Sockets are configured to listen to a data port or to connect and then transmit to a remote one. Winsock is used for network communications via the TCP/IP protocol. Internet communications is relied on socket programming. They use VB MSComm control in order to communicate with the microcontroller. Both the client and the server side programs are coded in VB programming language. Microcontroller transfers the sensors data to the server via serial port. The required hardware include a microcontroller and accompanying electronic circuitry, a server computer, serial port, temperature and relative humidity sensors and two actuators. The various stages in the design and implementation of system for monitoring temperature and relative humidity and controlling HCS environment conditions are presented and discussed. In this article, a distributed architecture that allows remote control and monitoring of horticultural cool storage (HCS) is presented.
