Overview
Great and powerful sensor for everyone that wants to know the exact concentration of CO2(Carbon Dioxide) in the air.
This is the first CO2 sensor compatible with Arduino. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the CO2 concentration is high enough (the voltage is lower than the threshold), a digital signal (ON/OFF) will be released.
- It has MG-811 sensor module which is highly sensitive to CO2 and less sensitive to alcohol and CO, low humidity & temperature dependency.
- Onboard heating circuit brings the best temperature for sensor to function. Internal power boosting to 6V for heating sensor best performance.
- This sensor has an onboard conditioning circuit for amplifying output signal.
To ease the difficulty of using this CO2 sensor, a Gravity Interface is adapted to allow plug&play. The Arduino IO expansion shield is the best match for this CO2 senor connecting to your Arduino microcontroller.
This is an electrochemical Arduino-based CO2 sensor, it is suitable for qualitative analysis.
- Air Quality Control
- Ferment Process Control
- Room Temperature CO2 concentration Detection

I'm excited to share the details of my BT Arduino Tank project, which incorporates some impressive 3D-printed components. While the main chassis of the tank was not 3D-printed, I utilized this technology to create two crucial parts: the enclosure for the motor driver and the compartment housing the remaining electronics. Additionally, I 3D-printed a cannon for an added touch of customization. The enclosure for the motor driver served as a protective housing, ensuring that the L298N motor driver module was securely mounted and shielded from external elements. By designing and 3D-printing this part, I could precisely fit it to the tank's specifications, providing a neat and organized arrangement of the electronics. In the same vein, the compartment for the remaining electronics, such as the Arduino Nano Every and the HC-05 Bluetooth module, was also 3D-printed. This enclosure offered a clean and organized solution for housing these components, safeguarding them while maintaining easy access for maintenance or modifications. Lastly, to enhance the tank's appearance and add a touch of personalization, I designed and 3D-printed a cannon. This custom-printed cannon perfectly complemented the overall design, making the tank even more visually appealing. By strategically incorporating 3D printing into specific parts of the project, I achieved a balance between functionality and customization. The precision and versatility of 3D printing allowed me to create tailored enclosures and a unique cannon, elevating the overall aesthetic and practicality of my BT Arduino Tank project.
When you want to paint the walls in your bedroom that very specific shade of Misty Irish Green, all you have to do is head to your local hardware store and have them scan the corresponding card. The paint-mixing machine will then add the pigment to a white base and, a few minutes later, you have that exact color. So, shouldn’t you be able to do the same thing with acrylic paint for hobby purposes? Now you can, thanks to the “Color By Code” machine designed by Caltech students Frida Moreno and Asmat Kaur Taunque. Moreno and Taunque built Color By Code for a class project and it is, essentially, a hobby version of those hardware store paint-mixers intended for acrylic paint. As is the standard across many industries that deal with pigments, paint, and printing, this works using CMYK (cyan, magenta, yellow, key) color mixing. Here, the key is black and the machine takes an input color value for each component, then dispenses the paint in those ratios to achieve the desired hue. That all happens under the control of an Arduino Nano Every board. That operates peristaltic pumps, via L298N motor drivers, that dispense each color. Afterwards, a flushing procedure clears the lines before the next mix. The pumps fit into a 3D-printed stand, with the hoses dropping below to a waiting container. At this time, the user must set the color values through serial commands. But the team hopes to create a Bluetooth app in the future. They also plan to add a weight sensor, which would improve the machine’s accuracy.
