Im building a wristband heart rate monito, i woul like to use PPG but as you may know measuring the blood flow on the wrist is very difficult because of the external noise, there are many factors involves trying to measure the heart rate on the wrist, the first one is the ambient light, muscle signals, tisue signalas and the most important the movemente signal.. this wristband will be used for people who is always in movement, so we need to reduce the noise produced by the movement also or i dont know... i let you here these files you can check, the one calle "good" is a very insteresting article, i think it has all the information but i didnt get that because im not as good in electronics. On the document you will find all the electronics schematics, so maybe you can bring them all together and do just an schematic that will work for this application.. also there is another concept called analog Front End, does this Ic called AFE4400 does the same thing as the document that im ataching?

Dear Client, Hope you are doing great. Thanks for the project post and providing an opportunity to bid upon. It is my immense pleasure to submit my proposal for this project as I am an experienced product designer with more than 5 years of experience. Furthermore, I have worked successfully in designing a similar product in past. As per my understanding, the scope of this project is to design a heart rate monitor, which can get the details from photo resistor based sensor. This may require an amplifier like AFE4400. But as per my understanding, we can think of avoiding this. I have a good reason behind this. We can interface the sensor working on 3.3 Volt directly with ADC of micro-controller like Atmega328. The Micro-controller can process the data and give the result desired format. However, using AFE4400 is good for precision heart rate monitor estimations. This can be interfaced with micro-controller through SPI. The estimated heart rate is captured by AFE4400 and it is processed in MCU. Furthermore, we can display the output in small OLED. seven segment display, etc. The data can also be transferred using the Bluetooth or stored inside SD card. The device can have small charging unit and can be charged through USB. I will provide you the complete design files, which will include PCB files, Gerber files, schematic, Bill of materials, codes, etc. Thanks in anticipation. Kind regards; Amit
