These measurements are interpreted by the microcontroller, of which some are received from the sensors using communication protocols specific to each sensor (such as I2C, UART and SPI) or with direct analog measurements such as the emergency button.

  • Another type of alert is caused by sensor interruptions such as the vibration sensor, which when detecting a high vibration level exceeding a certain voltage preset by the user (for example, a strong blow to the head), the sensor activates the interruption external, waking up the electrical system if it was hibernating and giving the mobile device the ability to send an alert to the platform that the user suffered a strong impact.

  • Other actions that can be performed through the platform are to locate users who have a mobile device, alert one or many mobile devices either because they are being sent to call or because the measurements of fixed devices and readings of the same device
  • the user's mobile phone exceeds the risk thresholds (when selecting on the platform that a certain device is being searched, a search command for a certain mobile device is sent to the coordinator via the internet or intranet, the coordinator sends a wireless alert to All fixed devices and the latter send a wireless signal to nearby mobile devices. Only the searched device will accept the alert sent from the platform), and perform geofences to restrict the passage to one or many mobile devices in areas defined by the system administrator.
  • a mobile device detects that its measurements exceed the thresholds, it immediately alerts the user with vibration, lights and / or sound. This measurement is then sent wirelessly to the fixed devices (which also make measurements of the environment). Both measurements (from the fixed device and the mobile device) are sent to the server and the values are compared there. If the fixed device also exceeded the thresholds, the system administrator is alerted. If the fixed device does not match the mobile device, the system administrator is alerted to this inconsistency and it is recommended to check the inconsistencies in person.
