I am not getting anymore values to thingspeak or my MQTT server. Its a bit weird. LED light is Lila. MQTT always shows me a client got connected the same second I press the Test button and directly after that a client disconected but no message is send, also my other devices work fine. Blynk and thingspeak are the same. In Blynk it appears as Online but yeah no values at all.

  PM25 and PM10: bad report on domoticz over Wifi
Posted by: nmaster - 01-06-2017, 12:56 PM - Forum: vAir Monitor (CO2, Dust, Tempereature, etc..) - Replies (3)

Hi,

I just wanted to add PM25 and PM10 on my domoticz using wifi.

It actually send the CO2 value for both sensors.
I put correct IDXs of my dummy sensors.

I have right values on the config tool.

I'm using vESPrino v1.16 build20161217 firmware.

Other sensors are OK, I use it for weeks now.

My CO2 monitor has just stopped sending data via MQTT.  I have not done anything.  LED is purple.  Tried connecting it to th Chrome app and all seems fine. Tried an otah command but still nothing.

  Not sending data to Emoncms
Posted by: mattG - 12-21-2016, 05:25 PM - Forum: vAir Monitor (CO2, Dust, Tempereature, etc..) - Replies (3)

We have been trying to get a new vAir Monitor to send its readings to a account on the Emoncms.org site. Apart from a couple of initial readings after we have setup key values for each senor, we have not received any data. The vThings Configuration Utility does show it getting readings, and if I send the call_url, with the line found under the http section of the utility, replacing the %TEMP% with fixed value it will update Emoncms.org account.
Can you advise if we have missed something in setup it?

Thanks

  Change wifi
Posted by: Alex Keith - 12-18-2016, 07:54 PM - Forum: vAir Monitor (CO2, Dust, Tempereature, etc..) - Replies (7)

Recently received a new router with new username & password. When i go into my c02 monitor to change the settings with the configuration tool, i cannot change the details. Looks as though it might have updated when I click set wifi, but when plugged back into PC the old details are still in the memory.

  [TGS4161] Improving the CO2 Accuracy
Posted by: admin - 12-16-2016, 03:42 AM - Forum: vAir Monitor (CO2, Dust, Tempereature, etc..) - No Replies

This post will cover tips and tricks required to make the TGS4161 work more consistently. This was the original CO2 Monitor that i had made (with 6 LEDs and optionally Display and WiFi)

The TGS4161 is an electrochemical sensor that is said to deliver +/- 20% accuracy of CO2 Concentration.

While this may be true, time has shown that there are several important things to keep in mind, due to the fact that it is electrochemical and some things change over time.

1. If the sensor is powered on and disconnected only for short (<5-10 minute) periods of time it works quite well.
2. Once the sensor is disconnected for a longer period of time - two things happen

   2.1. It starts thinking CO2 is more than it actually is (this may be even with more than 3000 ppm). To fix this a couple of things can be done
         - (automatic) ensure latest FW is used (see below on upgrading to latest fw). The earlier firmwares did autocalibration each 10 days, the new one does it each 3 days
         - (manual) via the vThings Configuration Utility (see below) press the button in Settings -> Reset Calibration. Then the calibration cycle will start again and it will adjust to the lowest CO2 level faced (if it is not too cold outside <10 degrees C, you can put it there for 15 minutes)

  2.2. It starts thinking CO2 is less than it is. E.g. it is 2000 ppm in the room but it shows 1000
         - calibrating the top level cannot be done automatically. This is why the solution is to issue a special command from the config tool, put the sensor in a plastic bag, exhale your breath in it. And leave it like this for 10 minutes. The sensor measures up to 15,000 ppm, and we exhale 50k+, so this will do it. This is not yet part of the firmware. Please subscribe to this topic to get update about it.

Once those two procedures are done - the sensor will again show reliable data, until the next time it is turned off. I believe at some point of time after a a number of restarts, this will settle, but i haven't done measurements for this

Checking firmware version
Follow the steps as described here http://vair-monitor.com/device-types/. Once the config tool starts it will show the version in the first line in the output.

