Abstract
This project is about the development of temperature and humidity control using 8 bit microcontroller and SHT75 sensor. This microcontroller is a low power microchip with AVR RISC architecture by ATMEL company product and it can accepts either assembly language or C language for instruction. AVR Studio 4 software is used for writing and compilation code C language or assembly language before it is send to microcontroller by AVRISP mkII programmer. Design implementation also important. Design implementation including flowchart, OrCAD software and design information for this project. The SHT75 sensor by Sensirion Company is used to sense both temperature and humidity. This sensor is a digital sensor with Analog-to-Digital converter feature. The output from sensor is two bytes in binary number. With microcontroller help, final reading of measurement is converted to float number (two decimal places). System is designed and tested for understanding the effect of silica gel for humidity and temperature inside the chamber. Result shows that system design is stable and reliable. Silica gel can be used for humidity control inside chamber. Finally, temperature and humidity reading will show at HyperTerminal.
