Pulse Sensor Heart Rate Sensor

The Pulse Sensor Amped is a plug-and-play heart-rate sensor for Arduino. It can be used by students, artists, athletes, makers, and game & mobile developers who want to easily incorporate live heart-rate data into their projects.It essentially combines a simple optical heart rate sensor with amplification and noise cancellation circuitry making it fast and easy to get reliable pulse readings. Also, it sips power with just 4mA current draw at 5V so it's great for mobile applications. Specifications: Operating Voltage: +5V or +3.3V Current Consumption: 4mA Inbuilt Amplification and Noise cancellation circuit. Diameter: 0.625” Thickness: 0.125” Thick
