Blood Oxygen Heart Rate Meter

Blood Oxygen Heart Rate Meter Using Arduino

This instructables show how to use MAX30102, XIAO and a tiny display to build a blood oxygen and heart rate meter. Step 1: Sensor & Algorithm This project use Maxim Integrated MAX30102 Biosensor to detect pulse oximeter and heart rate. However, the official sample is not so accurate, so will use the MolecularD algorithm instead. Ref.: https://www.instructables.com/Pulse-Oximeter-With-… …

GoFly – paragliding/hangliding/gliding altimeter-variometer from Your car navigation using Arduino

GoFly is a project based on PNA (car navigation devices with Windows CE), LK8000 tactical fligh computer software and variometer (altimeter) external input based on Arduino board and pressure sensor. Why? -You can build this for about 150$, -Your ordinary PNA (Personal Navigation Assistant) changes to really nice, high end flying computer, with lot of features and Arduino based altimeter …

Power Quality Meter

Power Quality Meter ( PQ Monitor) using Arduino

Arduino UNO project, Power Quality Meter, someone would call it’s PQ Monitor or PQ Analyzer. I had already published one  blog  devoted RMS voltage measurements on full band  20 – 20 000 Hz  audio signals. ( Following my own style, I’d refer to already published materials whenever it’s possible ).  This time measurements performed on single AC …

Oscilloscope Using the SainSmart Mega2560

Make an Oscilloscope Using the SainSmart Mega2560 with the TFT LCD shield and the 3.5 “color touch screen using Arduino

This instructable will show you how to build a portable Touch Screen Oscilloscope for less than 40 U$! The oscilloscope is one of the most powerful electronic instruments that is available to electronics hobbyist, experimenters, and engineers. It is mainly used to measue time-varying signals. Any time you have a signal that varies with time( …

FabECG: a simple electrocardiogram board using Arduino

Technologies for rudimentary physiological sensing are getting cheaper and easier to implement. Consider, for instance, these non-contact sensors from UCSD which can be used to take an EEG through hair or an ECG through a T-shirt! One can even make a simple oscilloscope to digitize, store and view the signal using only a Tiny45 micro-controller and a …
