Inspiration

Presently the whole world is battling through the COVID-19 pandemic. In this crisis wearing a mask and social distancing are the only two measures to prevent the spread for this pandemic. Wearing a mask is necessary and compulsory for public health care and controlling the spread. So it is all of our duty to obey all these protocols. Currently in our country police personals and other authorities are been bestowed with the duty to monitor all theses. But this can be tedious and limited only on pathways and roads, but what about places of work, offices, institutions, etc. Many people don't know whether they are effected or not, if social distancing is not maintained properly the disease can spread widely. So to monitor this strictly we need a monitoring system that reduces human efforts. In this corona period hand sanitizer is an essential thing. Because it can kill the COVID19 virus. But use the of normal sanitizer bottle become very danger. When an infected person press the bottle trigger, The virus may spread from this hand sanitizer bottle. We can solve this by using Automatic hand sanitizer bottle. Automatic means, no need to trigger with our hand. Just place your hand near the bottle, the bottle will automatically trigger. And also effected peoples should needed to separate from crowd for this we have to check body temperature so we introduced non contact thermal detector.

What it does

As a solution to this problem we propose a system that monitors whether the person is wearing a mask or not. It can correctly identify and will show the result correctly. Anyway it is our duty to wear a mask in this situation. This system can be easily synchronized with the surveillance camera present in any commercial, industrial, infrastructural or any kind of buildings and can alert when someone enters without mask. Our system is developed to enable and enhance risk and mitigation efforts. The goal is to help the agencies to detect, alert and report on human temperature, social grouping in addition to facial protection. Counting of people in a crowd is detected by IR sensors and measurement of temperature by using infrared sensor. As a solution to the sanitizer problem, we design an automatic hand sanitizer bottle. No need to trigger the bottle , just place the hands near the bottle. It will automatically trigger.

How we built it

With the help of deep learning this system can detect whether a person is wearing a mask or not by classifier technique. A dataset is collected which contains several images of with mask and without mask and made our neural network model (Mobile Net).Then we trained out neural network model. Next predicted the labels for Masked and Non masked images using out the trained Mobile Net. Finally we predicted the labels for Masked and Not masked in live video from webcam using our trained Mobile Net. The camera used here can be a thermal camera; this camera can be used to detect the presence of people, thus by using this we get the count of people in a room. we have set a threshold value of count of people on the python program side, who can enter a institution according to COVID protocol Hence if the protocol is violated the respective authorities will be alerted with a message or through an app. By the use of, if two persons come too close and violates the minimum distances prescribed the system alerts them on this. The system also detect the distance by using deep learning technique work as non contact infrared thermometry temperature measurement to screen for elevated skin temperatures (EST) in any institutions. Skin temperature is not same as body temperature. Alerts are generated to authorities and we can separate the person in any place who has covid19 symptoms. Review can be made through a web application. Automatic hand sanitizer dispenser using Arduino: Here, we use an Ultrasonic distance sensor, Servo motor and Arduino board. here we are using Arduino Uno. When we place our hand in front of the distance sensor, it will help to the Arduino to measure the distance from the sensor to object (here the hand). if the object in the desired range, Arduino will write the servo to 180. Servo motor is mounded on the hand sanitizer bottle. And the trigger of bottle is connected to servo by a thread. When servo motor rotate, the trigger will press.

Challenges we ran into

we had read many papers based on this. For better knowledge ,we had explored many journals. At last we found out.

Accomplishments that we're proud of

*Our idea is selected by CUSAT - CATDM selected for funding. *Selected by NIC - First phase

What we learned

we learned how to prepare a face mask detection system, automatic hand sanitizer system, non contact temperature measurement system, social distancing detection system using all those technologies.

What's next for CoV-2 SHIELD

we really want to make it happen.
