MICROCONTROLLER BASED SYSTEM FOR TEMPERATURE AND HUMIDITY CONTROL

V prvem delu diplomskega dela je na kratko predstavljena zgodovina merjenja temperature in temperaturne lestvice. Podrobneje so opisani ključni elektronski elementi, ki smo jih uporabil in sicer senzor za merjenje temperature in relativne vlažnosti SHT75, mikrokrmilnik PIC16f648a, štirivrstični zaslon LCD, napajalnik Traco Power ter programska oprema MikroC, Altium Designer in PICkit2. V zadnjem delu diplomskega dela je prikazana električna shema, 3D model vezja, izdelava tiskanine , opis delovanja programa z diagramom poteka ter samo preiskušanje vezja in naše ugotovitve.The first part of my diploma thesis consists of a brief history of temperature measurement and basics of the temperature scale. Key electronic components, that have been used in my work are then described in detail, namely a temperature and relative humidity sensor SHT75, microcontroller PIC16f648a, a 4-line LCD display, power supply Traco Power and software equipment MikroC, Altium Designer and PICkit2. In the last part of the diploma thesis the electrical scheme and 3D model of the circuit can be found, together with the description of circuit creation, a description of the program with a flowchart and the results of the circuit testing
