Need to log three values from ethernet connected device - Example for code is [url removed, login to view]
Also want to display graph of last 24 hours of the three values via HTTP
Devices are locally connected (one or more devices, usually just one)
Variables, refresh every 30-sec:
http://192.168.1.5/setget?%sen-1 (temperature, Celsius - need option to display and log in Fahrenheit)
http://192.168.1.5/setget?%sen-2 (RH%, relative humidity)
http://192.168.1.5/setget?%sen-3 (CO2 level, ppm)
Log data every 15 minutes to MySQL database.
This data will be used in indoor and greenhouse horticulture.
Need ability to easily create graphs and logs of an entire growing cycle
If a log can be created that can be accessed in CSV format, that will work well. Also want the data to be available to control various relays to provide control of the environment at a later time. Might want to access the real time data using a PLC via ethernet or other communication (RS232, RS 485?).
My immediate needs are to log and display the data and send email message if a value goes out of pre-set range (user defined).
Thanks! Dan Weddle / DX Hydro
