20211121· The SCD30 is an NDIR sensor, which is a ''true'' CO2 sensor, that will tell you the CO2 PPM (partspermillion) composition of ambient air. Unlike the SGP30, this sensor isn''t approximating it from VOC gas concentration it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...
20170620· I tried a number of analog CO2 sensors for that project, but I ran into calibration issues until I got a K30 CO2 module. This is a NDIR, digital, autocalibrating sensor, so it''s pretty easy to use. I am now starting a new open source project, this time using Arduino. I uploaded a I2C library for this sensor on Github: K30_CO2_I2C_Arduino. This photo shows K30 connected to Arduino. CO2 ...
20210423· These two jumper cables are important as they will allow both the EZOCO2 sensor and the Arduino Uno board to communicate with each other. Next, place the red jumper cable into the 5V pin. And finally, place the black jumper cable into any of the 2 GND or ground pins near the 5V pin. These two jumper cables will now supply power and a ground line from the Arduino Uno to the EZOCO2 …

With these tools, the K30 sensor will operate in multidrop environment like RS485 MODBUS and I2C as the sensor has a programmable address. So when using the Arduino you may address multiple sensors as unique devices, like I2C devices. With the addition of a 485 transceiver at the Arduino and each sensor the UART RX/TX from the Arduino can communicate with multiple sensor slaves. The sensors ...
K30 Co2 Sensor giving 2 different readings from UART and I2C I am using a K30 Co2 sensor and having difficulties with the readings when it is connected via I2C it reads the average co2 about 400 which is normal, when i switch over to Uart and using analog pins 15 16 as digital pins it gives me a reading that is always twice that of I2c.
I2C connection: SCL and SDA on K30 are 3V3 pins. Most Arduinos (except Due) have 5V I2C bus, so a voltage level converter is needed (refer to figure 2 in Phillips Application Note 97055). Here is an Arduino test sketch that uses K30 over I2C. Here is K30 …
20161018· And, for the record, the Mini is taking code from the arduino IDE superbly. I was able to get an HTU21D sensor working pretty easily on pins D1/D2 so I decided to give it a try with the CO2 sensor. This is the ''provided'' code from the company, and I''ve changed the pins to reflect D1/D2 (though I would prefer to use other pins if possible)
20210506· Would you mind telling me how you connect your K30 with Arduino successfully? I have tried using individual power source 5V battery pack but still the same 203 reading from sensor. I have tried using individual power source 5V battery pack but still the same 203 reading from sensor.
20210506· A Carbon Dioxide Sensor would make sense in a Greenhouse where a level of 1% or 1000ppm would make sense. Atmospheric CO2 is typically 360 to 385 ppm. (< .04%) It only becomes an issue when it reaches several percent of the local atmosphere. Suggesting that CO2 is an indicator of “air quality” (unless in a sealed space) is a bit of a stretch .
Customers using the Senseair K30 1% and 3% CO2 sensors with the Arduino MCU and the supported library occasionally see “lockup” of the sensor. It appears that the sensor sends negative data and quits working. After unplugging the sensor from power momentarily, it works seems to be a random problem. Fortunately, we have been able to recreate the problem, and have several ...
The CO2 concentration is calculated from the measured resistance and the temperature/relative humidity correction. It may be written as: CO2 = 410*ppm*(Rs/f_RH_T / Rs410/f_RH_T_410)^b. Where the exponent b is equal to according to Mad Frog. And where Rs410 is the sensor resistance measured in clean air (410 ppm of CO2) and f_RH_T_410 is ...
20210810· While working on a circuit to log carbon dioxide with a K30 CO2 sensor using an Adafruit Data Logging Shield, I ran into a problem. The I2C address of the RTC on the shield has a collision with the address of the CO2 sensor. The address of the RTC is baked into the silicon and cannot be changed, but the address of the K30 sensor is mutable. According to the I2C guide (see PDF in I2C/I2C_comm ...
While the Arduino''s 5V power is theoretically able to power the K30, the sensor needs 300mA minimum to operate the light inside the sensor. The problem is, if you power the Arduino from your PC''s USB port, the K30 has to share power with the Arduino, your mouse, and any other devices on the USB bus. The power to the sensor will drop under ...

20150501· The YoctoCO2, with its embedded SenseAir K30 sensor. ABC automatic calibration. Automatic calibration is based on the fact that in a common environment, the CO2 level comes back to the norm (400ppm CO2) periodically, at least every few days. Starting from there, the sensor constantly monitors the lowest observed CO2 level over a period of several days. If these lowest values diverge …
