Mini Fingers Measuring Detect Heartbeat Sensor Module For Arduino
 Features:
This project uses bright infrared (IR) LED and a phototransistor to detect the pulse of the finger, a red LED flashes with each pulse
Pulse monitor works as follows: The LED is the light side of the finger, and phototransistor on the other side of the finger, phototransistor used to obtain the flux emitted, when the blood pressure pulse by the finger when the resistance of the phototransistor will be slight changed
We chose a very high resistance resistor R1, because most of the light through the finger is absorbed,it is desirable phototransistor sensitive enoughResistance can be selected by experiment to get the best results
The most important is to keep the shield stray light into the phototransistor For home lighting that is particularly important because the lights at home mostly based 50HZ or 60HZ fluctuate, so faint heartbeat will add considerable noise
Module: Heartbeat Sensor
Compatible with Arduino
Size:19 x 15cm

ADS1015 12 bit precision analog-to-digital converter ADC module development board
For microcontrollers without an analog-to-digital converter or when you want a higher-precision ADC, the ADS1015 provides 12-bit precision at 3300 samples/second over I2C The chip can be configured as 4 single-ended input channels, or two differential channels As a nice bonus, it even includes a programmable gain amplifier, up to x16, to help boost up smaller single/differential signals to the full range We like this ADC because it can run from 2V to 5V power/logic, can measure a large range of signals and its super easy to use It is a great general purpose 12 bit converter
The chip's fairly small so it comes on a breakout board with ferrites to keep the AVDD and AGND quiet Interfacing is done via I2C The address can be changed to one of four options (see the datasheet table 5) so you can have up to 4 ADS1015's connected on a single 2-wire I2C bus for 16 single ended inputs
