Waggle Sensor Plug-In for the Vaisala AQT530 Series Air Quality Transmitter
Depending on the configuration of the instrument, the AQT530 provides observations on meteorological conditions, including particulate matter (PM2.5, PM10) and gas species concentrations(NO, NO2, O3, CO).
The AQT530 utilzies an RS-485 serial connection to transmit data (RS-232 serial connection for instrument maintenance).
Therefore, to determine which port the instrument is plugged into, PySerial offers a handy toollist to list all serial ports currnetly in use.
python -m serial.tools.list_ports
The default serial settings for the RS-485 interface are:
- Baud Rate = 115200
- Data Bits = 8
- Parity = None
- Stop Bits = 1
Below is a sample of the ASCII formatted data string transmitted from the instrument. The specific variables included within the string and their location are displayed at the end.

Similar to the Vaisala WXT536 plugin a docker container will be setup via Makefile
make build
