Different Types of Smart Sensors

Applied Tech Review | Thursday, September 02, 2021

There are many sensor applications across enterprises and industries that help them to improve their performances. 

FREMONT, CA:  The Smart Sensor is critical in the Smart Factory of Industry 4.0, regarded as the fourth industrial revolution.

Today people live in a sensor-driven era. Smart sensors do improve the ability to observe and report on the surroundings. They work in almost every sector to make people's lives easier and better. Adjusting lights to match moods, turning on devices such as water heaters, ensuring security, tracking devices, and several other things are just a few examples.

On a larger scale, sensors provide better visibility into business workflows, recognize employee work patterns, and determine facility environmental conditions. As a result, sensors enable enterprise management to track, control, and enhance operational efficiency.

In addition, with IoT technology pervading more aspects of life than ever before, the use of accurate sensors is increasing at an exponential rate. Smart sensors, which are essential components of IoT systems, are necessary for the internet of things to exist.

Along with IoT technology encompassing more aspects of life than ever before, the use of precise sensors is increasing at an exponential rate. The internet of things cannot sustain without smart sensors, which are crucial parts of the IoT systems.

What is a Smart Sensor?

Sensors collect data from specific environments and convert it into measurable electrical signals. Temperature, mass, speed, pressure, and heat bodies such as humans are examples of these properties. A microprocessor then processes the electrical signals to produce results that correspond to a set of actions. Finally, the system communicates the result with receivers in the intended devices to ensure proper operation.

A system may utilize multiple sensors of varying abilities based on the functional complexities and increased feature demands. More receivers, transmitters, power sources, and many more may be included for better outputs.

Types of Sensors

Sensors are classified into several types based on their capabilities to measure physical properties. Let's take a look at some of the most common types of sensors used by businesses.

Motion Sensors

When people enter or leave a space, motion sensors track their presence. When motion is identified, the sensors send signals that cause procedures to increase or reduce power supply to light fixtures. As a result, it automates the on/off switching of lights and other in-house devices depending on the occupancy or vacancy status of the assigned space.

Thermal Sensors 

Thermal sensors are required for automating room temperature in smart buildings and offices. They maintain a steady internal temperature regardless of the outside temperature. These sensors also save energy by adjusting the temperature to match the weather.

Wind Sensors 

Smart buildings must be able to respond to nature intelligently. Wind sensors automatically shut down dust skirts, storm shutters, or retractable awnings when strong winds are identified.

Smoke Sensors

Smoke sensors guarantee the safety of a home or building by providing instant alerts and triggering alarms in the event of a fire. As a result, they significantly increase the likelihood of escaping from accident scenes.
