Development of a Scale Prototype of Smart Bed Controlled Using a Mobile Application

Abstract:

The need for a technological system for health care for sick people is evident. This work develops a scale prototype of a smart bed controlled through a mobile application. The electronic design consists of two servomotors that act to position the bed; these actions can be activated through the mobile application. At the same time, the patient can be monitored by a camera and an infrared thermometer that sends the data to the application through the Internet. The local operating code is designed so that the position of the bed changes automatically according to a preset sequence. The electronic system is based on the ESP32 board; this chip integrates WiFi communication that allows the connection of the bed with the cloud-based in Firebase. Temperature tests were carried out with the help of people to ensure that the data taken was correct. In addition, bed positions and reception of camera images were tested on a mannequin. As a result, adequate communication was obtained between the mobile application and all the devices installed in the smart bed. Finally, an acceptance test is applied that validates this proposal with a good score.
