iROS complies with AS2809 for use on dangerous goods tankers. The concept was conceived in mid 2002 from dangerous goods industry operators demanding a more accurate, dependable and reliable roll over switch device for shutting down a vehicle that has been involved in a "rollover", whilst at the same time offering increased safety to the vehicle and driver with less chance of an accidental shutdown.

iROS has been continually developed, tested, and refined since 2002 by technical staff working in the heavy vehicle dangerous goods industry, as well as consultant electronics engineers with expertise in automotive, military and aerospace applications.

At the heart of the iROS, is a programmable microprocessor. This processor allows the iROS to be "programmed", expanding the functionality of the unit to much more than that of just a dumb switch. iROS uses a dual-axis accelerometer (angle vs. g-force sensing device) originally designed as part of a missile guidance system. The data from this sensor is then processed by the onboard microprocessor to determine if a rollover has occurred, and whether the unit should switch the output. The unit will only switch if all of the criteria (that is, angle and motion) are met and held for a set period.

The iROS boasts many standard features that competitors just simply cannot offer. These include a manual system test function, automatic test functions, warning light outputs and the logging of operating hours and isolations.
