PM2.5 is a pollution sensor base with affordable price and high performance. Integrated with PMSA003 and SHT20, makes it possible to measure the ambient quality of air, temperature, and humility all at one device.

Much discussion and research have taken place within academic and government environmental organizations as to how accurate such sensors are and whether they have a place in the enforcing of environmental regulation, or even providing an indication of air quality trends to citizens.

With M5Stack product series, the system makes it much easier to deploy the measurement node all around the city and make it possible to build a complete ecosystem from regulation enforcement to citizen indication.

With regards to PMSA003, it is a digital universal particulate concentration sensor designed by using the principle of laser scattering method. It is capable of continuous acquisition and computing the number of suspended particles in per unit volume which is also the particulate concentration distribution. Then turn it into mass concentration and output through digital GPIO.

  • Precise measurement implemented by laser scattering method.
  • Digital output, standard UART comunication
  • 0 error alarm rate
  • real-time response
  • continuous acquisition
  • Minimum particle size resolution: 0.3 µm
  • Pattern structure design, 6-sides full dimension cover, high antijamming capability
  • Alternative in-outlet direction, wide application scale. users no need to redesign the air flue.
  • Tiny body, 12 mm. good for portable and wearable device

SHT20 is a Humidity and temperature sensor IC.

  • Fully calibrated
  • Digital output, I2C interface
  • Low power consumption
  • The excellent long term stability

    It worked as advertised, plug it to usb power, and thats it! You can easily Modify the program! Excellent product.

    The device has ceased operation

    but may be ESD problems from my seat have damaged it, would be great getting a M5stack replacement a a reduced price

    Nice, but too simple

    Work fast, sensors are good, but - turn it on and so?

    Missed multi-app functionality, no gas sensor, no logic based on air quality - maybe I want turn on air conditioner or trigger relay, no notifications....

    I mean - hardware is perfect, but out of box it useless. Just on and off.
    If you want sell ideal air quality kit solution, you need complete it with better sample software for wow-effect.

    I am really happy with the product and your service in general.

    5 stars.

    I own the PM2.5 and glad to have purchased the device

    I use it in my house and hotel stays to monitor air quality and the device is accurate. Now I can do my own development to set alarm points in code to wake me up should air quality become poor of hazardous. A effective device for the price!
