K33 LP T

K33 LP is a low-power module that fits in any application where it is important to keep power consumption at a minimum without sacrificing performance. The platform is designed for integration into a host apparatus, such as battery operated products. The module also measures temperature, and humidity is an option.

Defining attributes

  • 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.
