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.
2022-08-15Upgraded product with digital high sensitivity and multiple installation methods
This Infrared Motion Sensor is an upgraded product with digital high sensitivity and multiple installation methods. The working voltage range is 100-277V. Working frequency 50/60Hz.
2022-08-02What are the application cases of sensors in our life
With the development of The Times, intelligent technology has gone deep into our life, as big as the control of the whole building system, as small as a small access card reflects the era of intelligence. Hidden within these systems and tools are important components, sensors. A device or device that senses measured quantities and converts them into useful signals according to certain rules. Did you know that sensors are everywhere in our lives?
2022-07-26Functions of Infrared Induction Lamp and Precautions
When installing, please install the smart lamp in a place where people often move (ceiling or wall) to improve its sensitivity and working range. Do not install on a damp ceiling or wall. Disconnect the power supply first when cleaning
