This is a simple WiFI Smoke Detector that texts me when it senses smoke. I made this for my battery storage area in case of a lithium polymer fire. I still have all of my regular smoke detectors installed and I don’t suggest relying only on this, but rather as an extra layer of protection. […]

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

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

OSI Optoelectronics’ detector-filter combination series incorporates a filter with a photodiode to achieve a tailored spectral response in a multitude of standard and custom combinations. All detector-filter combinations can be provided with a NIST traceable calibration data specified in terms of amps/watts, amps/lumen, amps/lux, or amps. The PIN-10DF is a 1 cm2 active area, BNC package detector-filter combination

DDC’s HSN-1000 radiation-hardened Hybrid Nuclear Event Detector (NED) senses ionizing radiation pulses generated by a nuclear event, such as the detonation of a nuclear weapon, and rapidly switches its output from the normal high state to a low state with a propagation delay time of less than 20ns. The active low Nuclear Event Detection signal (NED) is

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
