SparkFun Biomedical sensor pad set 10pcs

Sparkfun sensor  MyoWare® 2.0 from Advancer Technologies is a newer version of this producer's bestseller. The MyoWare 2.0 muscle sensor included in this kit has been redesigned from the ground up with a new compact and easy-to-use design, and has been updated with the latest, most advanced chipset to improve sensor performance and reliability. In addition, MyoWare has developed a range of shields that work with the sensor (in our LED shield offering, displaying sensor readings as LED lights).

This detection module that allows you to detect your heart rate and blood oxygen level from your Arduino project. You can monitor your blood oxygen level yourself to avoid going to the doctor or pharmacy on purpose. Simply press the sensor with your finger and wait for the reading of hemoglobin (Spo2), heart rate and Perfusion Index (PI%). It is a solution as an integrated heart rate sensor and pulse oximetry, which includes two LEDs, a photodetector and is optimized for analog low noise optics.

Microwave radar presence and motion sensor using FMCW technology, compatible with Arduino and Raspberry Pi.

This detection module combines a phototransistor and an LED that, when placed on a finger or ear lobe, provides a reading.
By reading this signal you can interpret a change in the signal as a heartbeat.
Keep in mind that this is a sensitive module and you will experience the noise from home lights and other sources, since minimizing the lighting of the unit will help get the readings.
Heartbeat sensor Arduino features:
- Connection pins:
- S: Analog output
- (+): Power supply 3-5 VDC,
- (-): GND.
- Length: 18mm,
- Width: 18mm,
- Height: 4mm,
- Operating temperature: -40ºC to + 85ºC.

The DFRobot heart rate monitor sensor (SEN0213) is used to measure the electrical activity of the heart.

Stylish smart scale with tempered glass platform with heart rate measurement and 12 body analysis functions. Compatible with the Tuya Smart App (iOS 8.0 or higher, Android 6.0 or higher). Easy-to-read LED display.

This is the MyoWare Muscle Sensor Development Kit, an Arduino-powered electromyography (EMG) sensor kit that gives you the MyoWare, each MyoWare Shield and everything you need to connect them all together.

With this small and simple device, you can control your blood oxygen level yourself to avoid going to the doctor or pharmacy on purpose. Simply insert your finger and wait for the reading of haemoglobin (Spo2), heart rate and Perfusion Index (PI%). The heart rate is also graphically displayed. 

You can rotate the screen to see it in its 4 positions. High precision device, with low power consumption and automatic shutdown.
