Citizen’s Oil and Gas Monitor:

I see this as a "citizen" monitoring system. The concept is to monitor Air Particles, VOCs (Volatile Organic Compounds), and Sound levels in real-time. Five second data is averaged each minute. Sound is maximum for the minute and updated each minute. The intent is to keep the driller and producer honest in their commitment to low air particles, noise, and VOCs. Each system can be built for less than $200 and uses their router and internet connection. The data is sent to a server each minute and displayed along with other monitors on Google Maps. The markers shown on the maps display I (information), W (warning), or A (alarm) and are updated each minute. When clicked they display the last known data for the System Inputs shown below. For more information on the map, click Main on the Contents (left pane) and look for the "Map" description in the right frame. A plot button displays the last 24 hours for the monitor selected.

Weasel Words -- This is not associated with the City and County of Broomfield, Extraction Oil and Gas, or Crestone Peak Resources. I asked if I could use CSU to calibrate the meters and was told: "CSU and Ajax need to remain focused on the collection of data, testing, and reporting aspects of the air monitoring project and will not be able to expend resources associated with the citizen's oil and gas monitor. Use of the data and/or any maintenance or calibration task performance are not in the scope of the contract that CCOB issued to Ajax/CSU." So... use or read these monitors with the understanding that they are not calibrated. Personally, I think they are close, updated on the web each minute, and definately track the events. I fully intend to persue calibration. I know these digital sensors are much more stable and accurate than their analog counterparts in the past. For now, I think we can compare the numbers with the reports that come out of Broomfield. If you experience adverse health effects, blame the oil and gas drilling, or the State of Colorado and the City and County of Broomfield for their inadequate setback distance. Please don't blame these monitors. Thank you and Peace.

I don't attempt to read BTEX components. (Benzene, Toluene, EthylBenzene, and Xylenes) They will need to be monitored by Broomfield using canisters near the well areas and analyzed using gas chromatography–mass spectrometry after the fact. But BTEX is proportional to VOCs. Broomfield should be notified and one should stay indoors if VOCs rise.

Please see: or click Map under Contents on the left. (A work in progress.) Only a few markers are operable. The rest marked with an "X" are "fake news" and it is in development so it could / will be missing data depending on when you access it. Click on the marker to see the above values. Click on Plot button to see the last 24 hours.


I have a seller and links to each item under Checklist (below). You don't have to choose the seller. The item should match or be compatble.

Not part of the system but needed to make it work:

Tools: (or a handy relative)

Software: Some perspective ... The software consists of:

Help: (Have specific questions when you come here else you could spend a day.)

This table is located here so when you run across logins and passwords later, it will give you some perspective. It is not here to intimidate you. We will work through these one at a time.

Status:This is a project in progress.

“BUILD” (below) can be at the persons home where the monitor will run, or at a business, or anywhere there is a computer and Internet connection. The Builder will have their own Login, Password, and Location.

“INSTALL” has to be at the place the monitor is going to run.
When you get stuck with my description of connecting to the router because yours is different, Please look under "INSTALL" at the bottom. Not that I will have the answer there, but that is where I will add different versions of routers. The Install repeats items already done in Build that change the Login, Password, and Location to those of the final Install site. If the Builder is the Installer those items are already done with the exception of Install on the house.

BUILD: Total 17 hours

1 hour -- Order Hardware -- Most of the time is spent entering address and credit card numbers. if you use PayPal and if the site supports it, you can avoid those. You can buy as a guest and avoid the password. If they offer USPS small package shipping, it runs about half the price of UPS.

1/2 hour -- Find your Location and Register.
This is a good time to do this -- You have committed by buying the hardware and can't work on it yet. By registering now that gives me a week to set up your SFTP (Secure File Transfer Protocol) to the web page.

Login is required to enter your unique latitude / longitude, direction and nearest weather station for your monitor.

1 hour -- Load the Raspberry Pi Operating System on the SD card -- Using a PC (Windows 10) -- I can't help on Apple Macintosh.

1 and 1/2 hours -- Install the Operating System on Raspberry Pi

Note: If you will be using your existing monitor, keyboard and mouse on the Raspberry Pi, You will be working without these instructions for the next 3 hours. If finding your Wi-Fi Security Key routerpass is dependent on your monitor, keyboard, and mouse, this would be the time to find it. See "Find the Router (Windows)" under the Password table notes (above). You need to login admin to your router password typically entering or in your browser URL to bring up your router login screen. After logging into your router, find your Routername and the routerpass (Wi-Fi Security Key). You will need these below to connect to the internet from the Raspberry Pi.

If you have a smart phone and you want to read this Define page on it, Open so you can read these instructions. Else, Under Contents in the Left Pane, Right Click Define and choose Open link in New Tab. Select that tab and File > Print.
Use this same link from the Raspberry Pi when you are ready to download software. -- 2 minutes

1 and 1/2 hours -- wire up -- do this outside of the box -- work on the existing open system.

3 hours -- Load monitor software, and test.

If you are working with one set of monitor, keyboard, and mouse, it is time to bring them back to your PC.

Before you leave the Raspberry Pi:

Leave the Raspberry Pi and running. It's OK to remove the Mouse, Keyboard, and Monitor while it is running. I do it in that order so I can still see the app running before I remove the Monitor.

1 hour -- Install FileZilla, VNC -- On your PC

The holes are in the removeable bottom lid and front. The box is upside down. Top is inside the open box. I recommend Operating System Installation, monitor software installation, and testing before you mount anything in the box.

6 hours -- Cut the Openings in the box

Put six holes in the box. This time seems high but that is what it took me.
It would be nice to have some mechanization or a laser cutter, or different tools, or more skill.

1 and 1/2 hours -- Mount the sensors in the box
