Raspberry pi co2 sensor


Add the following snippet to your HTML:. Project tutorial by alfred This project is about monitoring CO2 levels at home, in the greenhouse, in that small office, etc. This is a NDIR, digital, auto-calibrating sensor, so it's pretty easy to use. I am now starting a new open source project, this time using Arduino. This photo shows K30 connected to Arduino. CO2 measurements are displayed on LCD screen.

And here is a close-up of the sensor. It can also be connected over serial and it has a ppm calibration switch. Please log in or sign up to comment.

While the SCD30 sensor module is not the cheapest, it is quite accurate and easy to use. In addition to the CO2 level, the SCD30 can measure temperature, humidity and works within a wide voltage range between 3. In this article we will focus on the very basics of the SCD If you choose another Raspberry Pi, make sure to buy the correct power supply for it.

Simplepush is an app for iOS and Android which lets you send push notifications to your phone from your Raspberry Pi. Simplepush also lets you send encrypted push notifications. Download the app from Google Play or the App Store.

When you open the app for the first time, you will immediately get a six-digit key that identifies your phone with the Simplepush API. We will later need this key to send out an alert when the CO2 level rises above a certain threshold.

I2C is a commonly used standard which gives modules, like the SCD30, the ability to talk to other devices that support the I2C standard. Since you already enabled I2C and wired everything together, you can ignore the first two steps and continue with installing required packages.

CO2 sensors have to be calibrated in order to give accurate measurements. In ASC mode the lowest measurements within a seven day period get assigned to ppm. The sensor also has to run without being turned off for the whole period to finish the self-calibration successfully. Now all that is left is creating the script that sends out a push notification once the CO2 level is above a certain threshold. Replace YourSimplepushKey with the key that you got when installing the Simplepush app on your phone.

After saving the cronjob file, the script runs every five minutes and sends out a notification when the CO2 level is above the defined threshold. Simplepush Blog.

Now, in order to prototype faster, I got a T-type breakout, a solderless board, and rainbow cable, plus jump wires. Now, it was a while since my college days that I had work on a solderless board but fortunately there is a diagram to connect the sensor to an arduino board thus you can deduce how to wire it to the equivalent pins on a Raspberry Pi.

With this diagram, and the official Raspberry Pi documentation, I was able to find the correct pins without much issue. Finally, with the help of the T-type breakout, and the solderless board, here is a picture of the connections. Note that the breakout already labels the pins so is not hard to match them. Here is the command:. This was the tricky part of the project as the documentation in the wiki of the seller had mostly C code which somehow was factually incorrect once I compared it to the official programming and interface guide.

I struggled about a day using the wiki, so I finally started to search for the sensor documentation instead of Arduino IDE examples.

To build the web service itself I used Express to handle the HTTP requests coming from Prometheus and a small library called node-exporter-prometheus to generate the Gauge metric type to expose the sensor data. The initSensor function will apply the initialization logic required for the sensor to start reading the environmental data. It follows the following diagram:. These are the two methods required to initialize the sensor. As you can see, this is very straightforward.

You choose either if you want to read or write from a sensor and how many bytes. You pass a Buffer or get one depending on the operation. After that is just a matter of inspecting the bytes returned according to the datasheet. Here is the relevant snippet of code:.

Now, with everything wired together, here is the resulting payload when sending an HTTP request omitting comments and other metrics.

Great job! Double check what you've done. After that readings should be considered good after 20 minutes of running. CCS have some interesting features read datasheet - one of them being the temperature drift compensation. In a nut shell, the CCS firmware use external temperature and humidity as data source for reading compensation algorithm.

In accordance with this, --all option add these values in the return json value as follows:.

Despite, I think the TT value might NOT be related to the ambient temperature, but also this might be a internal thermal sensor value which is pair with a infrared heater they are necessary for measuring CO2 concentration by NDIR Non-dispersive Infrared method. So, returned temperature value might be not match with real temperature.
