Top 20 IoT Projects For Beginners in 2021

1) Remote Health Monitoring System for COVID-19 Patients – IoT in Healthcare

IoT Project_Remote Health Monitoring System for COVID-19 Patients – IoT in Healthcare 

Problem: Our world today is fighting against a global enemy, Coronavirus disease or Covid-19. The virus which causes Covid-19 transmits via droplets produced by an infected person sneezing, coughing, or exhaling.

If you are a healthcare worker or a caregiver, you are at risk of catching the virus as you will be in close contact with the patient. This is where Remote patient monitoring or RPM IoT project idea finds its application. RPM is essentially a way of gathering medical data outside of conventional healthcare facilities. But it is not easy for all to set up an advanced Remote Patient Monitoring system at home. And this IoT project aims to provide an affordable solution for the same.  

Solution: This is a cost-effective and easy-to-build automated RPM system. The device requires the person to stand near the non-contact temperature sensor, then the caregiver or the medical personnel presses the start button, and the device will collect and log the measurements (including date and time) into Google sheets. Further, we can send the data to doctors so that they can monitor them from anywhere.

This IoT Project Can Be Very Helpful For

  • Caregivers or someone who is sharing space with a patient
  • Patients living in remote villages areas who do not have easy access to advance healthcare facilities

2) Get Notified About Covid-19 Vaccine Availability in CoWin – IoT in Healthcare

IoT Project_Get Notified About Covid-19 Vaccine Availability in CoWIN – IoT in Healthcare 

Problem: Many countries are still battling with Covid-19. The number of Novel Coronavirus infections is rising to set new records daily. India has become one of the three most Covid-19 affected countries in the world. India is among the top three Covid-19-affected countries in the world as of May 2021. The Indian government, on the other hand, is struggling to bring vaccines to its population. People are unable to book slots in the Cowin App, due to the limited availability of vaccines and heavy website traffic.

Solution: This is a hardware device that notifies users when a vaccine slot is available. Now note that this project is built upon an API used by the Indian Government on the official website to check the availability of vaccine slots. This is a simple yet interesting IoT project for beginners. The Arduino program written in this project will collect data and notify users when a vaccine slot is available in CoWin.

IoT Project_Push up Counter - IoT in Fitness 

Problem: Anyone who is into fitness or has recently started exercising knows that push-ups are one of the most common workouts. But the problem occurs when you lose track of your “sets” and “reps.” It could be because of many reasons, including the background music you play during the workout. While we have wearable devices to track our walks or runs, there are a few basic workouts like push-ups which are difficult to keep track of.

Solution: This is a fun IoT project that aims to build a prototype of a push-up counter with the help of a KEMET pyroelectric sensor and Arduino. An interesting fact about this IoT device is you can count your squats and many other workouts too. You just have to be creative and find ways to use this to counter in the right place.  

While doing

  1. Push-ups: Keep the sensor on the floor directly under your chin.
  2. Jump ropes: Keep the sensor in front of your legs, the point on the floor right before the rope hits the ground.  
  3. Squats: Well…you got the idea.
