Smart Sensors

What are smart sensors?

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.

The smart sensor is an analogue or digital converter combined with detection and calculation functions. It consists of converter components, electronic signal processing and processors, which contain some information in one package. This integrated sensor device, which has electronic components and transducers together on a Si wafer, is known as a chip system.

What functions do smart sensors have?

Smart sensors have intelligent functions such as wireless communication and are an integrated microcontroller. Used for analogue-to-digital conversion, digital processing, decision making, and two-way communication. Smart sensors offer various advantages over conventional sensors such as smaller size, minimal power consumption, and high performance.

Smart sensors allow for more accurate and automatic collection of environmental data with less noise under precise recorded information. This device is used to monitor and control mechanisms in various environments, including smart grids, battlefield reconnaissance, research, and various scientific applications.

Smart sensors form when micro-electromechanical system (MEMS) sensor elements are closely integrated with CMOS integrated circuits (ICs). These ICs provide device bias, signal amplification, and other signal processing functions. Originally, the wafer-level vacuum packaging (WLVP) technology used included only discrete sensor devices, and smart sensors were realized by connecting discrete MEMS chips to IC chips through the package or board substrate in an approach called multi-chip integration.

How do they work?

Applications developed by some country Instruments offer practical examples of smart sensors and how their components work together to produce useful information from measuring analogue currents and temperatures and to provide information for other functions mentioned. This application uses MSP430 MCU series variants with very low power consumption to make intelligent error display for power distribution networks.

When installed correctly, the error indicator reduces operating costs and downtime by providing information about failed network segments. At the same time, the device increases safety and reduces device damage by eliminating the need for dangerous diagnostic procedures. Because of its position, the error display is mainly battery-operated, so operation with low power consumption is also very desirable.

The error display mounted on the air duct connection points sends temperature and current measurements on the power cord wirelessly to the hub/terminal unit mounted on the poles. The hub uses a GSM modem to send data to the cellular network and to send real-time information to the master station. The master station can also monitor and run fault display diagnoses on the same data path.

If you have installed several smart home accessories and you think, "Everything is not too smart, is it?" You might be right. Using your smartphone and application to directly control the thermostat or turn off the lights makes life a little easier, but it's like a fantastic remote control. For truly smart home accessories that work on autopilot, you need to use smart sensors.

Think of sensors like the eyes, ears, and even the fingers of your house. You can see the state or condition of things in your home - when the door or window is open, when the room is hot or cold or the floor is wet or dry or when someone (or something) is moving - and then warns me him. Or (and this is where it gets very smart) you can set your smart sensor to tell other smart home accessories how to react.

What makes smart home accessories? Generally, it's defined by its ability to connect to a Wi-Fi network, allowing users to interact with it from their smartphones. Most of today's smart home accessories are also compatible with Amazon Alexa, the Google Assistant, Siri, or Samsung’s SmartThings platform.

In Future House Store, we’ve rounded up many endlessly useful smart home accessories.
