2022-09-27Do you know the difference between LED and incandescent lamps?
Incandescent LAMP WORKING PRINCIPLE IS ELECTRIC CURRENT THROUGH THE filament to produce heat, spiral filament will constantly gather heat, make the temperature of the filament amounts to 2000 degrees Celsius above, filament in incandescent state, like burning red iron can light up and give out light. LED lights, also known as light-emitting diodes, are solid-state semiconductor devices that convert electricity directly into light.
2022-09-21Do you know what the DIP Switch is in motion sensors?
Dip switch is mostly used in the program control plate to control the performance of components. So dip switches will also be called according to the industry sector: program switch, address switch, and the most familiar DIP switch. Dip switch, as a micro switch that needs manual operation, is widely used in communication, security and many other equipment products. Most DIP switches use in-line (DIP) to transform between the two states, and then according to the different bits of the composition of 2 N power of different states, to achieve different functions.
2022-09-14Precautions for installation and use of microwave sensor
The respective advantages of microwave sensor and infrared sensor, in the detection accuracy, adaptability to the environment, penetration and life, microwave has incomparable advantages. Therefore, the application of microwave induction is more and more common, in addition to the field of lighting, but also widely used in the system control, the Internet of things and other fields.
2022-08-31What do you know about hunman body motion sensors?
Due to the change of temperature, pyroelectric crystals and piezoceramics will appear on the structure of the charge center relative displacement, so that their spontaneous polarization strength changes, so as to produce different signs of bound charge at their ends, this phenomenon is called the pyroelectric effect.
2022-08-23Infrared detectors need to be routine maintenance and security protection
Infrared detector in daily work, because work outdoors for a long time, thus inevitably affected by dust in the atmosphere, microorganisms, and snow, frost, mist, in the past, for a long time in the detector of the outside wall scale tend to accumulate a layer of dust samples, also will grow in a wet place a thick layer of moss moss, sometimes birds pull excrement to the infrared detector,
2022-08-17Digital zero technology
Do you know anything about zero technology? The purpose of the digital zero-crossing upgrade is to make accurate calculations to ensure that each relay can be opened at the zero of the sine wave.
