The circuit was specially designed for shop windows animation as it makes use of a capacitive sensor that is triggered by touch control system. BC337 – a small signal NPN Silicon AF medium power ...

Capacitive touch sensors are based on the electrical capacitance of the human body. When, for example, a finger comes close to the sensor, it creates a capacitance to Earth with a value of 30 to 100 ...

With so many cell phones, PDAs, and MP3 players using touch-sensitive keypads, wheels, and screens for user input, regular mechanical pushbuttons are beginning to seem outdated. Even so, mechanical ...

ON Semiconductor has introduced a highly integrated capacitance-to-digital converter IC that will speed the implementation and reduce the component count of electrostatic capacitance touch sensor ...

Tick tracer. Glow meter. Sniffer. They go by many names, but capacitive voltage sensors are all designed to do one thing: detect the presence of voltage in a wire or piece of equipment without ...

According to several recent Embedded Market Surveys, 65 to 70 percent of the developers who responded said they use more than one microprocessor or microcontroller in a single design, but only 4 to 7 ...

Today’s homes and workplaces are increasingly pervaded by smart appliances, which are designed to be attractive and reliable, and ideally should support interactions that are as easy and rewarding as ...

• Trapped acoustic resonance is most simply described with an analogy: the ringing of a bell. • Microprocessors control the frequency of the mechanical resonance and monitors its decay. • A thicker ...
