  • Ultra-Low Power Consumption
  • Low Profile

The CozIR LP is our NEW ultra-low power, low profile CO2 sensor - it's the lowest power CO2 sensor on the market today. The CozIR LP can run on a compact battery, removing the need for larger batteries and super-capacitors. That represents half the power consumption of the best-in-class competing CO2 sensors. At less than 8mm tall it's 85% smaller than the CozIR ambient sensor, which equates to a 40% space saving.
