Senseair - Model K33 LP T/RH -Low-Power Module
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).
- 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 power consumption 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.
