Biomedical Sensors

What are Biomedical Sensors?

Biomedical Sensors are electronic components that detect physiological signals from the human body and convert them into electrical signals a microcontroller can read and process. Each sensor targets a specific body parameter like heart rate, blood oxygen saturation, muscle electrical activity, or fluid pH. A common example in Indian college biomedical projects is using the AD8232 ECG module to capture and display heart electrical activity on an Arduino connected serial plotter.

Biomedical Sensors Available at StemVolt

• AD8232 ECG Sensor Module — Captures heart electrical activity through skin electrodes, outputs analog signal to Arduino
• MAX30102 Pulse Oximeter Heart Rate Sensor — Measures blood oxygen saturation and heart rate using infrared and red light reflection
• EMG Muscle Sensor Module — Detects muscle electrical signals for gesture control and rehabilitation monitoring builds
• Analog pH Sensor Module — Measures fluid pH levels through analog voltage output for biomedical and water quality projects

How to Choose the Right Biomedical Sensors

Match the sensor to the specific body parameter your project needs to measure. For heart activity monitoring, AD8232 ECG module is the standard choice for Arduino-based builds. For blood oxygen and heart rate in one package, MAX30102 uses I2C and fits compact wearable designs. EMG sensors output analog voltage and need an ADC pin on the microcontroller. One practical tip: always use shielded cables and keep the microcontroller away from the sensor electrodes during ECG measurement, as nearby digital noise directly corrupts the signal quality.
