摘　　要：甲醛是一种常见的装修型化学性室内空气污染物,是制造油漆、塑料、橡胶、染料等的原料,严重的危害着人们的健康。本设计了一个基于甲醛传感器的智能控制系统,该系统以AT89C51单片机为核心处理器。AT89C51是性价比高的8位单片机,具有丰富的外围电路。本设计中采用串行通信方式,利用少量的I/0接口,采用TLC2543串行A/D转换芯片和CH2O/S-10型甲醛传感器,简化了系统的配置且降低了设计成本,可广泛用于甲醛浓度的监测和控制。Formaldehyde is a kind of popular indoor air pollutant an important chemical raw materials and organic solvents, manufacturing paint, plastics, rubber, dyes and other raw materials. In addition, formaldehyde seriously endangers people＆#39;s health. This paper design a intelligent control system which is based on formaldehyde sensor and AT89c51. AT89c51 are 8-bit single-chip, cost-effective, rich peripheral circuits, the design uses a serial communication means, using a small amount of I/o interface, using Tlc2543 serial A/d conversion chips and cH20/s-10 serial formaldehyde sensor simplify the system conifguration and to reduce design cost, it can be widely used in formaldehyde concentration monitoring and control for faimilies.
