DEVELOPMENT OF DS18B20 TEMPERATURE SENSOR IOT DEVICE USING SECURE API CONNECTION

Abstract

In this paper, a low-cost IoT device using the DS18B20 temperature sensor is proposed. This IoT device has been designed in such a way that it can be used in the development of a predictive maintenance system intended for fire prevention in production halls or other types of buildings. Thus, the sensor must be configurable to be able to acquire temperature values at certain time intervals, and in case of detecting that a certain pre-set value of the acquired temperature is exceeded, to connect via HTTPS protocol to an API endpoint of a software solution allowing an automatic recording of a maintenance task. This maintenance task will allow the maintenance team to be informed and manage the incident with traceability. In the practical experiment validating the functioning of the IoT device, it was connected to an existing task management software solution on the market.
