CO2 Engine® K33 LP T/RH

CO2 Engine K33 LP T/RH is a low-power module that measures CO2, temperature and humidity. The adjustable measurement interval, results in average power consumption that can be reduced to less than 52 μA (measurement 1/60 min). The module is designed for low-power application. The module is as all other sensors from SenseAir 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.

 

 

 

 

Key benefits

-Low-power consumption-Individually calibrated-Maintenance-free-Long term stability

 

Applications

This platform is designed to be a low-power OEM module for integration into host apparatus, Such as battery operated products, sensors with radio transmitters. Any application where power consumption is important to keep at a minimum without sacrificing the performance.
