arduino - How do I edit the EEPROM of a K30 CO2 sensor ...

2021-08-10· 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 ...

CO2 Monitoring with K30 Sensor - Arduino Project Hub

2017-06-20· 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, auto-calibrating 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 …

Read Two K-Series CO2 Sensors with Arduino Uno | …

With these tools, the K30 sensor will operate in multi-drop 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 …

Precalibrated CO2 sensor - Sensors - Arduino Forum

2021-05-06· 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 .

CO2 Monitor - Arduino Project Hub

And where Rs410 is the sensor resistance measured in clean air (410 ppm of CO2) and f_RH_T_410 is the correction factor at the moment that the clean air sensor resistance is measured. Here we assume that the correction factor as a function of relative humidity and temperature is equal for CO2 and hydrogen. I do not have any calibration gasses ...

k-30 co2 sensor - flashing lights? - Sensors - Arduino Forum

2021-05-06· Hi, I've got a K30 hooked up and measuring quite nicely, but I'd like to have it as part of a sensor suite inside a room. Problem is, the flashing lights from the K30 are pretty noticeable during the nighttime! I wondered how anyone else has tackled the problem.. Difficult to box it up as the air won't be circulating. I did look through the sensor PDF and couldn't see anything obvious.

Senseair K30 CO2 sensor from First Cypress on Tindie

I needed a easy to use Co2 meter that wasn't expensive for testing air quality in some buildings. The K30 sensor have been a good choice. It have been very easy to interface with an Arduino, although I used the serial connection instead of the reccomended SPI interface. The sensor gives a correct reading only 4 seconds after the Powerup.
