Abstract

Currently, soil moisture monitoring is only done manually, which is less accurate, even though sometimes we need a soil moisture monitoring tool to determine the soil water content in plants. This research uses a Soil Moisture sensor to measure soil moisture and the NodeMCU ESP8266 microcontroller as the main controller. The system is designed to provide accurate and efficient soil moisture monitoring through the Internet of Things (IoT). The integration of Blynk as a monitoring application offers easy access to real-time soil moisture data via mobile devices. This system is designed to help users monitor soil moisture in real-time using NodeMCU as the main platform and Blynk for user interaction. Through this system, it is expected that users can avoid the risk of water shortages by knowing the soil water content in real-time. Based on testing, this soil moisture monitoring product has a success rate of 88.2% for soil moisture accuracy and an average user satisfaction rate of 60%.

Abstract

Health is a crucial aspect of human life that must be maintained and monitored regularly, especially during recovery periods or self-isolation. Real-time and remote body monitoring has become an essential need in today’s digital era. This study aims to design and develop a heart rate and blood oxygen saturation monitoring device based on the Internet of Things (IoT) using the NodeMCU ESP8266 microcontroller integrated with the MAX30100 sensor and the Blynk application. The research method involves the design of an electronic system based on microcontrollers, software programming, and direct functional testing. The test results show that the device is capable of accurately detecting heart rate (BPM) and oxygen saturation (SpO2), displaying the data on a 16x2 LCD, and transmitting it to the Blynk application in real-time via a WiFi connection. Therefore, the developed device has proven to function effectively as a practical and portable remote health monitoring system.
