Smart sensors also play a key role in modern security systems.

This was once a manual process, but smart sensors can be used to automate process control. Smart sensors also enable process control, such as monitoring a process, like manufacturing an item, and making any adjustments that might be required to meet quality or production goals. They are very commonly used in industrial environments and are the driving force behind Industry 4.0.įactories often use smart temperature sensors to make sure machines aren't overheating, and vibration sensors to make sure machines aren't at risk of vibrating loose. There are countless use cases for smart sensors. This enables communication to external devices. Smart sensors also contain integrated communications capabilities that enable them to be connected to a private network or to the internet. A smart sensor has three components: a sensor that captures data, a microprocessor that computes on the output of the sensor via programming and communications capabilities. The compute resources must be an integral part of the physical design - a sensor that just sends its data along for remote processing isn't considered a smart sensor. At a minimum, a smart sensor is made of a sensor, a microprocessor and communication technology of some kind.
One implementation of smart sensors is as components of a wireless sensor and actuator network (WSAN) whose nodes can number in the thousands, each of which is connected with one or more other sensors and sensor hubs, as well as individual actuators.Ĭompute resources are typically provided by low-power mobile microprocessors. The smart sensor is also a crucial and integral element in the internet of things ( IoT), the increasingly prevalent environment in which almost anything imaginable can be outfitted with a unique identifier and the ability to transmit data over the internet or a similar network. These devices are used for monitoring and control mechanisms in a wide variety of environments including smart grids, battlefield reconnaissance, exploration and many science applications. Smart sensors enable more accurate and automated collection of environmental data with less erroneous noise amongst the accurately recorded information. A smart sensor is a device that takes input from the physical environment and uses built-in compute resources to perform predefined functions upon detection of specific input and then process data before passing it on.
