the Circuit design of Formaldehyde pollution detection and processing system based on At89C51
lIxin-mei
Abstract：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'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.
