    Design and Implementation of a Wireless Patient Health Monitoring System
    (IEEE, 2019) O. Manzombi, O.; Dogo, E. M.; Nwulu, N. I.
    This paper presents the design and implementation of an IoT wireless patient's health monitoring system. The system can be used to continuously monitor the body temperature and pulse rate of a patient located in a hospital room using biomedical sensors. The temperature and pulse rate values are taken from the sensors and processed by an Arduino Uno. Furthermore, they are sent wirelessly via RF communication using a 433 MHz transmitter and receiver kit. The readings are encoded and sent to the receiver where they are decoded and displayed on an LCD screen. Finally, the temperature and pulse rate values are also displayed and stored online using an Arduino Ethernet Shield 2 for future analysis.

    Glare Stopper: The Automatic Car Headlight Management System
    (2023-03-22) Abdullahi Daniyan, Samuel S. Ilupeju
    The growing number of vehicles on roads calls for increased safety considerations, especially during night driving. A common issue is the misusage of high beam headlights, which can cause light glare for opposing drivers due to the high intensity beam a driver receives from oncoming vehicles. This is called the Troxler Effect. This is a safety critical issue given that the human eyes are very sensitive to light, and when eyes suddenly encounter high intensity light, one’s vision get temporarily affected and require some time to recover the vision. During this vision recovery window, the vehicle has covered some distance which could increase the likelihood of an accident occurring. To address this, we propose an automatic car headlight management system that adjusts a vehicle’s headlights based on light intensity of oncoming vehicles. The system utilizes an Arduino Uno microcontroller and an LDR sensor installed on the driver's side to detect light levels of at least 700 lumens. The microcontroller then sends a command to a relay, which switches the headlights from high beam to low beam. Results demonstrate effective performance of the proposed system in terms of achieving faster switching time and consuming lower power.
