Design of the Temperature and Humidity Automatically Detecting System Based on AT89S52/55

Abstract:

The temperature and humidity automatically detecting system based on AT89S52/55 single-chip is designed in this paper, which can realize temperature and humidity itinerant measurement of 32 points. This detecting system is made up of the single-chip system, sensor, multipath switch and signal processing, A/D conversion subsystem etc, multipath signal selection can be completed by CD4051 with CD4052, the circuit is simple and dependable.
