K33 ELG

K33 ELG is suitable for low power applications since the unit can be put into sleep-mode between measurements. The sensor measures and stores records of environmental parameters such as CO₂, RH, and temperature.

Defining attributes

Low-power consumption
CO₂, RH, and temperature
Maintenance free
Long term stability

The K33 ELG is a sensor module for measuring CO₂ concentration, temperature, and relative humidity.

ELG is designed for low-power application with demand for multiple measurement parameters. The adjustable measurement interval results in average current that can be reduced to less than 52 μA (one measurement every 60 minutes).

As all other sensors from Senseair, the module is designed for high volume production with full traceability by sensor serial number on all manufacturing processes and key components. Every sensor is individually calibrated and is provided with UART digital interface

This platform is designed to be a low power OEM module for integration into host apparatus, such as battery operated products and sensors with radio transmitters – any application where it is important to keep power consumption at a minimum without sacrificing the performance.ustable measurement interval results in average current that can be reduced to less than 52 μA (measurement 1/60 min). The module is designed for low-power application. As all other sensors from Senseair, the module is designed for high-volume production, with full traceability by sensor serial number on all manufacturing processes and key components. Every sensor is individually calibrated and is provided with a UART digital interface.
