A NOVEL ARCHITECTURE FOR MEASUREMENT OF TEMPERATURE, RELATIVE HUMIDITY, AND DISPLAY OF SCROLLING MESSAGE ON LED DISPLAY BY USING BLUETOOTH INTERFACE WITH ARDUINO NANO

Abstract

The measurements of temperature and relative humidity remotely by using the appropriate sensors are not only important in environmental or weather monitoring but also crucial for many industrial purposes. A device for weather monitoring has been developed as described in this paper to monitor the temperature and humidity using digital components. An LED display is also connected to the Arduino Nano to display the measurements. The goal of this project is to implement the temperature and humidity system that will perform the observation and monitoring of the servers in the rooms, the temperature and humidity system was implemented by using Arduino Nano Printed Circuit Board (PCB). The system gave results with more accuracy when compared with other systems that measure temperature and humidity as DHT-11 Sensor was used.
