PPG stands for Photoplethysmograph, which is a medical device used to measure the amplitude, frequency and other bio-signal parameters through diffused light of an LED light source. As an interface device, it can be connected to various types of hardware and software for further development and application. In this article, we will discuss the 821024PPG application field and its working principle.

The 821024PPG is a multi-channel PPG device with a range of features that make it suitable for many different applications. It is the perfect solution for medical applications like sleep research, hearing aid consultancy, optical diagnostics, and electrocardiography. Due to its accurate and reliable performance, the device is also suitable for a wide range of sports and fitness activities like swim tracking and real-time data analysis.

In terms of functionality, the 821024PPG offers a variety of settings and options, including multiple channels, high frequency response, and low noise operation. Its automatic gain control feature ensures accurate readings even in low light conditions. It also has a wide range of connections and protocols, such as USB, I²C, GPIB, and RS-232.

So what’s the working principle of the 821024PPG? The device is capable of measuring the frequency and amplitude of small changes in blood volume via diffused light from an LED light source. The emitted light enters the tissue and is reflected back to the photodetector. The photodetector is then able to convert the intensity of the reflected light into an analog or digital signal. This signal can then be analyzed by a variety of software applications or transmitted to other devices.

In conclusion, the 821024PPG is a multi-channel interface device designed for a variety of applications. It is capable of measuring the frequency and amplitude of small changes in blood volume via diffused light from an LED light source. Thanks to its wide range of settings and connections, it can be connected to various types of hardware and software for development and application.
