Wireless Human Health Monitor
The aim of this ATmega644-based project is to build a portable device implementing wireless technology and taking full advantage of the wide-spreading Internet to provide a convenient solution to monitor human health.

Energy Monitoring Transmitter
This energy monitoring transmitter, known as emonTx, is an Atmega328-based small wireless energy monitoring node. It also fully compatible with Arduino IDE. EmonTx is designed to take inputs from multiple CT sensors, optically from a pulse-output utility meter and from multiple one-wire temperature sensors. The design is based on the JeeNodeV5 by Jean-Claude Wippler and [...]
PIC Power Line Monitor
This project is built to monitors the instantaneous current, voltage, frequency, and real power consumption in home. To monitor voltage, the project uses a dedicated miniature transformer. Current is measured using a home built current transformer that clamps around the incoming power feed. The current transformers are homemade from split ferrite cores with 100 turns [...]
AVR Power Usage Logger
This ATmega168-based project monitors household power usage and logs it to an SD card. Signals from voltage and current detectors amplified LMC6484AIN quad op-amp and then AVR microcontroller computes the power consumption using the formula P=VxI.
