The heart rate sensor: a thumb-sized heart rate monitor designed for Arduino microcontrollers; includes a Gravity interface for easy plug-and-play connectivity. The pulse sensor which is based on PPG techniques; a simple and low-cost optical technique that can be used to detect blood volume changing in the microvascular bed of tissues. SEN0203
Muscle Sensor Surface EMG Electrodes allow you to control your projects with your muscles. Adafruit 2773
The MyoWare Muscle Sensor is now designed to be wearable allowing you to attach biomedical sensor pads directly to the board itself. DEV-13687
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
The MyoWare Muscle Sensor measures, filters, rectifies, and amplifies the electrical activity of a muscle and produces an analog output signal that can easily be read by a microcontroller, enabling novel, muscle-controlled interfaces for your projects.
Arduino-powered, electromyography (EMG) sensor kit that provides you with a MyoWare Muscle Sensor, each shield developed here at SparkFun, and everything you need to connect them all together. KIT-13772
The MyoWare Power Shield is designed to take two standard CR2032 coin cell batteries to power the MyoWare Muscle Sensor. We have made this board in a way that the coin cell batteries are connected in parallel for extended capacity at a nominal 3.0V. DEV-13684
