| dc.description.abstract | Environment sensors are widely used with including microprocessor and microcontroller in the world today. This project is about the development of microcontroller based environment sensor for measuring temperature. The PIC18F46K20 microcontroller is a low power utilizing high performance RISC architecture. Design implementations for hardware and software are important. The schematic and also layout for PCB is done by Proteus and Eagle software. MicroCode Studio Plus and PICBASIC PRO compiler software are used for writing and compilation code BASIC language. The MCP9700, sensor by Microchip is an analog temperature sensor and used to sense the temperature. The voltage output pin is directly connected to an Analog to Digital Converter (ADC) input of the microcontroller. The range of temperature is from -40 °C to +125 °C. The 3.3 V power supply is used to operate PIC board and sensor circuit board. The ADC reads the data at pin 9/AN6 and then converts the data into decimal value. The data is not in temperature value and an equation has to be implemented to produce the temperature value. Then the temperature will be displayed on LCD and HyperTerminal in degree Celsius. However, the temperature measurement shows some errors when compared with SHT75 sensor that used as a reference temperature. As the desired output and result have been obtained, all of the objectives have been met. | |
