Abstract. Monitoring the health of pregnant women is essential for promoting a safe and successful pregnancy. This paper presents the development of a monitoring system using the ESP32 microcontroller, along with the MAX30205, MAX30100, and BME680 sensors. The ESP32 acts as the core unit for data collection and transmission. The MAX30205 sensor provides precise real-time temperature readings, while the BME680 measures key environmental factors such as humidity, pressure, and gas resistance. Additionally, the MAX30100 monitors pulse rate and blood oxygen levels. Together, these sensors enable comprehensive health monitoring for pregnant women.
