Product Description

This product supports 5V power supply voltage, output signal TTL

Is 5V, higher than this voltage, the product will burn out,

Please remember!

This product uses the principle of laser scattering and can obtain the concentration of suspended particles in the air of 0.3 to 10 microns.

Remarks: The pitch of the interface is 2.54, and the 90-degree pin interface is used without special instructions;

Product specification

Product size: L*W*H=71*70*23mm

Protocol :

Serial communication protocol: 9600 8N1. (Rate 9600, data bit 8, no parity bit, stop bit 1)

Serial port reporting communication cycle: 1+0.5 seconds

Data frame (10 bytes): message header + instruction number + data (6 bytes) + checksum + message tail

Byte number name remarks

0 packet header AA

1 Instruction number C0

2 Data 1 PM2.5 low byte

3 Data 2 PM2.5 high byte

4 Data 3 PM10 low byte

5 Data 4 PM10 high byte

6 Data 5 0 (reserved)

7 Data 6 0 (reserved)

8 Checksum Checksum

9 Trailer AB

Checksum: the sum of bytes from data 1 to data 6.

PM2.5 data content: PM2.5(ug/m3) = ((PM2.5 high byte*256) + PM2.5 low word

Section)/10

PM10 data content: PM10(ug/m3) = ((PM10 high byte*256) + PM10 low byte)/10

1. First install the USB to TTL driver software;

2. USB to TTL serial cable, connect PM2.5 sensor, plug in computer;

3. After power on, open the serial port debugging assistant software, select the serial port used by the USB to TTL serial line, and use the baud rate of 9600.

    I did a sample code to test out the accuracy, and it performed very well. However, now I am trying to implement this into my own air quality control program in my house. I want to trigger my air purifiers at a certain air quality. A little more involved but it will be so worth it when I figure it out! LOL!

    Amazon Vine Customer Review of Free Product( What's this? )
    I think that the DEVMO PM Sensor (SDS011) is similar to the PM sensor in my air filters/cleaners, except the SDS011 has a fan. I wasn't able to find docs, as such, but I used the sensor with an ESP32 with no issues. I used serial comms, and the settings on the product listing page worked as expected. I'm using my sensor to measure particulates in my workshop area. If the concentration gets high, and my dust removal system isn't on, it turns it on (via HomeSeer). The sensor isn't cheap, but the DEVMO seems to be on the lower end of the price scale. Recommended

    Very sensitive, 1 second update time. I got a TemTop too, but it wasn't accurate. This is much more reliable and passed a high dust test. It's packaged really well too. Has a quality feel to it, even being an exposed raw component. There's actual PubMed journals on this Nova Sensor SDS011 that show "93% to 97% R2 values" compared to the best particle sensor known to man. For indoor use, outdoor isn't as good. Google the journal article.

    There's no software or docs included. But I found "DustSensorViewer" or "DustViewerSharp" on Galch's GitHub for an extremely easy Plug N Play software. Screenshot attached. I installed it. Plugged in the USB, and it was live streaming data immediately.

    Really like this tool. Especially because it is so hard to find a cheap but reliable particle counter for both PM2.5 and PM10. I find both values important. Highly recommend so far.

    5.0 out of 5 stars Easy to implement PM2.5 and PM10 sensor.
    Reviewed in Canada on May 9, 2024
    Amazon Vine Customer Review of Free Product( What's this? )
    The DEVMO PM Sensor SDS011 is a fun to implement PM2.5 and PM10 sensor.

    It comes with the SDS011 sensor board and a USB to serial interface board. You can use the USB to serial interface board or just connect it directly to a microcontroller. I chose to connect the sensor to a microcontroller rather than using the USB board.

    The SDS011 has a small fan to intake air into the sensor unit. The air is passed between a laser diode and a photo diode which counts the particulate. The sensor returns a digital count of the PM2.5 particulate and the PM10 particulate.

    I found some libraries for the SDS011, so it was very easy to get it working. I let it take a baseline for a bit and then put it over a candle. When the candle has visible wax vapor, I saw a big spike in both the PM2.5 and PM10 counts. I included a picture of a plot of the PM2.5 (red) and the PM10 (blue).

    I plan on integrating a small display with this and having a portable air quality meter. It is a pretty cool little sensor.
