This driver is design to allow communication with the sensor via Modbus. This sensor provides instantaneous readings of the concentration of particulate matter. Readings are given for particles 2.5 microns or less and 10.0 microns or less. Using this information, the driver converts these reading into a US-EPA Air Quality Index value.

Name - The name is up to the user. Our suggestion is to choose a naming convention that makes the viewing the device list intuitive. Such as referring to the sensor and/or application. Keep the name short as it will be combined with the register name to create the default “Field” name (if added to “Fields”)

Active Check box - Check this box and “Save changes” to run the driver. The driver program can be suspended by unchecking the box and clicking on “Save changes”.

User Notes - This space can be used to store information specific to the device and your application, such as: location, wiring, scaling, etc.

eze System Notes - In this space we provide: wiring instructions, product image, product details.

Modbus address - Enter Device I.D. (Modbus address). This address must be unique on the bus.

Driver info - Typically this is the name from the program file

Driver updated/version - Date loaded or updated and the version of the driver

Battery & Signal - Signal indicates the progress through the script. If driver fails to operate, signal number indicates progress

Driver status - Color and text of status bubbles give a quick visual reference of Communication, Operation, and Application

Communication - Com count indicates number of successful and unsuccessful data packets received

1. PM2.5 - Concentration of 2.5 micron particulate matter. Measurement in micrograms per meter squared.
2. PM10 - Concentration of 10 micron particulate matter. Measurement in micrograms per meter squared.
3. AQI US-EPA - Air quality stated as the US EPA air quality index (AQI)
