HN911红外探测器,属热释电型,也称红外探头。它是将移动发热体发射出的微弱红外线能量,转换为电信号的器件。HN911红外探测器灵敏度高,探测范围广,很适合于家庭电子爱好者用来自制各种探测、报警电子装置。这种红外探测器在结构上采用了微型化,在设计上突出改善了信号处理电路和抗干扰电路。因此其抗干扰,能力强。它还具有功耗小、耐低温等特点,基本上能满足我国不同地区的要求。HN911系列模块有三种型号,即HN911T(通用型)、HN911L(微功耗
HN911 infrared detector, a pyroelectric type, also known as infrared probe. It is a device that converts the weak infrared energy emitted by mobile heating elements into electrical signals. HN911 infrared detector high sensitivity, wide detection range, it is suitable for home electronics enthusiasts used to make a variety of detection, alarm electronics. This type of infrared detector has been miniaturized in structure, and has been designed to improve the signal processing circuit and the anti-interference circuit. Therefore, its anti-interference, ability. It also has a small power consumption, low temperature and other characteristics, basically to meet the requirements of different regions of our country. HN911 series modules have three models, namely HN911T (Universal), HN911L (micro-power
