LEGION I.O.T
Connected sensors and devices that collect and exchange data in the physical world — the backbone of everything Legion I.O.T monitors.
The Internet of Things is the network of physical devices — sensors, appliances, vehicles, industrial equipment — embedded with the ability to collect and exchange data over the internet, without needing a person to operate them directly.
A typical IoT system follows four steps: sensors collect physical data (temperature, motion, location), a connectivity layer transmits it, cloud or edge software processes it, and an action is triggered — either automatically or by alerting a human.
Different devices use different radios depending on range and power needs: Wi-Fi and Bluetooth for short range, Zigbee and Z-Wave for smart-home mesh networks, LoRaWAN and NB-IoT for long-range low-power sensors, and 5G for high-bandwidth industrial use.
Matter is a newer cross-industry standard (backed by Apple, Google, Amazon, and Samsung SmartThings) designed to let smart-home devices from different brands work together over a shared local protocol, instead of each brand requiring its own app and hub.
Smart speakers, thermostats, doorbell cameras, and wearables make up the most visible layer of IoT — convenience devices that generate a constant stream of data about the home and the people in it.
Factories and utilities use sensor networks to monitor machine vibration, temperature, and output in real time, catching equipment failures before they happen (predictive maintenance) rather than fixing things after they break.
Wearables and remote patient-monitoring devices track vitals like heart rate and blood oxygen continuously, letting clinicians spot problems between appointments rather than only during them.
Many IoT devices ship with weak default passwords and rarely get security patches, making them an easy target — the 2016 Mirai botnet hijacked hundreds of thousands of cameras and routers this way to launch one of the largest DDoS attacks on record.
Rather than sending every bit of sensor data to the cloud and waiting for a response, edge computing processes data on or near the device itself — critical for applications like factory safety systems where a round-trip delay isn't acceptable.
