An intravenous drip real-time monitoring system is disclosed herein. The system includes a weight sensor, a processor and a cloud server. The weight sensor is configured to detect weight values. The processor is electrically connected to the weight sensor, is configured to calculate the weight values and when the weight values is not larger than a drip threshold, sending an alert information. The cloud server is communication connected to the processor, is configured to receive the weight values via the processor, and compare the weight values and drip setting information to calculate drip remaining time.
