11 best internet of things (iot) applications in 2023

1. IOT Based Smart Agriculture Solution

Agriculture is one of the biggest sectors of India, and the growing population has put added pressure on agriculture. So, integrating IoT with agriculture will help farmers cultivate better and on a larger scale. 

IoT sensors provide details of soil chemistry and fertilizer profiles. For example, CO2 levels, moisture, temperature, acidity, and nutrients. Thus, farmers can find how good the soil is for a particular harvest. 

Smart irrigation is another IoT-based application that helps farmers to use water efficiently for farming. The IoT application checks the dryness and moisture levels of soil and initiates water flow accordingly. If the soil reaches a certain moisture level, it stops the water flow and starts the water flow if the soil dryness reaches below a certain level. Thus, it helps in the optimal utilization of water for irrigation. 

Livestock Tracking

IoT applications are extremely useful in solving the issues faced by the livestock industry. For example, animals eat unhealthy things like plastic and fall sick, have no track of livestock, or lost animals. The IoT chips enable farmers to keep a close eye on livestock. They can keep track of their location, vaccination details, and other vitals. 


IoT-enabled livestock monitoring helps check and keep track of all the animals remotely and also provides information on every animal on the farm. 

The key benefits of monitoring livestock using IoT are

  • Monitor the health of livestock in real-time and treat animals and prevent the spread of disease.
  • Track grazing animals and monitor grazing patterns and avoid unhealthy eating. 
  • Gather and analyze data for cattle health & optimize breeding practices.

2. IoT Applications in Healthcare

The pandemic opened our eyes to realize a greater need for technological advancement in healthcare. The IoT-based applications filled that technological gap and enabled consumers and patients to connect remotely. The IoT application involves attaching sensors to a patient’s room. It allows doctors to monitor them remotely by sending continuous data and also alerts the doctor of abnormal parameters. Thus, doctors can monitor at-risk patients like the elderly and patients with chronic diseases.

  • IoT applications help streamline patient medical records by making real-time data available across departments. In addition, the data collected in real-time also helps in medical research.
  • IoT apps optimize the manufacturing process and also help in intelligent inventory management. It, thus, helps in lowering drug costs. 

3. IoT in Wearables

The Internet of Things is highly utilized in wearable technology like smartwatches, fitness trackers, smart eyewear, and linked fabric. Wearables have multiple functionalities including tracking locations, showing reminders, tracking physical activity, and more. 

Here are the use cases of IoT in wearables

  • Wearables help fitness lovers to track their activity during workouts like running or cycling. Smartwatches and fitness bands are great examples. 
  • Wearables help track locations; for example, parents can keep track of their children, or caretakers keep track of the elderly.
