Pulse oximetry is a non-invasive means for measuring blood oxygen saturation and pulse rate, with typical sensors based on rigid electronics. Here, the authors develop a pulse oximeter based ...

The first is an attempt to make his own pulse sensor. The second is a miserable experience with a cheap Bluetooth Low Energy module.

As the name suggests, the Pixel Watch 3 can detect the absence of a pulse while it's being worn on your wrist. It does this using the same optical sensors that are used to measure your heart rate.

The pulse oximeter can measure and display pulse rate simultaneously with the SpO 2 level. This is a non-invasive, real-time technique particularly in vital sign monitoring during an operation or ...

Using a sensor for something other than its intended purpose is exactly what [Zach Halvorson] did to make the Roast Vision device, which uses the MAX30101, a sealed optical sensor intended mainly ...
