K30 CO2 Sensor Arduino

Application Note AN 126: Arduino UART Interface to K 30 Sensor

CO2 sensors using an industry‐standard UART TXD‐RXD connection. Two examples are described: 1. Basic ... Connecting the K30 Sensor Refer to the wiring diagram below for the Arduino Uno or Arduino Mega 2560. The connections for Arduino MEGA are identical to the Mega2560. Important: A 6‐9 VDC, 500 ma or greater, external power supply is highly recommended since the K‐30 draws 300+ma when ...

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

· 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 ...

TGS4161 CO2 Research Arduino Project Hub

K30 CO2 Sensor to verify the readings; " TFT display to make some readings without going online ; So far I''ve identified few things that i would like to share with other having the same goal. Accuracy: If used correctly the sensor is VERY accuarte. I am comparing it to my K30 CO2 (which is rated ~3% accuracy) and I can tell that response times and readings are within 5% difference ...

CO2 Monitoring with K30 Sensor

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.
