PM1, PM2.5, PM10 particulate sensor - Quick guide
Introduction
1
PRPMA3100 is a sensor for simultaneous detection of PM1, PM2.5, PM10 particulate matter. The determination of particulate concentration is based on
the light scatter measurement method.

3 Installation
For the installation, consider the following:
- Install the sensor far away from pollution sources that are very close and have insufficient air flow (such as chimneys, air conditioners, etc.) that may
disrupt your readings.
- Install the sensor between 3 and 4 meters high.
- For optimal sensor performance, it is recommended to mount the device in a location that is not directly exposed to sunlight or receives as little
sunlight as possible.
- To ensure proper operation, the sensor must be installed with the air inlet of the sensor facing downward.
1. Install the mounting bracket on pole or wall. In the
first case, fix it to the pole using the stainless-steel
hose clamp.
In the second case, attach the mounting bracket to
the wall using two screws as shown in the figure.
2. Click onto the bracket the sensor.
4. Open the cover be-
ing careful not to
tear the cable that
connects it to the
internal board.
4 Communicating with the PRPMA3100
Real-time data access occurs through Modbus RTU protocol over RS-485 communication port.
4.1 Using with LSI LASTEM data logger
If the sensor is used with Alpha-Log, refer to DISACC240039 for the connection.
To configure Alpha-Log to read PRPMA3100 sensor data, use the 3DOM software. Proceed as follows:
➢ Open the configuration in use in the data logger.
➢ Add the sensor by selecting the model PRPMA3100 from the 3DOM sensor library.
➢ Check the acquisition parameters (input, rate, etc.).
➢ Save the configuration and send it to the data logger.
For more information about the configuration, please refer to the manual of the data logger and the 3DOM online guide.
