Dementia Security System

I created a dementia security system for my mum...

The system included:

1. Alert Pull Chords
2. Fall Sensor
3. Potential for Bed Pressure pad sensor
4. Potential for PIR Motion sensors

The System had the following ways of alerting you to change in situation:

1. Tablet mounted on a wall (buttons change colour to show status of various alarm triggers)
2. SMS (text messages) relating where the issue has occurred.(Using node-red-contrib-nexmo)
3. Phone Calls relating where the issue has occurred.(Using node-red-contrib-nexmo)
4. Audible alarms possible.....

First Download The Raspberry PI OS From:

https://www.raspberrypi.org/

Selecting Software>Raspberry PI OS

Download the "Raspberry Pi OS Lite"

Unzip the file so that you get the image.... We will be writing this to a MicroSD card soon.

Insert the 64GB MicroSD card into a card reader attached to your PC.

Follow the video bellow:

See Video Below:

The following Commands need to be executed from the Raspberry PI

to login use:

login: pi

password: raspberry

then execute:

sudo apt-get update

followed by:

sudo apt-get upgrade

Typing y for yes if required.....

reboot the PI with:

sudo reboot

then login again and run:

sudo raspi-config

select

System Options > Password

and change the password for the user pi

System Options > Hostname

and give the Raspberry PI a unique hostname

Interfacing Options > SSH

to turn on remote SSH access

Then exit

and reboot the PI again:

sudo reboot

Log back in and then execute:

ip a

The output of which should give you the IP address of the network interface eth0

in my case this is 192.168.36.188

note this as we will be using it later

From the Previous Step we checked the IP address of the Raspberry PI on the LAN:

192.168.36.188

We also enabled SSH and changed the default password for the pi account which we are going to use now with PuTTY to access the PI from our PC....

PuTTY can be downloaded from:

https://www.putty.org/

Opening the program and filling in the IP address and then follow the video for installing Node-Red:
