Monitoring Humidity & Temperature THD RS485 autonics using sharing data master slave arduino Mega MC

This video about how to share data from THD series Autonics to Arduino through RS-485. Data room temperature & humidity will be process in arduino mega and put data to MCU8266 via TX & RX. If connectivity is Okay , MCU8266 will get data from Arduino mega.
next video will upload data to database through wifi and Internet connection.
