Abstract: Arduino Uno, DHT11 sensor, USB type B cable, adaptor, DC power jack, 9-V battery connector, 9-V DC battery, resistor, liquid-crystal display (LCD) screen, trimmer potentiometer, light-emitting diode (LED) bulbs, jumper wires, micro secure digital (SD) card module, printed circuit board (PCB), and other components were used to create the temperature and humidity monitoring system. The developed temperature and humidity monitoring system was field tested at various locations on the college campus. The developed system had a temperature accuracy of 2°C and a humidity accuracy of 4%. The total cost of developing a temperature and humidity monitoring system, including all accessories, was $1625.
