Use a biosensor for healthcare apps
- [Instructor] There are many kinds of sensors on a market, including the biosensors that can be used in a broad range of applications such as healthcare, medical analysis, bacteria detection and environmental monitoring. Let's take a look at the popular fitness, or activity trackers that can measure our heart rate and the pulse oximetry. On your fitness tracker, there may be an electronic circuits board like this one. While a biosensor can be used as peripheral device connected to the serial communication port of your microcontroller. Let's look in the biosensor sensor used by the fitness trackers here. There are many choices on the market. Here I just picked a integrated heart rate, and a pulse oximeter sensor named MAX30102. If we open the data sheet of this sensor, we can see some highlights from the system diagram on the first page, such as the hardware components including the I square C communication port used for communicating with our applications. First, let's check the…
