Challenge
Description
The main solution is firstly transmit the data from sensor to the phone app using the Arduino technology. The main reason to include the phone for signal transmission is that there might be the case where the button can be pushed accidentally, and app in the phone will have an option to dismiss alarm signal. In case the user will not be able to confirm the signal, the app will wait for 30 secs and if there will not be any response it will send it to official authorities.
