IoT based live monitoring of elderly people health parameters like temperature, pressure, fall detection and emergency notification button to intimate the emergency situation to the care taker so that the care taker can give instructions from a IoT app to an Alexa device connected with a camera and monitor in the wheelchair system and it also helps elderly people is sitting and getting up from a chair using hydraulics. This smart system can support the elderly and disabled people with high accuracy and efficiency. The proposed Smart Wheelchair consists of various sensors to monitor the body parameters from the wheelchair connected to the central Raspberry Pi 4. In addition to this an emergency notification system is included to intimate the caretaker so that the care taker can give instructions from their Android mobile to an Alexa device, which in turn connected to a display with camera in the wheelchair system.
