Abstract

The temperature and humidity monitoring system was developed using various components viz., Arduino Uno, DHT11 sensor, universal serial bus (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), etc. The field testing of the developed temperature and humidity monitoring system was carried out at various locations of the college campus. It was observed that the system worked between the percent variation of 0–8.00% for temperature and 0–5.97% for humidity. The developed system showed the accuracy of ±2°C for temperature and ±4% for humidity. The total cost incurred for the development of temperature and humidity monitoring system along with all accessories was ₹1625.
