2022-10-19The difference between a heat detector and a smoke detector
In fire management, we often use smoke sense and temperature sense, so what is the difference between smoke sense and temperature sense? Where is it often installed and used?
2022-10-12Does the induction light need to be switched on and off？
Induction lamp is a kind of lamps and lanterns, relative to other lamps and lanterns, induction lamp can be said to be a new type of intelligent lighting lamps and lanterns, it is used in some public places, and now for convenience is also used in home life, the use is convenient and save. But for the induction lamp installation, many people will have questions, that is, the induction lamp need to switch?
2022-10-12Common induction lamp introduction
Human body induction lamp: its working principle is the automatic control products with infrared technology, when people enter the induction range, the sensor will automatically detect the infrared spectrum of the human body, and then according to the different spectrum to connect.
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.
