Data is necessary for IoT, and sensors are an important factor to ensure the accuracy and credibility of data. This essential layer consists of physical, micro appliances, embedded in an IoT device, which are responsible for collecting data or controlling a mechanism.
Sensors: Sensors work to gather small data from the surrounding environment. This allows an IoT device to capture relevant data for real-time or post-processing.
Depending on the type of sensor, this small piece of hardware can measure absolutely anything. This can be smoke, motion or even blood pressure.
While advanced sensors can measure a range of complexities, some IoT devices have multiple sensors bundled to be able to collect a range of data or perform multiple functions.
Our smartphones for example have GPS, fingerprint, camera, tilt, motion and numerous other sensors, all bundled in one.
