K33 LP T/RH

K33 LP T/RH is a low-power module that measures CO₂, temperature and humidity. The adjustable measurement interval results in average current that can be reduced to less than 52 μA (one measurement every 60 minutes).

Defining attributes

  • Maintenance free
  • Low Power
  • Individually calibrated
  • Long term stability

K33 LP T/RH is a low-power module that measures CO₂, temperature, and humidity. The adjustable 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.
