As we continue our series on innovative Internet-of-Things (IoT) applications, we shift our focus toward specialized systems that enhance medical care, industrial safety, and urban resource management. These projects utilize robust microcontrollers and the IOTGecko platform to provide real-time data and remote control capabilities.
Advanced Healthcare and Patient Care
21. IOT Based ICU Patient Monitoring System The Intensive Care Unit requires constant vigilance over a patient’s vital signs, a task that is often tedious to perform manually for multiple patients. This Raspberry Pi-based system automates the process by collecting blood pressure (systolic and diastolic), heart rate, and body temperature via sensors. The data is transmitted over Wi-Fi to a web interface, allowing doctors to monitor critical parameters from any location worldwide without manual intervention.
22. IOT IV Bag Monitoring and Alert System During healthcare crises like the COVID-19 pandemic, monitoring every intravenous (IV) drip personally is challenging for frontline workers. This system uses a weight sensor and an Atmega microcontroller to detect when fluid levels in an IV infusion bottle run low. The current level is displayed on an LCD and transmitted to an online dashboard, triggering an automated alert as soon as the bag becomes empty.
23. IOT Alcohol & Health Monitoring System In high-stakes environments like military bases, hospitals, and factories, ensuring staff follow work ethics—such as not working under the influence of alcohol—is critical. This circuit uses an MQ 3 sensor for ethanol detection and a blood pressure sensor to monitor the user's health status. Results are reported remotely over the internet, helping to prevent workplace accidents.
Industrial Safety and Maintenance Robotics
24. IOT Gas Pipe Leakage Detector Insect Robot Monitoring extensive gas pipeline networks for leaks is traditionally costly. This project proposes a fully automated insect-like robot that clings to the outer surface of metal pipes and moves along them to detect combustible gases using specialized sensors. Upon detecting a leak, the robot uses an integrated GPS module and GSM/Wi-Fi modem to transmit the exact location of the fault to an IoT login system.
25. IOT Underground Cable Fault Detector Project Locating faults in underground cables often requires digging up entire lines, which is labor-intensive and expensive. This system utilizes a potential divider network to sense voltage changes when a short circuit occurs. An Atmega microcontroller calculates the exact distance to the fault and updates the information to an online portal via IOTGecko, allowing repair teams to dig only at the precise fault location.
Sustainability and Smart Resource Management
26. IOT Garbage Monitoring System To maintain urban cleanliness, this system uses ultrasonic sensors placed over garbage bins to track the level of waste collected. An AVR family microcontroller compares the detected level with the bin's total depth and transmits a graphical status update to a web page. If the garbage level crosses a set limit, a buzzer sounds, and the online dashboard highlights the bin for immediate collection.
27. IOT Liquid Level Monitoring System Designed to prevent the overflow and wastage of liquids, this project monitors multiple containers simultaneously using HC-SR04 ultrasonic sensors. Driven by an Atmega microcontroller, the system provides a color-coded graphical view of liquid levels on a web page. When levels exceed specified limits, it alerts the user via an online notification and an onboard buzzer.
28. IOT Irrigation Monitoring & Controller System Managing large-scale farmland is simplified through this Arduino-based system, which allows farmers to monitor soil moisture from remote locations. By checking data on a website, a user can toggle the "Motor status" to remotely turn a water pump on or off, ensuring crops receive optimal hydration without the risk of waterlogging or drought.
Security and Automated Access Control
29. Biometric Attendance System Over IOT This system provides a remote monitoring solution for schools and offices by allowing attendance tracking from anywhere in the world. It uses a fingerprint sensor interfaced with an Atmega microcontroller to authenticate registered users. Once a user scans their finger, the system verifies their identity and transfers the data to the IOTGecko platform for real-time reporting.
30. IOT Electronic Door Opener For advanced security and convenience, this project enables remote control of electronic door locks over the internet. Authorized users log into a web interface to send load switching commands, which are received by a Wi-Fi-connected Atmega microcontroller. The controller then instructs motor drivers to rotate and fully open or close the door based on the user's input, regardless of their physical distance from the entry.
