| Abstract: | The paper studies the design and implementation of temperature and humidity monitoring based on AM2303 module, focusing on hardware and software structure and micro-controller and single-bus communication protocol of data acquisition and TFT-LCD display. AM2303 temperature and humidity data acquisition module and STM32F103VBT6 processor as the core when designed the system which is provided with the temperature and humidity data acquisition, display, alarm function. Collect data and alarm information display through the LCD in real time; adjust the pulse width modulation duty cycle to control the heating circuit relay off time to achieve the closed-loop control of temperature. The system is simple, low cost, and easy to expand. |
