Single Lead Heart Rate Monitor - heart rate monitor with AD8232

SparkFun Cab-12970

A module with an EMG sensor that detects the activity of human muscles and neurons. Generates an analog signal in the range from 0 to 3 V on the output, it does not require the use of a conductive gel. DFRobot SEN0240

Disposable biomedical electrodes that allow you to perform experimental ECG measurements. DFRobot FIT0510

Iduino SE049 is a simple and functional heart rate sensor, ideal for educational and hobbyist projects in the fields of electronics and bioengineering. Thanks to its compatibility with Arduino and intuitive operation, it allows for the creation of custom measurement devices such as pulse meters or smart health-monitoring wristbands. It is suitable for mobile and stationary applications as part of a diagnostic or training system.

Muscle Sensor Surface EMG Electrodes allow you to control your projects with your muscles. Adafruit 2773

The sensor responds to chakra changes in the tissues by analyzing the reflected light (the module contains an illuminator and a sensor).

Finger Vein Scanner Module (B) is a thin, energy-efficient biometric module with finger vein detection based on a Cortex-M4F microcontroller, designed for precise user identification in security applications. NIR technology enables effective recognition regardless of the skin surface condition, making the module a reliable alternative to traditional fingerprint readers. Thanks to its compact dimensions and a rich set of accessories, it facilitates integration with smart locks, door handles, access control systems, and compact IoT terminals.

Module with a pulse sensor (heart rate). The board is equipped with a Grove connector and a digital output in the form of pulses. Seeed Studio 101020033

Heart rate measurement module compatible with Arduino and Raspberry Pi (Gravity: Heart Rate Monitor Sensor For Arduino). It uses PPG technique, which in a simple and cheap way is able to measure the changing volume of blood. DFRobot SEN0203

Heart rate monitor module based on the MAX30102 chip. Powered with the voltage from 3.3 to 5V, communication via the I2C interface.

Module with heart rate sensor, SpO2 (oxygen saturation) and smoke levels. It is based on the MAX30101 chip and communicates via the I2C interface. Pimoroni PIM438

The module with the MAX30100 chip that monitors the oxygen content in the blood and the heart rate. It consists of two LED diodes, a photodetector, optimized optics and low noise analog signal processing. modMAX30100

Module with pulse and SpO2 level sensor (oxygen saturation level). The module is based on the MAX30102 chip and communicates via the I2C interface.

Designed to pair with the MyoWare Muscle Sensor; 10-segment bar graph shows the magnitude of the measured signal. The more muscle activation measured, the higher up the board the lit LEDs will go. DEV-13688

Module with GSR skin resistance sensor. It is used to measure skin activity, which reflects the stress response and experienced emotions. The board is equipped with a Grove connector and communicates via an analog interface. Seeed Studio 101020052
