This Do It Yourself patient monitoring system project is provided with complete source code, PCB design, and computer software, It measures Heart Rate and Temperature.
This patient monitor offer a range of options for flexible care, including a portable bedside monitor, compact patient monitor, and vital signs monitor. All patient monitors are designed to give caregivers a clear view of patient information on computer and also sends data to given mobile phone.
Features:
1. Real Time monitoring on computer VB6 Software
2. Remote Monitoring Mode allows to get SMS of patient data.
3. Set points for over Temperature and Heart Rate
4. Displays data on LCD and Computer.
5. Flexible
6. Low Cost

Hi. Can you provide a proteus simulation file for this project? Thanks in advance :)
ReplyDeleteCircuit Diagram (switch only ) and code are different .
can you provide a fresh copy.
