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 serial communication (RS-232) and can be used for Arduino and Raspberry Pi projects.
Sensor ships with unsoldered connectors (serial comm and CO2 calibration switch).
Please go to step 6 in the following guide for a RS-232 connection example in a Raspberry Pi controlled system.
Here is a Python sample code for reading measurements from K30.
Here is an Arduino example.
Here is the K30 data sheet.
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 periodically you should manually perform 400ppm calibration.
