20210506· I have the following sketch for getting data from a co2 sensor. I attached the schematic. The issue I’m having: The sketch seems to reset randomly. I can tell because it runs through void setup multiple times. include <> SoftwareSerial mySerial(12, 13); // RX, TX pins on Ardunio int co2 =0; double multiplier = 1;// 1 for 2% =20000 PPM, 10 for 20% = 200,000 PPM uint8_t buffer ...

20191030· MQ135 is a gas sensor which is sensitive to CO2. The change in CO2 levels changes the resistance of sensor which results in the change in the output of the sensor. The output generated from the sensor is feed to Analog Input to Arduino board ( In my case Arduino Uno). The analog data is taken by ADC of Arduino, according to the voltage levels, it displays CO2 levels in ppm.

The CO2 Sensor Arduino Compatible is the first CO2 sensor in OSHW market. 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 (voltage is lower than threshold), a digital signal (ON/OFF) will be released. It has MG811 sensor module onboard which ...

20210506· Hi. I got the sensor MG811 that senses carbon dioxide, you can see an image of the sensor here I googled to use that sensor properly but i have doubts about the wiring with arduino and the proper way to calibrating. So, i got think i can got the data from AOUT pin, but i really don''t know if i can use the 5V pin from arduino to connect in vdd or i need another source (around 12V).
