The number of cardiac patients and aged individuals are at a rise all around the world. Taking care of such individuals is a major challenge these days. In many cases, these patients require special care and regular monitoring of vital signs like blood pressure (BP). Focusing a prevalent idea of wireless brain-computer interface (WBCI), an innovative research work is considered to meet essential routine monitoring of BP for cardiac patients and aged people without any reliance. The research framework involves the use of wireless electroencephalogram (EEG) headset to control wrist BP and arm BP monitors to determine accurate BP readings in the proposed system. An Android application "Smart Home Monitor" is developed that screens the information from the headset. The research framework is tested on ten individuals to examine the precision in BP readings from two different BP monitors. Results specify that both upper arm blood pressure readings i.e. Systolic BP readings (SBP = 119.6 ±5.1 mmHg) and Diastolic BP (DBP = 79.5 ±7.4 mmHg) were found to be better than the wrist BP readings (SBP = 128.2 ±11.7 mmHg and DBP = 83.6 ±10.3 mmHg). This examination assessed that the designed system empowers the framework to be reliable, remote and compact.

In today's era when precise, accurate and timeefficient systems are in great demand, automated techniquessupersede manual practices. As a need of time, we introduce awireless, automated, cost effective, yet reliable and efficientsystem of fluid dispensing. Our prototype system can dispensevarying amounts of fluids in milliliters (maximum 1L) as perdemand of the user. It uses the principle of time based fluiddispensing achieved through the built-in timer property of theAT89C51 microcontroller. To satisfy the principle used andverify the system's accuracy, fluids of varying viscosities weredispensed and monitored. The experimental results of thewireless fluid dispensing system when tested showed linearrelationship between the dispensing time and desired volumes offluids having differing viscosities. The added feature of wirelesscontrol using HM-TRP series transceiver module along with onsitecontrol via a keypad eliminated the need of physical presenceof operator within the range of 10 meters in order to make thesystem operational. This system can be used in pharmaceuticaland beverage industries as well as in different laboratories fordispensing and filling volumes of fluids with varying viscosities.
