In many applications loss of battery power is a problem causing no real harm. But, this is not the case in radio control (R/C) model aircraft. If the aircraft batteries “go dead” in flight it generally results in total destruction of the model and can represent a safety hazard.

Mains Voltage Monitor

The purpose of mains monitor project is to record mains fluctuations with an autonomous device and upload measurement to a PC for analysis. The monitor plugs into an ordinary mains outlet and records (time stamps) the voltage amplitude and the frequency at defined time interval. It transmits data through an USB interface. It can [...]

The project built to track cats. It will log when they go in and out of the house. You can see what cats favorite time to go out is. The project can sent SMS messages if a cat goes missing for a certain amount of time.

Ultrasonic Radar For Driver

February 08, 2010 By: admin Category: AVR, Monitoring Project, Project No Comments →

This AVR-based embedded system of high-resolution ultrasonic radar will help the driver to avoid potential accidents by telling the driver the minimal distance of obstacles behind the car which may be neglected by drivers. The system uses TV On-screen character display (OSD) technology as main display and LED as secondary display. In the light-emitting bars [...]

Remote Critical Area Monitoring System

February 02, 2010 By: admin Category: Microcontroller, Monitoring Project, PIC, Project No Comments →

This is a video based remote environmental monitoring system for use in critical areas. The system enables you to connect remotely to a web page and obtain video image of the environment, temperature, mains power failure state, monitor the voltage of the backup battery, and monitor door contact state.

Automatic Water Valve-Meter

February 01, 2010 By: admin Category: AVR, Measurement, Microcontroller, Monitoring Project, Project No Comments →

The project convert a standard residential water meter as an inexpensive industrial flow meter. To accomplish it, you need to remove the register of standard meter and adding a PCB to the top with a hall effect sensor to pick up the rotation of the internal impeller which has an embedded magnet that normally drives [...]

FM Receiver, ATmega8

January 30, 2010 By: admin Category: AVR, Microcontroller, Monitoring Project, Project, Wireless No Comments →

The purpose of ATMEGA8-16P1 based FM receiver project is to monitor polar orbiting weather satellites operated by the National Oceanographic and Atmospheric Administration (NOAA). The receiver will tune from 60 to 800 megahertz with an IF bandwidth of 50 kilohertz. While the IF bandwidth was chosen to be optimal for the NOAA polar orbiting weather [...]
