However, such sensors are too expensive where the accelerometer is used. Accelerometer is very sensitive and can be used to make Earthquake detector circuit. But, there are few dedicated and cheap ...

It’s even complete with 3D printed enclosure and sensor elements. [Juangg] designed it to use three sensors: a pulse sensor, a breath sensor, and one to measure Galvanic Skin Response (GSR).

After some searching, I ended up using a microcontroller and a piece of code borrowed from the web that I tweaked and adapted. The microcontroller-based concept was chosen because I wanted to scale ...

Circuit Diagram & Working Explanation After calling for header we don't need to worry for establishing communication between Arduino Uno and BMP180 sensor. We can simply call in special functions ...

For patients to receive good care, doctors must be present. To administer medication or provide treatment, he can’t be everywhere at once. If we regularly examine our health, we may be able to ...
