Ionization Smoke-Detector With Programmable Calibration schematic

Ionization Smoke-Detector With Programmable Calibration

Microchip Technology unveiled the RE46C180—the world’s first Ionization Smoke-Detector IC with programmable calibration and programmable feature selection, and the first with horn synchronization and auto alarm locate. This Ionization Smoke-Detector ASIC also has expanded options for implementing hush operation, and more options for interconnect operation—including with carbon-monoxide detectors. These features enable designers to develop and …

Cell Phone Detector

Project Summary This is a mobile phone sniffer circuit that can detect the signals being used in the GSM (Global System for Mobile Communication) band at about 900 MHz. Since the signals are digitally encoded, it can detect only the signal activity, not the speech or the message contents. A headphone is used to hear …

70W soldering iron controller

70W soldering iron controller

Theory of operation In series thermocouple soldering iron have a thermocouple in series with their heating element and thus only have two connections (actually one more which is electrically connected to the tip for ESD purposes). When a voltage is applied to the two terminals the tip heats, when unpowered the thermocouple voltage can be …
