I need to record blood pressure with a blood pressure cuff interfaced to an Arduino uno module so the data can be logged. I searched the web for a such a device, but could not found anything useful.

Which modules should I look for?

    Are you looking to build a blood pressure monitor, or are you hoping for something pre-made?

    Not exactly i need to store blood pressure data on a server and monitor the results on a graph lively.So i need the data from the module but i don't need an external monitor i just need to store it.@Alphy31

    So you just want an input device you can write numbers to by hand?

    No i am measuring my blood pressure and the results are needed to be parsed and stored in database lively @Alphy13.And i need an Arduino module to measure it.My question is which modules should i look for.For example i found an air pressure measurement module but i need to measure blood pressure.

When I hear you ask for a module, I think of an Arduino "Shield" but you dont need one of these. You can connect what you need directly to the board, but it will be easier if you use a breadboard.

There is a really good paper here that describes the measurement process and even shows the low-pass amplifier they used to read from the pressure sensor. You can place only the sensor inside the inflated portion and have the rest outside, or you can use a full module that is placed inside the chamber.

You will also need an air pump to inflate, and a solenoid valve to deflate. Both the pump and solenoid use 12V, so you will need a set of relays. Make sure that you have a way to restrict the airflow out, so that it deflates slow enough to get precise measurements.


Government regulation of healthcare devices raises the entry cost to market for such devices, so it's no surprise none was found in my web search.

However, there's a non-Arduino Bluetooth blood pressure cuff which logs data to iOS and Android devices

You can also create your own following instructions in this book with a capacitive pressure sensor and a Mega 2560.
