The system utilizes the MAX30102 sensor to measure hemoglobin levels and a temperature sensor to record body temperature without requiring any blood samples. A slide switch allows users to select gender, enabling gender-based diagnostic interpretation. By using slide switch, we can select the gender.

The acquired sensor data is processed by the Arduino Uno and displayed in real time on an LCD screen, providing both hemoglobin concentration and body temperature. The system also integrates an ESP8266 Wi-Fi module, which uploads the readings to the ThingSpeak cloud platform for remote monitoring and data visualization. The power supply circuit converts 230V AC to a regulated 5V DC output through step-down transformation, rectification, filtration, and regulation stages to power the components safely.

When a user places a finger on the sensor, the system detects the hemoglobin and temperature levels, displays diagnostic messages, and logs the data on the ThingSpeak dashboard along with timestamps and gender information. This IoT-based non-invasive diagnostic tool enables easy, continuous, and contactless health monitoring, making it suitable for home-based screening and early detection of hemoglobin-related conditions.
