Message Queuing Telemetry Transport Based Data Logger

The phenomenon of logging data occurs daily. When a person sees something or experiences an occurrence, their memory of it is stored in their brains for future use. Similar to that, data logging is the process of gathering, examining, and storing data for eventual use. Applications in science, medicine, and industry, knowledge is required for the course of temperature and relative humidity at a specific moment. For recovery of this data from different sources or sensors, data loggers may be employed. A data logger is an electronic instrument that senses temperature and relative humidity by combining analogue and digital measurements with programming techniques. The data loggers take input from the DHT11 sensor. The database receives this info after that. for storing and analyzing the monitored data. A temperature and humidity data logger's design and simulation are presented in this paper.
