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 liquid Crystal Display. MikroC language program was developed to control the microcontroller.
