This compact mains voltage sensor is intended to monitor and signal to another circuit, for instance a microcontroller, about the presence and/or absence of the ac mains voltage. For this task, a ...

Need a Hall sensor? A strip of copper, a strong magnet, and an LM358 are all you need to explore the Hall effect hands-on.

Electric motors that are either poorly maintained or which lack the proper electrical protection are the second greatest cause of electrical fires. So says the Factory Mutual Research Corp., a ...

Designed specifically for high-voltage sensing, a new generation of optically isolated amplifiers make monitoring and system protection circuits more accurate and easier to design. These iso-amps can ...

This fire sensor circuit exploits the temperature sensing property of an ordinary signal diode IN 34 to detect heat from fire. At the moment it senses heat, a loud alarm simulating that of Fire ...

Many industrial and medical applications use instrumentation amplifiers (INA) to condition small signals in the presence of large common-mode voltages and DC potentials. The three op amp INA ...

Researchers from Pakistan's Ghulam Ishaq Khan Institute of Engineering Sciences and Technology have created an online algorithm to measure open-circuit voltage in PV systems that is claimed to be able ...

CMOS voltage reference circuits are integral to modern electronic systems, providing a stable and reproducible voltage that underpins the performance of myriad integrated devices. These circuits ...
