Abstract
Water is essential for life, and its safety is crucial for human well-being. This water body monitoring system utilizes the STM32F103 microcontroller as its core control unit. It achieves temperature detection via the DS18B20 sensor, malodorous H2S gas detection using an H2S sensor, and turbidity measurement through the TSW-30 sensor. Should any of these parameters exceed predefined thresholds, an alarm is triggered by a buzzer. The system's parameters are displayed locally on an LCD and transmitted to a mobile app via a WiFi module based on the ESP8266. This allows users to monitor water conditions through their mobile devices. The development of this system involved schematic design, programming, physical assembly, and functional testing, successfully meeting the intended functional objectives.
