Building a CO2 Sensor at home!
Building a CO2 Sensor at home!
Using Arduino, you can build your own sensor!
You will need:
CO2 sensor (https://smile.amazon.com/DFROBOT-Gravity-Analog-Sensor-Arduino/dp/B00R5CCH7U/)
Arduino Uno (https://smile.amazon.com/Arduino-A000066-ARDUINO-UNO-R3/dp/B008GRTSV6/)
Expansion Board (https://smile.amazon.com/gp/product/B00G3IKO68/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1)
Arduino software (https://www.arduino.cc/en/Main/Software&)
Instructions:
Instructions:
Take the Arduino Uno board and attach it onto the circuit holder with four screws.
Take the expansion board and attach it onto the Arduino Uno board.
Connect the CO2 sensor and the expansion board using the three wire cable provided with the sensor.
4. Connect your computer to the Arduino board using the USB cable.
5. Open up the Arduino software, and use the code found at this website.
6. Upload your code and save it with an appropriate name. The upload button is the second button in the picture shown.
7. Click on the Serial Monitor button, which is the last button in the menu on the top right corner to see the data coming form the sensor.
8. Let your sensor run for 48 hours to calibrate. The numbers may look high at the start, but the calibration will fix that.
Final Product:
Final Product:
After calibration, your serial monitor should be showing CO2. In this case, the CO2 in the area of the sensor was less than 400ppm.