Latest version is: 1.11

Updating to latest firmware version

  1. Download the XLoader tool from here https://github.com/vlast3k/simple-co2-monitor-fw/blob/master/files/XLoader.zip

  2. Download the latest firmware from here: https://github.com/vlast3k/simple-co2-monitor-fw/tree/master/fw, and unzip it. Make sure to download the correct file. _tgs - this is for the original and cheaper sensor with the less accurate sensor (TGS4161), _ndir - this is for the more accurate IR-based sensor. Flashing the wrong one will not brick the device - it will simply display wrong values

  3. Configure the tool like this (by adding the correct port):

  [SOLVED] Fried my monitor?
Posted by: freakstar - 12-15-2016, 05:37 PM - Forum: vAir Monitor (CO2, Dust, Tempereature, etc..) - Replies (16)

Connected the monitor to an USB power supply with 5.2 V, 2.1 A output. The LED lit up white (very bright) and now the monitor isn't sending data or recognized anymore on my computer. 

Did I fry it?

  Integration with Blynk.cc
Posted by: admin - 12-15-2016, 05:36 AM - Forum: vAir Monitor (CO2, Dust, Tempereature, etc..) - Replies (4)

For those of you that would like to use some kind of mobile integration with the devices - it is finally there!
Although not developed for me, by using Blynk you can now create a custom mobile dashboard. Simple ones would be for free. If you need more gadgets it would cost you 1-4 eur :Smile (to the Blynk service developers)

i've published more details here: http://vair-monitor.com/2016/12/15/mobil...ith-blynk/

  Solar Power

Hi Guys,

Now that the major issues with the design are more or less mitigated, i started thinking on what would be the next level.
Up to now i've consistently avoided using batteries, as this adds another level of complexity. So i decided to pay some skilled freelancer to do the schematic design this time. The question is what would be the requirements for a battery powered device. What i am thinking of is:

- Power consumption of a wireless device is in the range of 2-8 ma/h (send each 10 min, vs each 2 min), mostly consumed by the Wifi module while sending data - for 3-4 seconds @ 250ma/h.
- The CO2 sensor consumes ~ 8ma/h while active, and it takes ~60 seconds to get stable results, so if it is switche on each 5 minutes for 1 minute, this would reduce it to 1-2 ma/h
- Temperature sensor does not consume anything

So this totals to about 50-100 mah per day

Standard AA cells have 2000 MA, C cells have 5000, D cells have 10000
14500 lipos have ~1000 ma
18650 can have up to 5000 ma

So now in any case the device has a limited lifetime before the batteries are dead.

This is why i started wondering - what if i add also some 5x5cm solar panel. If it can deliver up to 10-20ma per hour during the day (even if not every day) this would be enough to cover the daily consumption.

Has any of you thought about this?
I saw a similar comment of Rene Arts in one forum. But maybe others have also thought about this

Regards, Vladimir

Question New Configuration Tool and Firmware - testers appreciated
Posted by: admin - 12-05-2016, 05:17 AM - Forum: vAir Monitor (CO2, Dust, Tempereature, etc..) - Replies (4)

Hi Guys,

I've spent almost each early morning (4-7 am) for the last two months to do some improvements to the firmware and configuration tool.

I've just updated the Chrome App, so it should automatically update in your browsers:
http://vair-monitor.com/2016/12/05/vthin...tool-v8-0/
here are some details.

The firmware also contains lots of changes. Primary to make it work more stable and better. And also it had reached my programming skill limits to maintain it so i had to refactor some stuff to make it simple.

You can update to it with "otah" command.

It would be great if i could get some feedback from you about this update. I would like to push this latest version automatically to all devices. I've been testing it in the last week, but i prefer to have some slower ramp up before i do it.

Thanks in advance, Vladimir
