Hemtjänstlogistik: Övervakningssystem med kommunikationsenhet för Aäldrevården (Swedish)
Abstract [en]

Humans are growing older which presents challenges for the health care system. One solution for allowing individuals to continue living in their home, despite age related dif- ficulties, is a sensor based surveillance system. These systems can monitor a number of parameters, for example motion or temperature. If certain limits are exceeded the sys- tem can notify family members or health care services. The aim of this project was to build a prototype of such a system which also had to be cheap and easy to install and maintain. The final prototype consists of a motion detection sensor in the bathroom, a temperature sensor around the kitchen stove and a temperature sensor for measurement of ambient room temperature. Each sensor is connected to its own Arduino and they are all programmed with different limits. The sensors communicate wirelessly with a central hub through the communication protocol LoRa. Once the central hub, which consists of a Raspberry Pi, receives a LoRa signal it sends an email to a chosen address.

Abstract [sv]

Människor blir allt äldre vilket är en utmaning för sjukvården. En lösning som tillåter individer att fortsätta bo i sina hem, trots åldersrelaterade svårigheter, är ett sensorba- serat övervakningssystem. Sådana system kan övervaka ett flertal parametrar, exemåelvis rörelse eller temperatur. Om vissa gränser överskrids kan systemet underrätta anhöriga eller hemtjänsten. Syftet med det här projektet var att bygga en prototyp av ett sådant system, som även skulle vara billig och enkel att installera och underhålla. Den slutgiltiga prototypen består av en rörelsedetektor i badrummet, en temperatursensor vid köksspisen och en sensor som mäter den omgivande temperaturen i ett rum. Varje sensor är kopp- lad till en egen Arduino och de är alla programmerade med olika gränsvärden. Sensorerna kommunicerar trådlöst med en centralenhet genom kommunikationsprotokollet LoRa. När centralenheten, som består av en Raspberry Pi, tar upp en LoRa-signal skickar den ett email till en vald adress.
