Case study - Electronic design of a microcontroller based pump controller

Member News

SmartWater’s forensic spray system is an anti-intruder device that can be integrated with alarm systems to protect points of entry and high value areas.

Sorion were approached to design a product that will monitor the alarm output from a generic intruder alarm panel and to provide a timed discharge of SmartWater if the alarm triggers and the presence of an intruder is detected in the spray area.

The main objective was to replace SmartWater’s existing discrete solution with a microcontroller based pump controller that is easy to use and offers durability. Reducing the overall unit cost was also part of the brief.

The product development was undertaken in line with Sorion’s standard design process, consisting of the following discrete phases with defined deliverables: customer requirements capture, specification, hardware design, prototyping, software design, coding and validation testing.

The controller was designed to be simple and intuitive for the user while allowing for maximum flexibility with future enhancements in mind.

We are proud to have played a part in the project, helping SmartWater to quickly and cost effectively bring the new feature to market for their already successful SmartWater spray system.
