20201207· eCO2 is calculated based on H2 concentration, it is not a ''true'' CO2 sensor for laboratory use. Another nice element to this sensor is the ability to set humidity compensation for better accuracy. An external humidity sensor is required and then the RH% is written over I2C to the sensor, so it can better calculate the TVOC/eCO2 values.
20141214· A second Arduino connected to a data logging shield, a DS18B20 temperature sensor and another CO2 sensor was placed on the middle of the DIY incubator after it had been running for at least a day. The door was closed and the incubator was allowed to stabilize for three hours. At this point the Arduino was switched on and began logging temperature and CO2 every 5 seconds. After 10 …

20200730· My sensor is the MHZ16 and is capable of 50,000 ppm. i will need to measure more than 5k ppm. i really need some help here. From my reading of the data sheet, the 1004ms pwm output is scaled to the range of your sensor. If you have purchased the 050000ppm (05%) sensor, then that is what the output should reflect.

By knowing the exact concentration of CO2 (Carbon Dioxide), we can do something to reduce the CO2 and to protect our Earth. Here is the Arduinobased CO2 sensor designed by DFRobot lovely engineer. This is the first CO2 sensor in the Arduino market. The output voltage of the module falls as the concentration of the CO2 increases.

20200413· The sensor specs say it can draw up to 150ma, which is WAY MORE than the Arduino 5 volt can supply. Try connecting the sensor directly to a 5 volt supply.
20180618· The MHZ16 NDIR CO2 Sensor costs and comes with a UART to I2C adapter. This makes powering it and communicating with it quite simple: just connect four wires to the development board of your choice! I used an Arduino Nano to read the values from the sensor and send them to the laptop over the USB connection that was also powering it.
