What is IoT?

The Internet of Things (IoT) refers to the billions of physical devices worldwide that are connected to the internet, collecting and sharing data. These devices range from simple sensors in a factory to smart home appliances, wearable fitness trackers, and connected vehicles.

IoT transforms ordinary objects into smart, data-generating assets. A sensor on a farming pump can report water usage. A Bluetooth-enabled Battery Management System (BMS) in an e-rickshaw can broadcast voltage and temperature. These devices use embedded processors, wireless protocols (Wi-Fi, BLE, Zigbee, LoRaWAN), and cloud platforms to create intelligent systems.

How IoT Works

1. Sensors and actuators collect data from the physical environment — temperature, motion, pressure, location
2. Connectivity transmits the data via protocols like Bluetooth Low Energy (BLE), Wi-Fi, cellular, or LPWAN
3. Edge or cloud processing analyses the data to derive insights or trigger actions
4. User interface displays information and allows control via dashboards, mobile apps, or automated workflows

IoT Applications in Indian Business

• EV fleet management — Real-time battery monitoring, geofencing, predictive maintenance
• Smart agriculture — Soil moisture sensors, automated irrigation, crop health monitoring
• Industrial IoT (IIoT) — Factory equipment monitoring, predictive maintenance, quality control
• Smart cities — Street lighting, waste management, traffic monitoring
• Healthcare — Remote patient monitoring, smart medical devices

Security Considerations

IoT devices are often deployed with weak security defaults — default passwords, unencrypted communication, and no authentication. The BAT BMS Bluetooth exploit is a textbook example. Secure IoT development requires encrypted communication, device authentication, regular firmware updates, and network segmentation.
