Infrared beam and reflection: differences and characteristics In today's field of science and technology, infrared tube technology is widely used in various equipment and systems. However, many people may not be fully aware of the concepts and

The working principle of PIR sensors is based on the principle that a human body or other warm object radiates heat in the form of infrared radiation. When a human body or other warm object enters the sensing range of the PIR sensor, the sensor detects in

隨著科技的不斷發(fā)展，環(huán)境光傳感器在汽車(chē)行業(yè)的應(yīng)用越來(lái)越廣泛。 一、環(huán)境光傳感器的原理與功能 環(huán)境光傳感器是一種檢測(cè)周?chē)h(huán)境光照強(qiáng)度的裝置。它通過(guò)測(cè)量光的強(qiáng)度，可以判斷出汽車(chē)所處的環(huán)境光照情況，從而對(duì)汽車(chē)的照明系統(tǒng)進(jìn)行自動(dòng)調(diào)節(jié)。 二、環(huán)境光傳感器在汽車(chē)行業(yè)的應(yīng)用 1.自動(dòng)調(diào)節(jié)照明系統(tǒng) 環(huán)境光……

在當(dāng)今的科技領(lǐng)域，傳感器發(fā)揮著重要的作用。其中，亮度傳感器和環(huán)境光傳感器在我們的日常生活和各種設(shè)備中尤為常見(jiàn)。那么，這兩者之間有什么區(qū)別呢？本文將對(duì)此進(jìn)行深入探討，幫助你更好地理解這兩種傳感器。 一、亮度傳感器 功能與工作原理 亮度傳感器主要用于測(cè)量物體發(fā)出的光線的強(qiáng)……

在紅外通信領(lǐng)域，到底是紅外二極管還是紅外三極管更適合接收端？在深入探討這個(gè)問(wèn)題之前，鑫永誠(chéng)光電帶大家理解這兩種組件的基本工作原理和特性。 紅外二極管，也稱(chēng)為紅外接收二極管，是一種專(zhuān)門(mén)設(shè)計(jì)用來(lái)接收紅外信號(hào)的半導(dǎo)體設(shè)備。其主要工作原理是當(dāng)加正向電壓時(shí)，即二極管兩端加上正向電壓時(shí)，即P區(qū)接正N區(qū)接負(fù)，在外加電場(chǎng)作用下，……
