There is two based meter one for distribution line and one for the
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-…

Spirometers are the classical instrument to perform the parsing of air as it is blown out of your mouth. They consist of a tube that you blow into that records the volume and speed of one breath which are then compared to a set of normal values based on height, wt and sex and are

Hello friend, welcome back after a long break. Earlier I have posted an Instructables on Arduino Energy Meter which was mainly designed to monitor the power from the solar panel (DC Power) in my village. It became very popular on the internet, lots of people all over the world have built their own. So many students have

The ArduMeter is an Arduino Based Multimeter, which many people have made to perform different operations, and searching on google you could find all the variety of things it can do. I wanted to make one that is portable, quite easy to use, give decent readings to a certain extent, and of course can help
