Winsen MH-Z19C NDIR CO₂ Sensor for HVAC and Indoor Air Quality
Lead Time
Product Description
Winsen MH-Z19C NDIR CO₂ Sensor for HVAC and Indoor Air Quality is designed for the sensing and monitoring work identified in its specifications. It gives a compatible controller or monitoring system access to the quantities this model is designed to measure. The Working Voltage specification is 5.0 ± 0.1 V DC. The Detection Range specification is 400–10,000 ppm (optional range). The Resolution specification is 1 ppm. When choosing this sensor module, start with the documented configuration. The measurement range and signal output should suit the job before you choose a sensor. Supply, mounting and environmental limits are separate checks; any stated calibration or handling requirements also remain relevant. The dimensions figure is 32.9 × 19.7 × 8.6 mm. The Detection Gas specification is Carbon Dioxide (CO₂). The Detection Principle specification is Non-Dispersive Infrared (NDIR). The Accuracy specification is ±(50 ppm + 5% of reading). The Average Current specification is <40 mA at 5 V.
