Each subsystem in a Particles Plus instrument has its own local processing. The photo-amplifier, pump controller, temperature/humidity sensor, battery pack, and other key functions operate independently and in parallel within the system. The various subsystems process data locally and pass data back to the main controllers for display or logging, providing a significant increase in performance for the system and allowing enhanced diagnostics and troubleshooting.
Particles Plus’ architecture allows the swapping of subsystems to create different instruments with different feature sets without requiring extensive firmware or hardware changes to the system itself. For example, a user can replace a standard temperature/humidity sensor with a higher accuracy version of this sensor and the instrument will detect the change and adjust the displays accordingly to reflect the new sensor. Or, the temperature humidity sensor could be replaced with a completely different sensor type (air velocity, differential pressure, CO, CO2, etc.) and the instrument would detect the change and reconfigure itself to display the appropriate sensor data. The user can also swap batteries, substituting the standard sized battery for a larger capacity model and the instrument would detect the change and adjust the charging and management accordingly.
