Nowadays thermopile reactor sensors and pyroelectric sensors commonly used in daily life. However, are they sharing the same scientific principles? What are the differences between them?Knowledge of T...
The optical resistance sensor of photoelectric switch refers to the sensor made of the piezoresistive effect of monocrystalline silicon material and integrated circuit technology.The photoresist effec...
Fog, rain and dust rather than night and day will affect the accuracy of temperature measurement of infrared thermopile sensor. The reason is that the infrared light will be attenuated to some extent ...
Infrared thermopile sensor combined with Fresnel lens can greatly enhance its detection range. In general, the maximum distance of detecting the surface temperature of human body can reach 6-10m under...
Linear light sensor is also called phototransistor. The integrated chip is very sensitive to light changes. Therefore, it is usually used to detect the current ambient light level and convert the ligh...
Digital PIR sensor is a new type of electronic weighing sensor developed on the basis of traditional resistance strain sensor, combined with modern microelectronics technology and microcomputer techno...
Thermopile is a kind of thermoluminescence infrared sensor, which is a device composed of thermocouple. It has been widely used as a temperature detection device in ear thermometer, radiation thermome...
In the laser infrared alarm, there is a photoresistor. What is it? How does a photoresistor work?Photoresistor, also known as photoconductor, is made of special materials. Photoresistor is a special r...
What is a thermopile sensor? To put it simply, the thermocouples are usually connected in series, sometimes it will be in parallel that is thermopile. Thermopiles can't measure the absolute temper...
Avoid false alarms1. Do not place heat generating objects within the detection range of the thermopile sensor, such as heaters, water heaters, televisions, computers, refrigerators and other electrica...
In general, the Fresnel lens are cut in spherical surface shape in order to minimize the optical aberration of the image during imaging. The lens can better calibrate the ideal point light source into...
At present, the supply of thermopile sensors has been in short supply due to the sudden epidemic situation. Due to the shortage of stocks in the market, the price has risen again and again, which has ...
(1) Brief introduction of thermopile sensorThermopile is a kind of component that can mutually transform temperature difference and electric energy. It is composed of two or more thermocouples in seri...
Thermopile sensor is often used in non-contact infrared temperature measurement, because any object higher than absolute zero can emit infrared, and the energy radiated by the object increases with th...
As a non-contact and fast human body temperature measuring equipment, infrared temperature measuring equipment has played an important role in this pandemic. Under the huge market gap, the capacity of...
