  Access over WiFi
Posted by: baz123 - 10-22-2016, 09:26 AM - Forum: vAir Monitor (CO2, Dust, Tempereature, etc..) - Replies (4)

Could it be possible to access the sensor via WiFi rather than plugging it in to another device all the time?

For instance, when first setting up, an API key could be generated which then allows the chrome app to communicate with the device via WiFi?  Alternatively a simple web interface directly on the device?

While playing with it, I keep wanting to change the interval!

  Setting up MQTT
Posted by: baz123 - 10-21-2016, 10:41 AM - Forum: vAir Monitor (CO2, Dust, Tempereature, etc..) - Replies (5)

I have mosquitto mqtt broker running on a Pi, communicating with other devices quite happily.  I cannot get the vair to publish to it.

Using the chrome app.

Host IP is set as is the port.  It accepts anonymous input so the user and pass are blank.

However, what exactly needs to go in the Client ID box, The topic box, and the larger box below?  A screenshot example would be good as https://github.com/vlast3k/vESPrino/wiki/Examples does not really help!


So the solution is to leave the topic box blank and use a single string in the 'messages' box such as

rx/21:{"CO2":"%CO2%"}

Edit:
Note if you use;
rx/21:{"CO2":%CO2%} you get a value at the other end rather than a string.

  Power?
Posted by: baz123 - 10-21-2016, 10:21 AM - Forum: vAir Monitor (CO2, Dust, Tempereature, etc..) - Replies (2)

This may seem a stupid question, but does the device need to be powered?  If so is there a minimum power required?  What is the power consumption?

Download the flashing tool for your OS from here
https://github.com/igrr/esptool-ck/releases/tag/0.4.9

and then execute something like (replace the comport)
esptool -vv -cd nodemcu -cb 256000 -cp "COM5" -cf latest.bin

  Unable to update NDIR vAir - CO2 Monitor FW
Posted by: Peter de Vries - 10-09-2016, 08:35 PM - Forum: vAir Monitor (CO2, Dust, Tempereature, etc..) - Replies (5)

Hi,

I am trying to update the firmware of my NDIR vAir - CO2 Monitor to the latest version.
However I get the following error:

vAir found on : COM3
received:vAir CO2 Monitor: v1.9.3
Visit 'vair-monitor.com' for configuration details

Tried it a couple of times.
Any idea what's going wrong?

Kind regards,

Peter

Information [SOLVED] CDM7160 - PPM Value Oscillation
Posted by: admin - 10-08-2016, 07:10 PM - Forum: vAir Monitor (CO2, Dust, Tempereature, etc..) - Replies (12)

Hi Guys,

It seems like the CDM7160 module is quite sensitive to noise from the power supply. I tested with several USB Chargers that i have and with all of them there is an oscillation of +/- 100 ppm in the output values. It also seems that some units are more affected from this than others.

On the other hand it works quite stable when powered from the Laptop or from a USB Battery.

I have contacted the manufacturer for some advice about this last week, but there is still no reply from them.

Unfortunately with the hobby-grage oscilloscope i have it is not possible to see further details, so next week i will go to a laboratory to analyze in detail what is the difference between the 5V from the Charger and the 5V from the Laptop. 

Most probably the solution will be some hardware filter that connects between the power supply and the device or between the sensors power supply and the base-board. Once i've figured it out and make it i will send it to all of you free of charge.

Regards, Vladimir

Question [SOLVED] Option to activate/deactivate the PM2005 particle sensor
Posted by: stephane - 10-05-2016, 01:22 PM - Forum: vAir Monitor (CO2, Dust, Tempereature, etc..) - Replies (25)

Hi Vladimir!

I have the CDM7160 + PM2005 sensor.
I would like to know my CO2 rate in my chamber during night but the PM2005 particle sensor is too noisy.
Is it possible to temporarily disable it ?

Thanks a lot for your help  Smile

  vThing CO2 Monitor Thingspeak update frequency setup
Posted by: vaanja - 10-01-2016, 02:59 PM - Forum: vAir Monitor (CO2, Dust, Tempereature, etc..) - Replies (6)

Hi Vladimir,
I'm just testing vThing - CO2 Monitor v1.15 (WIFI+NDIR). 
The sensor is on wifi, Thingspeak also working fine, but I would like to know if there is an option for adjusting data sending frequency.
Now it looks like sensor is sending update to Thingspeak on every CO2 level change (every 15 sec.)
There is no such option in Chrome config utility.
Many thanks in advance.
Kind regards,
Ivan

  CO2 value 65535.00
Posted by: Rutger - 09-30-2016, 03:51 PM - Forum: vAir Monitor (CO2, Dust, Tempereature, etc..) - Replies (10)

Today I received the CO2 sensor (standard ndir without extra sensors, CM1102).

In the Chrome app I added a custom HTTP, but they value that is visible in the log, is at start 550, and thereafter always 65535.00
Device is restarted 3 times and it's running now for 45 minutes.

During the setup I have seen some other values (I think) than 550 and 65535, like 5*** and 8****.
When I put a different placeholder in the url, the returned value is always 65535.00.

How can I fix this?
