Smart Sensors: Applications, Benefits, and Working

It’s a sensor-driven era. Smart sensors do enhance the capacity to observe and report on the world around us. They perform in almost all sectors to make human life easy and much better. Adjusting lights to the tune of moods, turning on devices including water heaters, ensuring security, tracking devices, and many more are just a few to name so. On a bigger scale, sensors enable greater visibility into business processes and workflows, identify employee work patterns, and determine environmental conditions of facilities. Thus, sensors also allow enterprise management to monitor, control, and improve operational efficiency.

Alongside, with IoT technology penetrating every aspect of life than ever before, the use of accurate sensors is exponentially growing. The internet of things cannot exist without smart sensors and constitute the vital components of IoT systems.

How do Smart Sensors Work?

Sensors capture data from preferred environments and transform their physical properties into measurable electrical signals. These properties include temperature, mass, speed, pressure, or presence of heat bodies like humans. The electrical signals are then processed by a microprocessor to give outputs that correspond to a set of actions. The system finally communicates the output with receivers in the intended devices for favorable functioning.

Depending on the functional complexities and increased feature demands, a system may employ multiple sensors of different capabilities. For favorable outputs, it might include more receivers, transmitters, power sources, etc.

Types of Sensors

Sensors are of different types based on their capability to measure physical properties. Let’s look into some of the common types of sensors in use among various enterprises.

Motion Sensors

Motion sensors are designed to detect people-presence when they enter or leave a space. When a motion is detected, the sensors send signals to trigger processes that increase or decrease power supply to light fixtures. Thereby, it automates the switching ON/OFF of lights and other in-house devices based on the occupancy/vacancy status of the assigned space. They can immensely save energy in commercial applications that deal with larger areas and people. These sensor-driven systems are also widely used in hospitals to monitor hand-hygiene compliance.

Light Sensors

Tuning light to the time of day, month, or year is the prime functionality of light sensors. It automates luminaire functioning in smart buildings besides enabling human-centric lighting, daylight harvesting, and light scheduling for energy savings, efficiency, and ambiance.

Thermal sensors 

Automating room temperature in smart buildings and offices require thermal sensors. They maintain a constant internal temperature, no matter how the external temperature varies. These sensors also save energy by balancing the temperature in tune with the climate.

Wind Sensors 

Smart buildings need to respond to nature smartly. Wind sensors automate the shutting down of dust skirts, storm shutters, or close retractable awnings if strong winds are detected.

Smoke Sensors

Smoke sensors ensure home or building safety, as they give instant alerts and trigger alarms in case of fire bursts. Thus, they drastically increase the chance to escape from accident scenes.

Apart from the sensors mentioned, there are lots of other sensors in use in the industry, like time sensors, location sensors, sound sensors, matter sensors, and many more.

What industries do benefit from smart sensors?


Sensors are vital in making healthcare management seamless. The various benefits include,

  • Monitoring hand hygiene compliance

  • Improved space utilization

Check how a California based leading environmental and industrial machinery manufacturer replaced their primitive in-house system to a smart facility.


Sensors designed for smart hotels enable cost savings, bring in revenue opportunities, and drastically improve guest experiences. For instance, thermostats and occupancy sensors allow smart energy-management that wisely utilizes energy, besides automating temperature controls and light settings. Let’s see some of the other benefits of sensors in the hospitality industry.

  • Automated guest interactions
  • Personalized experience delivery with guest data
  • Self-check-in/check-out and automated room entry
  • Push-notifications for room service


Sensor-based technology is changing the way employees interact and work in today’s offices. Smart-sensors are behind this transformation, ensuring improved productivity and performance. The list goes on!

  • Smart lighting for human-centricity
  • Smart HVAC systems for automated climate control
  • Intelligent conference room and occupancy data
  • Indoor wayfinding and smart-navigation

Home Automation

Today, there’s some sensor for every home function, or there will be one soon. Sensors are the backbone of home automation that directs smart devices on when to work and how to work.

  • Automated device activation  
  • Mood lighting and temperature controls
  • Pre-set routine schedules 
  • Theft and unauthorized access detection

There are more sensor-applications across enterprises and industries than what’s explained in the blog. As we all can see, there’s a dazzling list of sensors for all-case scenarios. Today, the world has come so far that without sensor data, many vital functions wouldn’t life-up.
