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

K33 LP is a low-power module. 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 the 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. Optional features are RH/Temp.
