Real Time Monitoring Device for Home Applications

This paper presents a device (data concentrator) capable of collecting data from different sensors connected by wire. Based on the RS485 communication protocol, it can package the data and send it further to cloud by means of GSM communication and FTP File Transfer Protocol. Such a device becomes very useful nowadays because it allows continuous monitoring of signaling in case of an emergency (fire, flood, security alarm). Special attention has been paid to the security of data transmission using a secure FTP channel.
