Oct 01, 2019· When adding higher power sensors to the circuit, the input power supply may need to be changed. For example, when interfacing with the K30 CO2 sensor, which requires 5 to 9 V and as much as 300 milliamps of current during startup , a 4xAA battery pack could be used. A 1 N4001 diode should then be used on the input power to add reverse voltage ...

CO2 Monitoring with K30 Sensor -

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 on Github: K30_CO2_I2C_Arduino. This photo shows K30 connected to Arduino. CO2 measurements are displayed on LCD1602 screen.

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

Aug 10, 2021· 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.

Senseair K30 CO2 sensor from First Cypress on Tindie

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 Data Sheet. Here is K30 I2C Communication Guide. Here is the most recent I2C Bus specification.
