The graphs below show the key water parameters in the tank, updated every 15 minutes.  Ensure that you refresh this page to get updated graphs. Any gaps in the graphs represent internet connection downtime or equipment downtime.

NOTE: at the moment the absolute levels for salinity and pH are way off, we think because of using old calibration solution.

The data is collected using an IKS Aquastar kit. We have a base unit to which you can connect up to 8 probes; we have temperature, pH, salinity and redox probes.  All have been reliable apart from the salinity probe which, because of the way we've positioned it, tends to collect air bubbles.  The base unit stores up to 2000 measurements at a programmable interval and also makes readings available every few seconds through an RS232 port. We've attached an RS232 to Wifi converter to this and then collect the readings through a virtual COM port on a PC elsewhere in the house. There we process them and FTP them to our website every 15 minutes where a PHP script formats them for display.

The IKS Aquastar base unit can also be used to control equipment, including day-night intervals etc, though we've not got into that yet.
