monitoring in cold chains, vehicle location in logistics, soil moisture in agriculture, energy use in retail, and occupancy sensors in buildings. IoT connects physical operations to digital systems, changing how quickly teams can report and respond.
What to Watch
Device identity, secure connectivity, firmware updates, data volume, battery life, and field network quality should be planned early. MQTT is often used for lightweight messaging, while API design is needed when IoT data must be shared with external systems.
Related Terms
An API is a contract that lets software systems request approved data or actions from one another through documented endpoints.
MQTTMQTT is a lightweight publish-subscribe protocol that lets IoT devices exchange topic-based messages through a broker.
Time-Series DatabaseA time-series database optimizes storage, compression, and time-based queries for timestamped metrics, logs, and sensor data.
