Case Study - Pool Chlorinator


Business Case

We developed a low-cost pool chlorinator with difference.  Many pool  chlorinators use 2 plates and an electrical current to produce chlorine.  A common problem is that the chlorinator requires regular maintenance.  One of the electrodes requires cleaning before the white calcium build-up becomes too thick.  This chlorinator has a unique feature.  It does not require this maintenance.  It a great product differentiator in a competitive market.

The product

The chlorinator was based around a low-cost PIC microprocessor.

The display is a 20 characters by 4 lines LCD.  4 push buttons are used to interact with the display and setup the chlorinator.  The bottom line of the display was used to display 'soft keys' - like on a mobile phone.  The chlorinator can be programmed to run for certain hours of the day on a 24 hour or 7 day timer.  The current to the chlorinator can be adjusted using a dial.

The project included a product proposal, electronics design, schematic entry, PCB layout, [embedded] software for the PIC microprocessor and prototype testing.  The customer supplied the product housing and arranged the manufacturing.
