The circuit has been designed to produce a window switch with the use of a thermistor for the main purpose of sensing temperatures. Thermistor – one type of resistor used as temperature-sensing ...

The circuits were designed to illustrate the functions of two switches with the use of a single op-amp to show the operations of a precision light sensitive switch and a differential switch. LM741 – a ...

Aqara makes a range of HomeKit-compatible smart home devices for multiple regions around the world. This review takes a look at four of Aqara's latest products, including its Temperature and Humidity ...

Liquid-level switches used in aircraft, nuclear-power plants, medical equipment, and other critical applications must be precise and reliable. For that to happen, design engineers must know the ...

The signal attenuates severely when passing through air, but the presence of liquid greatly enhances transmission. Thus signal strength of the ultrasonic burst serves as the sensing mechanism. Upon ...
