WeatherDuino Forum

I am trying to compile the latest AQM code but have run into problems. Using Arduino 1.8.13 and ESP8266 Boards Manager 2.7.4, all libraries removed except those provided in the download.. Selected Generic ESP8266 Module as the board(maybe this is wrong?)

I have a Z19B C02 sensor installed, and a HTU21D fitted. AQM is a 7003. Wifi enabled and credentials set. No display.

Here are the error messages. - It's got to be something simple I'm sure but can't see it. Huh

Hi,

When posting code, please use the code tags, otherwise its impossible to read the content.
Anyway I think you are compiling for a "Generic ESP8266 Module" instead of LOLIN(Wemos) D1 R2 & mini, thus the compiling error.

Thanks Caneira, yes the code errors are unreadable, I agree. Will give it a go and reply later.

Hi, that fixed the compile problems. Still having trouble getting readings from the TH sensor and nothing from the Dust sensor. Will keep at it, maybe ask more questions later. One thing, do I need to change any options in the the P2AT2560_RX_v8.3_b002 code to make it display dust sensor data? I can see the Dust sensor page but all zeros so far!

Hi Dave,

If you really are using P2AT2560_RX_v8.3_b002, then you need to upgrade to latest WeatherDuino Pro2 PLUS AT2560 RX v9.0_b003 .

If after upgrading, you still don't receive data from the AQMII, please post your Pro2 PLUS Config_Options.h file.

OK. Here is my progress since the last post. I am using all the latest software Pro2 PLUS RX v9.0_b003 and ASK/WiFi Air Quality Monitor v3.2_b003. I am getting good data from the AQM on the Pro2 Plus except for the AQM Temperature and Humidity which is always 9945 and 9980 on the Web page and I suspect this messes up the Dust Density calculations. The reason I say this is that I notice in your code if you select #define TH_SENSOR 0 then the AQM sends 25 deg C and 50% RH and then I get some meaningful Dust Density figures on the Pro2 Plus display. I have tried 2 different HTU21D sensors and each one gives the same readings. I have tested both of these on an Arduino with a test sketch and they both report readings similar to the Pro2plus sensor so believe they are OK.

I am using a CO2 sensor labelled as MH-Z19B and a PMS7003 dust sensor. I can hear the fan start a couple of minutes after resetting the ESP8266 Pro Mini and then see the webpage data updated. I have some SHT21 sensors on order and will try them when they turn up, but in the meantime any suggestions to problem solve would be very welcome.

The other thing I did was to use a multimeter and check the continuity of the HTU21D sensor socket on the PCB to the ESP8266 and find the SCL connects to D1 and the SDA connects to D2 which looks OK to me from the ESP datasheet.

Here is the webpage data :
{
"ID": "My-AQM",
"T": 9945,
"H": 9980,
"PM25": 0,
"PM100": 0,
"PM25AQI": 10,
"PM100AQI": 10,
"MAQI": 10,
"CO2": 408
}

Hi,

You are right about that. The data from the Temp / hum sensor are used on the calculations, so if data is wrong the results will be wrong too.

Please not that the SHT21 isn't supported. The best choice for the AQM II is the SHT31, 3,3V version.

Could it be that your HTU21D sensors are the 5V version and don't work reliably with 3.3V?
This ones are 5V version

[Image: s-l225.webp]

When you tested it on Arduino, you used the same library used by the AQM II? If yes, then they are on the expect I2C address, which is 0x40.

Another possibility... the pinout for the T/H sensor on the AQM II board is for the SHT31, most HTU21D modules, specially the 3.3V versions, have the SDA / SCL lines reversed, so they can't be fitted directly on the PCB. Check this too.

At moment I don't have any HTU21D to test. My best suggestion is to install an SHT31, they are far better than the HTU21D and more durable, specially under heavy moisture environments.

By the way, your Config_Options seems fine to me.

Hope I have helped.

My bad typing, I have bought SHT31 sensors supposedly 3.3V types. Will wait for delivery and test.

No I did not, used an Adafruit library I think. Will try the same library as in the upload. Will also check the address. Thanks

I used the Arduinos 3.3V supply for my test and also checked the SDA/SCL reversal as I have one like that that I bought without looking at the pinout.

At moment I don't have any HTU21D to test. My best suggestion is to install an SHT31, they are far better than the HTU21D and more durable, specially under heavy moisture environments.

Thanks for your suggestions, see my comments in italics above.

Regards Dave

Hi, I finally received my SHT31 sensors and pleased to report they work very well. I would recommend that the SHT31 sensors be used in the AQM as I have never been able to get the HTU21D sensors to work despite them testing OK in test sketches.

Thanks for all the suggestions. I have noticed another problem which I will raise in a new subject.
