The use of RS-485 and CAN interfaces for connecting sensors in climate control systems of greenhouse complexes

Abstract

Purpose of this article is to demonstrate the features of the use of existing connection interfaces for the functioning of climate control systems of agricultural complexes. The article contains the author's classification of the characteristics of the connection interfaces. The two most suitable interfaces are considered. The article compares RS-485 and CAN protocols. Key differences between CAN and RS-485 for use in agricultural complexes are shown. A test sample of a system containing 3 sensors was presented.
