Hello everyone, I´m currently working on a student project for my university.
Since I´m unfamiliar with Arduino boards and shields I have no idea how to meet my requirements. I was researching for two days but it did not help me much so far.
The Project:
We´re developing a smart walking stick for elderly people. The cane should send it´s
-location (indoor and outdoor via GPS, Wifi, and ultrasonic)
- puls data
to a server. We also have an app (IOS/ Android) which is reciving the data from the server.
Acceptance criteria:
- Location should be traceable and precise (<10 m)
- We need to integrate GPS in the stick
- We need an alternative location service if GPS is not working (eg wifi)
- Indoor navigation would be a nice to have (ultrasonic, ibeacon, infrared…)
- Puls tracker needs to be integrated in the stick and sending data to the server in/ close real time
- The Board and shields should run on battery (should last at least 4 hours) and should be recharged via usb/ micro usb
- Not required but nice to have: sending push messages via sim card directly to the smartphone in case of an emergency (puls rate goes down…)
Questions:
Is this even doable?
Do I need a GSM Shield/ Sim Card in order to send location and puls data to the server? Or how does this work?
Which board / shields / chips are most suitable for this and can I connect all of them together?
Is there an option to shut down wifi most of the time to save energy (By using a fused location provider as software for example)?
Which capacity should my battery provide?
Does anyone of you have an idea of which puls tracker chip I could use? The tracker should be inside the stick. There will be direct contact with the fingers and hand of the person using the stick.
So far I found these hardware chips which seem to be necessary:
Boards:
- Arduino UNO Wifi: Arduino - Home
- ArduinoMKR1000: https://www.arduino.cc/en/Main/ArduinoMKR1000
GPS:
- Geolocation Tracker (GPRS + GPS) with SIM908: https://www.cooking-hacks.com/documentation/tutorials/geolocation-tracker-gprs-gps-geoposition-sim908-arduino-raspberry-pi/
- skm53-gps: tutorial.cytron.com.my/2012/08/16/skm53-gps-module-starter-kit-skgps-53/
Indoor navigation:
- DEBO SEN ULTRA: DEBO SEN ULTRA: Entwicklerboards - Ultraschall Abstandssensor, HC-SR04 bei reichelt elektronik
Internet/ Sim:
- GSM Shield: https://www.arduino.cc/en/Main/ArduinoGSMShield
I am happy for every advice!
Thank you very much in advance.
