It’s a dangerous gap in medical care—if an IV bag runs completely dry, it can lead to blood backflow or severe air embolisms. I wanted to engineer a way to completely automate this process. Under my development studio, Synapse Lab, I built LifeFlow: a precision IoT medical monitor that uses an ESP32, an HX711 amplifier, and a load cell to continuously track IV fluid volume by weight. In this breakdown, I'm going to walk you through the exact hardware architecture, the C++ threshold logic, and how I routed the data to a real-time Blynk dashboard to keep medical staff instantly alerted.you can check it out at synapselab.in/project.html</p> showdev esp32 iot healthtech
