K30-CO2 Sensor

The K30 CO₂ Sensor Module is a high-performance, non-dispersive infrared (NDIR) sensor designed to provide accurate, reliable, and real-time carbon dioxide (CO₂) monitoring. Developed by SenseAir, it is ideal for integration into ventilation systems, indoor air quality monitors, HVAC controls, and building automation systems.

This compact module features a built-in optical cavity, microcontroller, and advanced signal processing, offering direct digital and analog outputs. Its long calibration interval, low power consumption, and maintenance-free design make it ideal for indoor air monitoring, CO₂ alarms, and environmental sensing.
