The Heartbeat Sensor (Pulse Sensor) is a plug and play well designed heart – rate sensor used for live heart rate data for different projects with the help of arduino. It is an open-source app program through which you can put your heart rate in real time using graph displayed. The sensor can be worn on the finger or earlobe and can be connected with arduino.

Advancer Technology Muscles Sensor V3 measure muscle activity via electric potential. It is specially designed for microcontrollers with small form factor. The gain is adjustable with breadboard compatible. It is used in medical research, wearable/mobile Electronics, Powered Exoskeleton suits, controlling robots and many more. The muscle sensor receive electrical signal straight for the muscle through shrinking amplifier technology and puts it into the devices and make it work without buttons and joysticks.

This fingerprint sensor is for direct connections to the microcontroller. It has low power consumption, it has low in cost too. Basically, this sensor is small in size. It has excellent performance too. This device has professional optical technology. It has precise module manufacturing technics also. It has integrated image collecting and algorithm chip together attached to it.
