Pinout

Board Pins Raspberry Pi
5V 5V
GND GND
PMS RX GPIO 14
PMS TX GPIO 15
PMS SET GPIO 27
PMS RESET GPIO 17
OLED SDA GPIO 2
OLED SCL GPIO 3

Installation

Python

Required Hardware
  • Raspberry Pi x 1
  • Air Monitoring HAT x 1
Enable I2C and Serial Interface
  • Open a terminal and run the following commands to enable I2C：
sudo raspi-config

Choose Interfacing Options -> I2C ->yes

  • Again run below command to enable Serial
sudo raspi-config

Choose Interfacing Options -> Serial -> No -> Yes

  • You can also enable Serial and I2C using Graphical method, Open Menu by clicking on Raspberry Pi icon >> Preferences >> Raspberry Pi Configurations >> Interfaces , and select below option.

  • Now reboot your pi by running the below command :
sudo reboot
Board Test
  • Clone Github repository of Air monitoring HAT by running below command and enter its directory.
git clone https://github.com/sbcshop/Air-Monitoring-HAT.git
cd Air-Monitoring-HAT
  • Now run GUI of Air monitoring HAT by running the below command on terminal.
python3 Air_Monitoring_GUI.py
  • Select COM port from above GUI ("/dev/ttyS0" in case of default connection), and click on the start button to start Real-Time data from the sensor.
  • You can also use these two examples and modify them easily :
    • display_on_oled_example.py :- To print the sensor data on Oled Display.
    • read_example.py : To print the sensor data on Python shell or Terminal.

API Usage

Guide to print data on python shell or terminal

  • Import required dependancy by adding below lines.
from pms_a003 import Sensor
  • Now create a sensor class object.
air_mon = Sensor()
  • Now initialize serial connection.
air_mon.connect_hat(port="/dev/ttyS0", baudrate=9600)
  • Read and print sensor data on python shell / terminal.
air_mon = Sensor()
  • Read and print sensor data on python shell/terminal
values = air_mon.read()
print("PMS 1 value is {}".format(values.pm10_cf1))
print("PMS 2.5 value is {}".format(values.pm25_cf1))
print("PMS 10 value is {}".format(values.pm100_cf1))
  • To disconnect or drop serial connection, use the below function
air_mon.disconnect_hat()

Guide to print data on Oled Display

  • Import required dependency by adding below lines.
from pms_a003 import Sensor
from oled_091 import SSD1306
from time import sleep
  • Now create class object for oled and sensor
oled_display = SSD1306()
air_mon = Sensor()
  • Now initialize serial connection
air_mon.connect_hat(port="/dev/ttyS0", baudrate=9600)
  • Read and print sensor data on Oled Display
values = air_mon.read()
oled_display.PrintText("PM1.0= {:2d}".format(values.pm10_cf1),
                               cords=(2, 2), FontSize=10)
oled_display.PrintText("PM2.5= {:2d}".format(values.pm25_cf1),
                               cords=(65, 2), FontSize=10)
oled_display.PrintText("PM10= {:2d}".format(values.pm100_cf1),
                               cords=(25, 20), FontSize=13)
oled_display.ShowImage()
sleep(1)
