OpenHardwareExG: An open source platform for ECG, EEG, EMG, ENG, and EOG signal processing

The OpenHardwareExG project is aimed to develop an open source hardware and software platform for electrophysiologic signal processing applications, including ECG, EEG, EMG, ENG, and EOG. The current version of the design is based on an ADS1299 analog front end for capturing electrophysiologic signals and integrates an Arduino Due compatible microcontroller along with 5kV of reinforced isolation for safety.

Smart LED lighting system

This Application Note from Maxim describes the implementation of ambient light sensing, communication, and energy measurement into LED lighting systems for energy conservation and lower operating costs. It explores the critical design considerations of adding ambient light sensing, communication (both wireless and powerline), and energy measurement to LED lighting systems. Reference design examples are also presented. Ambient light sensing, communications, and energy measurement make up the critical components of an intelligent lighting system. Ambient light sensing allows lights to dim when other sources of light already light a space sufficiently. In addition, sensors that detect the color of ambient light
