IV Bottle Level Monitoring System

In this paper a method is proposed for Intravenous (IV) fluid level monitoring, using the signal from the Wi-Fi modem. Wi-Fi signal is allowed to incident on the IV fluid container embedded with metamaterial array that act as signal reflector. The reflected Wi-Fi signal is captured by the reader and is analyzed based on a threshold value set for indicating the level of the container. Reader consists of a rectenna and amplifier circuit which convert Wi-Fi signal to DC voltage. This output DC voltage is further processed to monitor the level of the IV container to a remote location using wireless communication protocols.
