Senseair - Model K33 BLG -Low-Power Module

• CO₂, Temp & RH
• Configurable sampling and measurement periods
• Logger functionality
• Configurable logging resolution

K33 BLG is a sensor module for measuring percentage range of carbon dioxide concentration, ambient temperature, and relative humidity. It is very easy and small to integrate and operate. It works either by battery-operation or continuous-power. The measurement interval and the logging frequency can both be configured to fit a required time resolution. All this results in adaptable and very low average power consumption to fit many requirements, both regarding long battery-operated lifetime and low disturbing thermal output and self-heating.

The sensor module is designed for flexible integration into multiple host apparatuses (e.g. with battery, radio-transmitters, pumps etc.), or for the most simplistic stand-alone logging device. The durable and precise high-range optical bench, the hydrophobic- and oleophobic diffusion filter paired with Senseair’s renowned maintenance-free technology make the sensor ideal for reliable measurement in many harsh installation environments.

BLG as such can be used for low-power and battery applications. The sensor module has a large integrated memory for storing of the environmental parameters and timestamping. For continuous non-battery installation or when extracting data from memory, the sensor is equipped both with I²C factory edge-connector and with a UART digital interface and communicate through Modbus.
