Idea + Parts
IDEA | WHAT IS THE PROBLEM?
Family members have experienced robberies in stores or restaurants. During a robbery, everything happens so fast, there is no time to look for the cell phone to call the police. Standard security systems are expensive and not yet smart enough to respond automatically while the robbery happens.
For this reason, I have been thinking about an emergency button that is hidden or placed in several places in a restaurant or store. When the alarm button is triggered, it sends an emergency message to the nearest police station. The message contains basic information about the location.
WHO NEEDS AN HELP! BUTTON?
I am thinking of an emergency button as part of a prevention system for restaurants, stores, theaters, offices, etc. Once the police receive the emergency notification, they can react faster and more efficiently. But also for personal use. Family members or friends can be notified.
WHAT DOES ALREADY EXIST?
After searching for some references in the Fab Academy site, I did not find a personal alarm device. I find a project that does something similar, but for tracking patients.
Alarm system track patient condition: ATtiny44, Wifi, App
I also found other tutorials about safety devices or emergency systems:
Emergency button for 7$, Arduino, WIFI and ESP8266
The rescue notification system mainly consists of these parts:
(1) The transmitter: with the help button. It triggers the alarm
(2) The receiver: the hub with WiFi connectivity. It accesses the internet.
(3) The interface application or code: it sends the emergency notification.
-> Update: An interface is not required. The mail is sent directly from the base station (ESP32).
