Connect one verified path at a time.
Explore the named components and standardized signal flow, then use Source Check to verify exact physical pins, values, and topology before applying power.
Trace this circuit.
Covid-19 Patient Monitoring Device based on LoRa using The Things UNO: interactive parts, standardized terminals, responsive anchored wires, student explanations, and the original circuit reference in one shared system.
Trace before wiring
Follow power, ground, inputs, processing, and outputs in that order. Never guess a pin from package shape alone.
Connect with power off
Make short, labelled connections and share a common ground only where the schematic requires it.
Inspect every joint
Check continuity, polarity, adjacent shorts, and loose connections before the first power-up.
Open all source diagrams and build views 3 visuals
Confirm the hardware-only control path.
This project does not include firmware in the source. The circuit itself provides the required behaviour.
How to connect
- Match every controller label to the circuit view and source pin map.
- Join grounds before signal wires when separate low-voltage supplies are used.
- Keep motors, relays, pumps, and other loads on a suitable driver and external supply.
Common mistakes
Reversed VCC/GND, board-label versus GPIO-number confusion, missing common ground, and charge-only USB cables.
Troubleshoot
Disconnect loads, continuity-test one path at a time, then test with a current limit.
Software preparation
No IDE, board package, library, or firmware upload is required for this project.
If you add a programmable controller as an extension, document its pin map separately.
How to upload code
The original design is implemented entirely in hardware, so proceed after verifying the circuit and supply.
Assemble, deploy, test, and troubleshoot.
Use the complete source notes in build order, then pass the final checks before calling the project finished.
Build in functional stages
- Power and regulation
- Controller or processing stage
- Inputs and sensors
- Outputs and loads
- Enclosure and strain relief
Power up safely
- Inspect unpowered continuity first
- Apply the lowest safe current limit
- Measure supply rails before signals
- Add one load at a time
- Record expected and actual results
Work from simple to complex
- Confirm power, ground, polarity, and orientation
- Compare each pin with the source
- Test inputs separately from outputs
- Replace only one variable at a time
- Power off before every correction
Follow the documented instructions.
These notes come from this project's source and remain in their original order.
Project overview
Project build noteThings UNO
Figure: Lora network based covid-19 patient monitoring device.
Project build noteUsing sensors and connected networks, we have developed a patient monitoring system that can autonomously monitor patients’ health
conditions. The Covid-19 system was specially manufactured for patients with this condition. The biological behavior of a patient can be gathered by several sensors. Information about biological processes then goes into the IoT cloud. By processing sensor data, the system is more intelligent, and can tell when a patient is in critical condition. Nurses and doctors receive instant alerts and hospital personnel receive push notifications. Nurses and doctors’ benefit from this system because they can observe the patients remotely without having to visit them personally. Relatives of patients can also gain access to the system with limited access.
This monitoring system is controlled using the Things UNO, a Lora development board. This board collects information from various health sensors (described in the Hardware Components section) that provide information about patient health parameters. Data transmission from the Things UNO to the Lora Gateway (The Things Gateway) is also handled by the Things UNO. The Lora gateway provides a connection to the Amazon Web Services IoT cloud platform. This cloud is used for managing this system. The data has been visualized using a Mobile application. For displaying real- time sensors data, such as the present health condition of a patient, various charts and gauges have been employed. Doctors and nurses can use this application remotely to monitor patients without visiting an ICU unit. A push notification is sent to appropriate doctors or nurses regarding the emergency situation of the patient due to the nature of intelligence, by processing the sensor data, Equation-I identifies the patient's emergency condition. During a 24-hour period, the hospital in charge personnel (ICU in charge person) continuously monitored multiple patients online via our cloud-based desktop application (shown in Figure), which makes the ICU process more efficient, Throughout the application's lifetime, all of the applications tapped into the Internet of Things and visualized the data in real-time, using visualizations such as gauges, Sparklines, and Text.
