3.000.496 – SENSIRION

The SENSIRION 3.000.496 is a self-contained module integrating a non-dispersive infrared (NDIR) CO2 sensor with a capacitive relative humidity and temperature sensor. The module provides calibrated and temperature-compensated digital outputs via an I2C interface, operating at a supply voltage of 3.3V to 5.5V. The CO2 sensor utilizes a single-beam dual-wavelength principle for enhanced long-term stability and accuracy, with a typical measurement range of 400 ppm to 5000 ppm and an accuracy of ±(30 ppm + 3% of reading). The RH/T sensor offers a relative humidity measurement range of 0% to 100% RH with a typical accuracy of ±3% RH, and a temperature measurement range of -40°C to 85°C with a typical accuracy of ±0.3°C. The module incorporates internal filtering and signal processing to minimize the impact of environmental noise and drift, ensuring reliable performance in demanding applications.
