The K-30 Sensor Module is a maintenance-free transmitter module intended to be built into different host devices that require CO2 monitoring data.
The compact size, low-power requirements and multiple output options are intended to facilitate integration into analog or microprocessor-based controls and equipment.
This sensor supports I2C and serial communication (RS-232) and it can be used in Arduino and Raspberry Pi projects.
Sensor ships with unsoldered connectors for I2C (or serial comm) and CO2 calibration switch.
The sensor comes pre-configured for 400ppm auto-calibration (ABC calibration). If you use the sensor in a closed environment (e.g. greenhouse), we can turn off ABC calibration on your sensor, which means that you will manually perform 400ppm calibration whenever needed.
FOR RASPBERRY PI PROJECTS:
FOR ARDUINO PROJECTS:
The sensor draws more than 300mA in operation. For Arduino projects you will need an external 5V power supply for your sensor. DO NOT CONNECT ARDUINO VCC TO YOUR EXTERNAL POWER SUPPLY VCC.
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.
