sensor data
what is sensor data
Sensor data is the output of a device that detects and responds to some type of input from the physical environment.
Sensor data is an integral component of the internet of things (IoT) and edge computing environments and initiatives.
in IoT, almost any entity imaginable can be outfitted with a unique identifier and the capacity to transfer data over a network
Sensors can be instrumented to track a variety of data points, but the most common include temperature, humidity, pressure, proximity, speed, rotation, light, and gas or chemical levels.
how does it work
Sensor data is generated when a device detects and responds to some type of input from the physical environment. Often coming together in a network, sensors generate mass quantities of sensor data that may or may not be immediately useful for decision-makers.
The sensor just needs to connect to a mobile phone instead of connecting directly to a Wi-Fi router. The main reason for this is to allow the mobile-phone user to interact directly with the sensor before sending the information up to the cloud. These applications are served by the Bluetooth standard, created in 1998.
Sensor data can either be stored local to the sensor node that collected the data (local storage), transmitted to one or more collection points outside of the sensor network (external storage), or transmitted and stored at other nodes in the sensor network (in-network storage).
Sensors gather and generate information based on the physical conditions surrounding them. Sensors usually include the following
a processor to convert physical signals into digital data
communications capabilities to transmit data to people or machines
and use a power source.
