ENC 28J60 ETHERNET LAN MODULE and Heart beat Sensor ENC 28J60 is tiny and convenient, you need to connect it with your Arduino board with 10 wires, then you can use it like the Ethernet Shield V1.0 for Arduino. The Heart beat sensor uses a bright infrared (IR) LED and a phototransistor to detect the pulse of a fingertip. A red LED flashes with each pulse. The IR LED lights up the top of the finger, and phototransistor on the bottom of the finger measures the light emitted. When the heartbeat pulses the resistance of the photo transistor will be slightly changed.

Force Sensor This is a small force sensitive resistor. It has a 0.16" (4 mm) diameter active sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the resistance. When no pressure is being applied to the FSR, its resistance will be larger than 1MΩ, with full pressure applied the resistance will be 2.5kΩ.

FINGER PRINT MODULE GT-511 C3 This is the updated version of the GT-511 which has an increased memory capacity. The module can store up to 200 different fingerprints and is now capable of 360° recognition. Reads and identifies fingerprints with an on-board optical sensor and 32-bit CPU. All you need to do is send it simple commands. The database of prints can be downloaded from the unit and distributed to other modules. As well as the fingerprint "template," the analyzed version of the print, you can also retrieve the image of a fingerprint and even pull raw images from the optical sensor. The on-board JST-SH connector has four signals: Vcc, GND, Tx, Rx. A compatible JST-SH pigtail is included. PINOUT: from LEFT to RIGHT = TX (3.3V level - black wire), RX (3.3V level), GND, VCC (3.3V to 6V) Price 1200 birr
