In the healthcare sector, IoT sensors play a vital role in monitoring the patients’ medications, vital signs, and other health conditions that can be stored and analyzed in the electronic health record (EHR) systems of hospitals and clinics. It also enables healthcare professionals to track their patient’s health remotely and diagnose them as early as possible. 

Examples of these kinds of sensors can be implanted inside the human body (e.g., glucose monitoring sensors)  or integrated variously through medical devices (e.g., vital sign monitoring sensors) and wearable devices (e.g., activity and movement sensors commonly used in smartwatches). Either way, through these healthcare IoT sensors, healthcare professionals can immediately monitor and optimize treatments for patient safety.

IoT Sensors for Real Estate and Facilities Management

In real estate technology, sensors can collect data from various assets and equipment and offer real-time analysis, transforming the management industry. Using these sensors, we can monitor and improve the building's efficiency, reduce energy consumption, and increase the occupant’s comfort and well-being. 

Integrated into devices and systems, these types of sensors detect energy usage and automatically analyze the gathered data to help reduce environmental footprint and energy costs (e.g., IoT Based Energy Monitoring System), as well as determine whether a room or space is occupied (e.g., Occupancy Sensors), and enhance home security (e.g., Security Sensors - motion sensors, temperature sensors, windows sensors, etc.).

IoT Sensors for Smart Farming

The Internet of Things for agriculture provides farmers with an efficient way to farm by detecting farming environments such as soil moisture, temperature, weather patterns, pest activity, and indications of crop health. With these types of sensors, monitoring crops can now be more accessible and allows the farmers to determine when to harvest or when the crops need more water and nutrients from fertilizers.

With the data collected by various sensors, the Internet of Things (IoT)-based Smart Plant Monitoring System tracks the growth of the plants, enabling farmers to optimize farm management for higher productivity and sustainability.
