The range of sensors from Netshield include active -, digital- and analog sensors that will detect and respond to some type of input from the physical environment. This include detection of light, heat, motion, moisture, pressure, or any one of a great number of other environmental phenomena.
Active and passive sensing technologies are both used in remote sensing to make observations and measurements from a distance or on a scale beyond those observable to the naked eye. Sensors can also be used in harsh environments and places that are inaccessible to people. Active sensors are also widely used in manufacturing and networking environments for example to monitor industrial machines or data center infrastructure so anomalies can be detected and components can be repaired or replaced before they break and shut everything down.
There are various types of analog sensors; practical examples of various types of analog sensors are as follows: accelerometers, pressure sensors, light sensors, sound sensors, temperature sensors, and so on. Electronic sensors or electrochemical sensors in which data conversion and data transmission takes place digitally are called as digital sensors.
