Abstract
This study describes the design and implementation of a dependable and reasonably priced environmental monitoring system that uses a Raspberry Pi and a Sunrom Model #1211 sensor to measure temperature and humidity. The system is designed for use in fields where real-time monitoring is essential, such as climate research, industrial automation, and agriculture. A MAX232 IC facilitates RS232 networking, which guarantees reliable data transfer and steady voltage-level conversion. The Python program gathers and processes sensor data at regular intervals using the pySerial library. The system's real-time feedback capability, modular design, and verified accuracy—obtained by comparison with a digital thermo-hygrometer (HTC-2) of commercial grade—are among its main advantages. The system is a scalable and effective tool for gathering environmental data because of its architecture, which facilitates simple integration with extra sensors and can be modified for deployment in various environments.
