The objective of this paper is to achieve a functional system in terms of hardware and software, to measure temperature and humidity. In this paper, we use a microcontroller based DHT11 sensor was designed developed to measure the value of temperature and humidity at room temperature. A microcontroller PIC16F877A was used to control the developed system's function. The system was measuring the temperature from 0ºC to 50ºCand the humidity RH from 20 to 90.the reading was displayed in a liquiddoi:10.5281/zenodo.3589885 fatcat:buld45am25fghasfuhnsl2cpwq
