Design of multi-channel temperature and humidity sensor acquiring system

Abstract

In this paper, the design of remote multi-point temperature and humidity control system consists of two parts of the master and slave, Responsible for the display and control of the host system. Responsible for the collection of temperature data and humidity data from the local system, Between the master and slave data transmission RS-485 communication interface chip, can be realized in a remote control room to monitor the scene of multiple monitoring points. © (2013) Trans Tech Publications, Switzerland.
