Low-Cost Wearable Device to Provide an Effective Solution for Contact Tracing and Logistics

The paper introduces a low-cost wearable band that does the tedious, repetitive task of entering your required details in any shop or organization, as well as keeping a record of all the people you have come in contact with. There are two aspects of our device:1)If a person enters a shop with our device, the band will transmit the required information of the wearer to the reader kept at the shopkeeper's side wirelessly. The transmitted information will include the wearer's information (as per government guidelines) masked in the band's Unique ID along with their temperature status (whether having a temperature above 100°F or not).2)When two persons come near each other over a distance of 6 feet, the unique ID broadcasted from each other's bands gets stored in the other's band. If any of them tests positive for Coronavirus Disease (COVID-19) or similar diseases, his/her unique ID can be used to trace primary contacts and take appropriate steps to contain further spread.Privacy is key! So, we are reengineering the primary concept of contact tracing and logistics while keeping the user's information safe and secure. © 2023 IEEE.

Arduino Based Smart Dustbin for Waste Management during Covid-19

India has perceived an enormous upsurge in garbage during 21st century due to adopting urbanization rapidly. In addition, as the population increasing drastically, which inherently produce huge amount of garbage. The overflow of the garbage and lack of maintenance are the main reasons for many diseases and also for spoiling earth environment. However, the entire world has faced the problems due to spreading of Covid-19 through the air due to the hazard waste is being generated in specific Covid hospitals, quarantine zones are directly dumped into the dustbins. The frontline warriors (doctor, nurse, police) working in these unorganized dustbin environments are getting infected with Covid-19 and are became a primary contact for spreading of virus. Thus, it is very much essential to implement a systematized and well-designed mechanism to overcome this problem. In this work, a hardware prototype for smart dustbin based on Arduino has been proposed that can be installed in hospitals, medical centres, municipalities, households for the sake of environment as well as front-line workers. The proposed model of smart dustbin has PIR sensor and ultrasonic sensor for human motion detection and sense the level of garbage present in the bin respectively. An alert system based on GSM has been interfaced with Arduino which sends the alert messages based on level of the garbage at regular intervals. The proposed model work with very low power and increase the security for front-line workers from the Covid-19. © 2021 IEEE.
