摘要:
设计一种增益自调节空气负离子计数器。该装置以STC15F2K16S2为控制器,AD采样器,以CD4052为电子开关,MAX7426为滤波器,通过增益切换实现负离子计数器量程自动调节。试验结果能反映植物负离子机开机时不同距离的负离子浓度,表明该设计抗干扰能力强,结构简单,方便测量,满足对不同浓度的空气负离子测量要求。
Abstract:
An air negative ion counter with gain self-adjustment was designed. The device comprises a STC15F2K16S2 controller, a sampler AD with an electronic switch CD4052 and a Max7426 switch-capacitor filter, which can automatically adjust the range of negative air ion counter via gain switching. The results show that the design is of strong anti-interference, and is convenient to measure negative air ions with simple structure. In addition, it can detect the concentration of negative air ions in different distances, satisfying the requirements of measuring negative air ion concentration.
