RO purifier controller

The WT401R is a customized, IoT-enabled controller for RO purifiers. It runs the inlet valve, booster pump, UV lamp and flush valve, reads both TDS probes, the flow meter and the pressure and tank switches, shows the status on a 3-digit display, and reports every reading and fault to your server over 4G. The simulation below runs the same sequence with shortened timings.
