A more simplistic way to explain M2M communications is that it can only occur when a sensor, or any other device, is connected to a machine. It is then possible to capture an event that is transmitted over a network and also deliver data to applications.
These smart sensors include a SIM card that receives and conveys the data wirelessly to a central server. Here an Application translates the data into information that can be studied and actioned. For example, if the temperature is too hot, it can be altered and turned down.
The machine captures events such as altitude, speed, heart rate, stress levels, light, movement, location and more, as they’re embedded into a remote asset.
