atmospheric carbon dioxide sensing with an Arduino ...

18/06/2018· The sensor can be calibrated in atmospheric CO2 conditions at the push of a button. I have reservations about this one-point calibration but “you pays yer money…”, as my dad used to say. The Nano is sitting on a screw terminal shield with mount holes for easy connections ($4 well spent for making secure, non-permanent connections to the Arduino). On the laptop screen you can see data ...

CO2 sensor and real-time plotter - Arduino Project Hub

This is a simple and fairly inexpensively air quality sensor. It measures CO2 and total VOC (volatile organic content) levels in the LCD display and two status LEDs indicate the CO2 level. If desired, the unit can be connected to a computer to display the evolution of CO2 and TVOC in real-time. Technical principle. The air quality is ...

How to Use an Oscilloscope -

An oscilloscope is only good if you can actually connect it to a signal, and for that you need probes. Probes are single-input devices that route a signal from your circuit to the scope. They have a sharp tip which probes into a point on your circuit. The tip can also be equipped with hooks, tweezers or clips to make latching onto a circuit easier. Every probe also includes a ground clip ...

DSO 138 - an entry-level oscilloscope • Wolles Elektronikkiste

25/11/2020· For this experiment, I controlled an I2C component with the Arduino and “intercepted” the SCK line signals with the oscilloscope. I chose the 100 kHz I2C mode because 400 kHz (fast mode) is resolved too poorly by the DSO 138. But even with 100 kHz we reach the limit. The signal cannot be resolved more finely. With a time base of 20 s, it disappears from the display.
