Most of the time, in hospitals, to improve the body's hydration, Intravenous
Therapy (IV) is given. During the therapy, the bottle's liquid level needs to be monitored
continuously. The bottle needs to be changed immediately, once it got empty, to prevent the
blood's reverse flow through the intravenous tube. Any lack of monitoring or continuous
assessment of the liquid level and the delay in refilling the bottle may cause adverse effects.
To minimize the risk factor of the treatment and reduce the workload of the nurse/hospital
staff, an IoT – Based Liquid Level Monitoring System has been developed. This system
measures the liquid level continuously using a load cell sensor. Whenever the fluid level
drops down below a threshold point, an instant alert is made to the concerned nurse/staff
using Arduino. Thus this system becomes useful for nurses and patients during day time as
well as night-time.
