1. The wire of the DC power supply should be as thick as possible, generally, the wire thickness is more than 20mil.2. The filter capacitor should be as close as possible to the VDD pin of the chip.3....
The main application areas of Fresnel lens at the present stage include projection and solar photovoltaic fields. Because the edge of the light emitted by the Fresnel lens is softer, it is often used ...
The application of analog sensors is very wide, which can be seen in industry, agriculture, national defense construction, or in the fields of daily life, education, scientific research, etc. However,...
Infrared thermopile sensors cannot work normally under a rapidly changing ambient temperature (if you suddenly approach a high-temperature heat source (fire) from a low-temperature heat source (ice), ...
Pyroelectric infrared sensor technology is one of the fastest-growing technologies in recent years. Infrared sensors have been widely used in many fields such as aerospace, astronomy, meteorology, ind...
What is the pyroelectric infrared sensor?The pyroelectric infrared sensor detects infrared rays emitted by people or certain animals and converts them into electrical signal output. It is a new type o...
Pyroelectric sensors can be used for passive infrared detection-that is, in common burglar alarms. This is the application of infrared pyroelectric sensors in the security field.How to choose a high-p...
1. Even if there is no epidemic, infrared thermometers will have stable rigid demand in the future.2. After the epidemic, there will be a big outbreak in the sensor Internet of things industry.The con...
The PIR alarm system is used to prevent problems before they occur. It is used to achieve a more thorough all-round management of the periphery and important jurisdictions in the building. The PIR ala...
The Fresnel Lens was invented by the French physicist Augustin Fresnel. He originally used this Lens design in 1822 to build a glass Fresnel Lens system-a lighthouse Lens. Fresnel Lens is an optical e...
The function of the Fresnel Lens is: 1. It can filter interference light. 2. The infrared signal can be amplified.When we do not use the Fresnel Lens, the detection radius of the pyroelectric infrared...
Any object higher than the absolute temperature will produce electromagnetic radiation-infrared. However, the wavelength and energy of the infrared radiated by objects of different temperatures are di...
Since infrared sensors with high sensitivity have realized non-contact temperature measurement, long-distance high temperature measurement and other functions, they have been widely used in various in...
With the development of modern science and technology, the development of infrared sensors will be broader. In the future development, the performance and sensitivity of infrared sensor will be greatl...
Photoresistor sensors are particularly sensitive to light, the stronger the light, the smaller the resistance value; the darker the light, the greater the resistance value. So this feature can be used...
