Pulse Oximeter and Heart Rate Meter

January 15, 2013 By: admin Category: AVR, Measurement, Monitoring, Project No Comments →

The purpose of the project is to build a low cost pulse oximeter and heart rate meter powered by solar energy. The idea based on the fact that the oxygen saturation of blood is one of the most important parameter to be monitored. By make it low cost and solar powered, the device is ideal […]

Remote Control Tester

June 18, 2012 By: admin Category: Remote, Renesas No Comments →

The purpose of this project is to build a device that can capture the Infrared (IR) signal transmitted by all types of remote controls. It can capture IR codification signal at the modulation frequency level. This device not only simply captures IR signal, it also can decode this IR signal. Telling us what codification is […]
