Automated measuring and control of temperature and illumination of living space

U ovome radu projektiran je i izrađen prototip uređaja koji mjeri temperaturu i relativnu vlažnost putem integriranog senzora HDC2080. Pored te dvije fizikalne veličine uređaj mjeri i osvijetljenost prostora uz pomoć analognog senzora (fototranzistora) TEMT6000X01. Sustav je baziran na mikrokontroleru STM32L422CB, a programska podrška je pisana i uhodavana u STM32CubeIDE okruženju. Uređaj kontrolira temperaturu upravljanjem dvokanalnim relejnim sučeljem. Upravljanje osvijetljenošću izvršava paljenjem različitog broja svjetlećih dioda u LED traci. Izmjereni se rezultati prikazuju na E-ink (1,54'') pokazivaču, a pored toga ih se Bluetooth komunikacijskim sučeljem šalje na računalo. Na računalu se podaci ispisuju u aplikaciji sa grafičkim korisničkim sučeljem. Računalna aplikacija izrađena je u Visual Basic programskom jeziku u okviru platforme Visual Studio 2010.In this master thesis, a prototype of temperature and relative humidity measurement device is designed and manufactured based on integrated HDC2080 sensor. In addition to the physical quantities previously mentioned, the device also measures the ambient light by using an analog sensor (phototransistor). The system is based on STM32L422CB microcontroller and its software is developed in STM32CubeIDE environment. Temperature management is carried out through control of a two-channel relay interface module. Management of light intensity is performed by controlling LED strip. Measurement results are displayed on an E-ink (1,54") display and sent over Bluetooth communication interface to a computer. Received data is displayed on the computer in a desktop application. The desktop application is developed in Visual Studio 2010 IDE using the Visual Basic programming language
