Low-Cost Syringe Pump with Remote Monitoring, Alarm Functionality, and Health Tracking

This project presents a low-cost syringe pump with remote monitoring and alarm functionality, along with basic health monitoring, designed for use in rural hospitals and home-based care. The system uses an affordable ATmega328P microcontroller and a stepper motor with a lead screw mechanism, driven by a stepper driver, to ensure accurate and controlled linear motion for medication delivery. A Real-Time Clock (RTC) module is integrated to enable time-based medication scheduling, enhancing reliability and ensuring timely alerts. The system also features temperature and pulse oximeter sensors for monitoring basic health parameters. Remote monitoring is supported by the Global System for Mobile Communications (GSM) connectivity allowing alert messages to be transmitted via a GSM module. The local notifications given through an active buzzer and a Light Emitting Diode (LED) indicator. The programming was done using Arduino IDE, and Printed Circuit Board (PCB) designs were completed using EasyEDA software. Battery backup ensures operation during power cuts. Key findings include a resistor–diode network to reduce keypad pin usage, a connected pull-down pin method for sharing the GSM module across two PCBs and using effective lead screw method to get a linear motion from the rotational movement. Experimental testing confirmed an accuracy of over 98% in volume delivery and flow rate.
