How does it work:

Starting 6am, the device will started to monitor the sound in the room. Once alarm sound detected, it starts the timing and activates the PIR motion sensor placed near the ground. If no motion of leaving the bed detected in 5mins, it will activate its own alarm sound. In another 5mins, the devices sends a message to the roommate for help. If motion detected anytime, the alarm will be stopped. The system will only be triggered once in the day to prevent false alarm triggered by the noise in the day time. System resets at 6am.
