Gas sensors are employed in a wide range of applications in the fields of safety, health, instrumentation etc. Common examples are domestic/commercial alarms for explosive or toxic gases, or in automotive application as gas leakage detectors for LPG powered cars and exhausts detectors inside any fuel-powered truck/car. Such sensors, nowadays, are found also in [...]
SAMEgen is a small test generator for the National Weather Service’s Specific Area Message Encoding (SAME) coding and may find use in both development of decoding circuitry and in testing SAME-enabled receivers. SAME is used by the NOAA Weather Radio (NWR) broadcasts and the Emergency Alert System (EAS) to disseminate weather watches, warnings, and [...]
I’m sure that everyone has alarm clock in their house from the simple to the elaborate, to help them get a start on the day. But you need to be there to set it. DJ Delorie has design Multifunctional Alarm Clock that has three primary features: automatic time setting on power-up, remote management and [...]
The Witness Camera is automated AVR Camera Security System that has self-recording feature and a gigabyte-class flash card as recording media. Witness camera project build because available surveillance solutions were too expensive or impractical for home use. The project system built from a VGA CMOS color camera, an microcontroller avr ATmega32, a passive-infrared (PIR) movement [...]
PIC GSM SMS Alarm is a electronic project by trax tha has capability to sendi SMS when alarm triggered. It use Siemens GSM phone as sms sender and PIC 16F84A as main processor. The project has 5 inputs so it can send 5 different SMS messages. Trax said that when alarm condition happens each sensor [...]
